Abstract
OBJECTIVE The aim of this study is to evaluate whether the exposure to a low dose of nickel could determinate a variation in levels of progesterone in outdoor workers. MATERIALS AND METHODS Two hundred sixty one subjects were divided by sex, task, age, seniority, and cigarette smoking habit. For each workers was evaluated the dose of blood progesterone and urinary nickel.The statistical analysis was performed. RESULTS The Pearson correlation showed a statistically significant correlation between urinary nickel levels and progesterone. The multiple linear regression showed a significant correlation between progesterone and urinary nickel in the total sample and in the subgroups of smokers and workers with tasks of traffic direction. CONCLUSIONS The results of our study suggest that occupational exposure to low doses of nickel present in urban pollution may influence to progesterone levels in outdoor workers.

Abstract
Introduction: The aim of the present study was to evaluate whether there are changes in cardiovascular risk factors among noise-exposed workers and to explore the possible mechanisms of a long-term noise exposure leading to cardiovascular disease and the sex differences of cardiovascular risk factors in this population. Materials and Methods: Two hundred workers engaged in noise-related work, and a control group of 200 nonnoise-exposed workers hospitalized for occupational health examination were assigned into the study. All workers underwent a medical examination, electrocardiogram recording, blood pressure test, other blood tests, and audiometry. The collected blood was used to detect homocysteine (HCY), renin, angiotensin II, and other markers of cardiovascular risk factors. Results: Our study suggests that the type of work with long-term exposure to noise might pose a cardiovascular risk, as evidenced by associated increases in plasma HCY levels, incidence of type 2 diabetes, and incidence of hypertension. Discussion: Our research also reveals that among male workers, the levels of triglycerides, uric acid, HCY, renin activity, and the incidence of hypertension are higher than female, while high-density lipoprotein cholesterol is lower than female workers had. Additionally, the study emphasizes again the importance of weight control for reducing cardiovascular risk. Conclusion: Our study suggests that noise is a cardiovascular risk factor. Interventions in the work environment could be a preventable and controllable manner for reducing the incidence of cardiovascular disease.

Abstract
OBJECTIVES The aim of this study is to evaluate whether exposure to low concentrations of cadmium (Cd) can have effects on the thyroid hormone level of outdoor workers exposed to urban pollutants. METHODS The study was conducted on a final sample of 277 individuals (184 males and 93 females). The environmental monitoring of Cd was evaluated through the use of portable dosimeters, while the biological monitoring was achieved through the assessment of urinary Cd and thyroid hormones. The total sample was divided according to sex and task. The Pearson's correlation coefficient among the variables was calculated after subdivision on the basis of sex and task. The multiple linear regression was performed to take into account the major confounding factors. RESULTS Statistical tests showed a negative correlation between urinary Cd levels and free triiodothyronine and free thyroxine and a positive correlation between urinary Cd and thyroid-stimulating hormone levels. CONCLUSIONS Our early results seem to point out that occupational exposure to low concentrations of Cd present in urban air affects the thyroid hormone levels in exposed workers.

Abstract
UNLABELLED The aim of the present study is to evaluate whether workers in the sanitary fixtures industry are a category at risk of developing cardiovascular diseases, and in particular, whether chronic noise exposure may play a role in cardiovascular effects in exposed workers. Seventy-five employees engaged in sanitation fixtures production and a control group of sixty-four office workers, who were not exposed to agents that could damage the cardiovascular system, participated in our study. The selected workers completed a clinical-anamnestic questionnaire, and underwent a medical examination, blood pressure test, electrocardiogram (ECG), blood tests, and audiometry. Measurements of environmental noise, dust, and lead were also carried out. The exposed workers, in comparison to the control group, showed a higher frequency of hypertension, systolic and diastolic blood pressure (p<0.05, p<0.05), as well as electrocardiographic abnormalities (p<0.05). There was also a higher frequency of hypertension and electrocardiographic abnormalities among subjects with audiometric deficit compared to normoacoustic subjects (p<0.05 and p<0.05). RESULTS from our study suggest that work activity in the sanitary fixtures industry can have an influence on the cardiovascular system, and noise can be the main cause of damage for the cardiovascular system in exposed workers, as cardiovascular damage seems to be linked to hearing loss.

Global review of studies on traffic police with special focus on environmental health effects. Int J Occup Med Environ Health 2014; 27:523-35.

Abstract
Since occupation is a major determinant of health, traffic police personnel face multiple occupational hazards. They are continuously exposed to vehicular emissions and work in a noisy and polluted environment. The objective of the present review is to explore the impact of occupational health hazards on the health of traffic police personnel. Published research papers on traffic police reporting occupational health issues were accessed and reviewed. Attempts were made to access papers that reported negative associations in order to present a balanced review. The majority of the studies have reported a decrease in the lung function and increased respiratory morbidity. The research on the cytogenetic abnormalities or genotoxic effect of vehicular emissions arising due to long-term exposure to benzene and other polyaromatic hydrocarbons has provided conflicting results, since more or less equal numbers of studies have given evidence for and against the causal association. There is a vast accumulation of epidemiological evidence on the casual association between vehicular pollution and its carcinogenic effect. Multiple studies have concluded that traffic police are highly stressed. A number of occupational factors have been attributed to stress among traffic police. Occupational health studies help us to understand the effects of vehicular pollution and its adverse influence on workers. They also provide opportunity for defined exposures measurements and precise risk assessment. The findings from these studies are easily generalizable and can help us understand the impact of air pollution on the general population.

Abstract
Nickel (Ni) and Ni compounds are widely present in the urban air. The purpose of this study is to estimate exposure of individuals to Ni and the correlation between this exposure and the values of blood counts in outdoor workers. This study focused on a sample of 101 outdoor workers (55 male and 46 female; 65 nonsmokers and 36 smokers), all employed in the municipal police in a large Italian city. The personal levels of exposure to Ni were assessed through (a) environmental monitoring of Ni present in the urban air obtained from individual samples and (b) biological monitoring of urinary and blood Ni. The blood count parameters were obtained from the hemochromocytometric tests. Pearson correlation coefficients ( r) were calculated to assess the association between the blood and urinary Ni and the complete blood count. Multiple linear regression models were used to examine the associations between the complete blood count and the independent variables (age, gender, years of work for current tasks, cigarette smoking habit (current and never smoker), values of airborne Ni, and blood and urinary Ni). Multiple linear regression analysis performed on the total group of 101 subjects confirms the association among the red blood cells count, the hematocrit, and the urinary Ni ( R2 = 0.520, p = 0.025 and R2 = 0.530, p = 0.030). These results should lead to further studies on the effects of Ni in working populations exposed to urban pollutants. The possibility that the associations found in our study may be partially explained by other urban pollutants (such as benzene, toluene, and other heavy metals) not taken into consideration in this study cannot be ruled out.

Abstract
The aim of this study is to estimate whether the occupational exposure to low dose anesthetic gases could cause alterations of blood parameters in health care workers. 119 exposed subjects and 184 not exposed controls were included in the study. Each worker underwent the complete blood count test (CBC), proteinaemia, leukocyte count, serum lipids, liver and kidney blood markers. The liver blood markers show statistically significant differences in health care workers compared with controls (p<0.05), a statistically significant decrease in neutrophils and an increase of lymphocytes in health care workers compared with controls (p<0.05). The prevalence of values outside the range for GPT, GGT, total bilirubin, lymphocytes and neutrophils was statistically significant in health care workers compared with controls (p<0.05). The results suggest that occupational exposure to low dose anesthetic gases could influence some haematochemical hepatic and hematopoietic parameters in exposed health care workers.

Abstract
The aim of our study is to verify whether the exposure to low Ni doses in urban air may have some effects on the prolactin values of outdoor workers exposed to urban pollutants. 334 workers have been included in the study and divided on the basis of gender, job, age, length of service and smoking habits. Each worker underwent urinary Ni and prolactin sampling. The t-test for independent samples, the Mann-Whitney U test for two mode variables (gender, smoking habit), the univariate ANOVA test and the Kruskal Wallis test for the variables in more than two modes (age, length of service and job duties) were performed on the total sample. Pearson's correlation coefficient (p two-tailed) among the parameters was evaluated both in the total sample and after the stratification by gender, smoking habit and job. Multiple linear regression was performed after taking account of the major confounding factors on the total sample and on the subcategories. The statistical tests showed a significant correlation between urinary Ni and prolactin both in the total sample and in the subcategories. We believe that the occupational exposure to low doses of Ni present in urban pollution may influence the prolactin values in exposed workers.

Abstract
The technological and industrial progress together with the intensification of vehicular traffic and the adoption of new social habits are the cause of an increasing noise pollution with possible negative effects on the auditory system. This study aims to assess the noise exposure levels and the effects on the hearing threshold in outdoor and indoor male workers of a big Italian city. The study was carried out on 357 outdoor male workers, exposed to urban noise and on a control group of 357 unexposed indoor workers. Noise levels were measured in 30 outdoor and indoor areas. The subjects underwent tonal liminal audiometry in order to determine the value of their hearing threshold. During their working activity, outdoor and indoor workers are exposed to different noise levels LEX<80 dB(A). At mid-low frequencies (250-2000 Hz), the results show significant differences in the average values of hearing threshold between the two groups in both ears and for all age classes; there are no significant differences between the two groups at higher frequencies. The outdoor noise levels measured are not usually ototoxic and the hearing loss at mid-low frequencies is not characteristic of the exposure to industrial noise. For these reasons the Authors hypothesize that the results may be due to the combined effect of the exposure to noise and to ototoxic air pollutants. The impairment of speech frequencies is disabling and involves the risk of missed forensic recognition.

Abstract
The aim of the study was to assess the relationship between occupational exposure to airborne lead (Pb) and alterations in peripheral blood counts in workers of the Municipal Police assigned to different types of outdoor tasks. Then, 337 both male and female subjects were enrolled and divided on the basis of sex, cigarette smoking habit and kind of task. Exposure to airborne Pb, dosage of total blood Pb and peripheral blood count were carried out. A significant positive correlation was detected between the values of total blood Pb and values of plasma reticulocytes (%RET) both in the total sample and for all the classes of the subdivision except for police drivers. Some statistically significant correlations were present but discontinuous for other variables of peripheral blood counts. Results suggest that occupational exposure to low doses of airborne Pb is able to influence lines of the hematopoietic system in exposed workers, with special reference to %RET.

Abstract
The aim of the study is to assess whether occupational exposure to urban stressors could cause alterations in urinary metanephrines levels in traffic policemen vs administrative staff of municipal police. A total of 258 subjects were included in the study: 129 traffic policemen exposed to urban stressors (68 males and 61 females) and 129 controls (68 males and 61 females). Urinary metanephrines mean levels were significantly higher in male traffic policemen compared to controls (p < 0.01). No significant differences were in female traffic policemen compared to controls. In the control group, urinary metanephrines mean levels were significantly higher in females compared to males (p < 0.01). There were no significant differences in urinary metanephrines mean levels in female traffic policemen vs male traffic policemen. The increase in urinary metanephrines mean levels observed in male exposed compared to controls could be related to chronic occupational exposure to low doses of chemical, physical and psychosocial urban stressors.

Occupational exposure to noise and the cardiovascular system: a meta-analysis. THE SCIENCE OF THE TOTAL ENVIRONMENT 2010; 408:681-9. [PMID: 19931119 DOI: 10.1016/j.scitotenv.2009.10.071] [Citation(s) in RCA: 66] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/18/2009] [Revised: 10/27/2009] [Accepted: 10/27/2009] [Indexed: 05/06/2023]
Abstract
The aim of our meta-analysis is to evaluate the association between the modifications of the cardiovascular system and chronic exposure to noise in occupationally exposed subjects. We considered the articles published from 1950 to May 2008. Only 15 papers were conforming to the inclusion criteria identified for this meta-analysis. A total of 18,658 workers were divided in three groups according to the level of noise exposure as measured in the original studies (High Exposure, HE, Intermediate Exposure, IE, Low Exposure, LE). A preliminary evaluation of the type of data allowed for a classification of the type of performed measurements. Two classes of variables were identified: Class I, composed by continuous variables (systolic blood pressure, SBP, diastolic blood pressure, DBP, and heart rate, HR) and Class II, composed by not continuous variables (prevalence of hypertension and prevalence of ECG abnormalities). For each variable the calculation of heterogeneity was performed. For continuous variables the calculation of ES and its significance were performed while Odds Ratio (OR) and its significance were calculated for not continuous variables. The results show a statistically significant increase of SBP and DBP in HE workers compared to LE and IE workers while HR is statistically higher in HE participants compared to LE participants. The prevalence of both hypertension and ECG abnormalities is statistically higher in HE workers compared to LE and IE workers. Taking into account both the extremely high heterogeneity among studies and the ES/OR values we suggest a particular attention to the measurement and evaluation of SBP, DBP and HR in workers with chronic exposure to noise. Also ECG for workers with chronic exposure to noise is suggested in order to identify and evaluate possible abnormalities noise could be a concurrent cause of.

Abstract
The aim of this study is to evaluate whether occupational exposure to urban stressors could cause alterations in the follicle-stimulating hormone (FSH) levels in traffic policemen compared to a control group. After excluding the subjects with main confounding factors, traffic policemen and male controls were matched by age, working life, body mass index (BMI), drinking habit, cigarette smoking history, and daily consumption of Italian coffee, 166 traffic policemen and 166 controls were included into the study. FSH levels were significantly higher in traffic policemen compared to male controls ( P < 0.05). The distribution of FSH values in traffic policemen and controls was significant ( P < 0.05). Our results suggest that occupational exposure to low doses of chemical and psychosocial stressors may alter plasma levels of FSH in traffic policemen more than in the control group. If the results obtained are confirmed by further research, the plasma levels of FSH may be used as early biological markers, valuable for the group, used in occupational set even before the appearance of disorders of male fertility.

Abstract
The aim of this study is to evaluate whether occupational exposure to urban stressors could cause alterations in androstenedione plasma levels in male traffic policemen compared to a control group. After excluding the principal confounding factors, traffic policemen were matched with controls by age, working life, body mass index (BMI), drinking habit, and habitual soy intake in diet. One hundred and ten traffic policemen and 110 controls were included in the study. In male traffic policemen, mean androstenedione values were significantly lower compared to controls. The distribution of androstenedione values in traffic policemen and in controls was significant. Our results suggest that the occupational exposure to chemical urban stressors, interacting with and adding to the psychosocial ones, could alter androstenedione plasma concentrations in traffic policemen compared to a control group. According to our previous research, androstenedione could be used as an early biological marker, valuable for the group to be employed in occupational settings, even before the onset of the endocrine reproductive health diseases.

Abstract
The aim of this study is to evaluate if the occupational exposure to urban stressor could cause alterations in dopamine (DA) plasma levels and related diseases in traffic police officers compared to a control group. After excluding subjects with principal confounding factors, 306 traffic police officers (139 female and 167 male) and 301 controls (134 female and 167 male) were included in the study. In traffic police officers, mean DA values were significantly higher compared with controls (P = 0.006 and P = 0.000 in male and female, respectively). The distribution of DA values in traffic police officers and controls was significant (P = 0.000 and P = 0.000 in male and female, respectively). The number of male traffic police officers with a positive response to the questionnaire's items concerning anxiety, depression and panic attacks was higher than controls, though not significant (7.2% traffic police officers versus 4.2% controls). This difference was also not significant in female traffic police officers compared with controls. According to our previous researches on other neuro-immune-endocrine parameters, DA could be used as an early biological marker, valuable for the group to be employed in occupational sets, even before the onset of pathology.

Abstract
BACKGROUND The aim of the study is to evaluate if occupational exposure to chemical, physical and psycho-social urban stressor could cause alterations in plasma free testosterone (T) levels and related diseases in female traffic police vs. control group. PATIENTS AND METHODS The research was carried out on initial sample of 468 female Municipal Police employees (209 traffic police and 259 controls). After excluding the principal confounding factors, traffic police were matched with controls by age, working life, menstrual cycle day, BMI, drinking habit, cigarette smoking habit, liquorice and soy intake in diet, habitual consumption of Italian coffee. There were 96 female traffic police and 96 controls included in the study. RESULTS T mean levels were significantly higher in female traffic police compared to controls (p=0.000). The distribution of T values in traffic police and in controls was significant (p=0.000). No significant differences were found comparing the percentage in traffic police and controls concerning dystocial, premature and post-term birth. An increase in mental health disorders was found in traffic police compared to controls but the difference was not significant. CONCLUSION The increase in T plasma levels observed in traffic police vs. controls can be due to a chronic working exposure to low doses of environmental chemical urban stressor. According to our previous researches T could be used as an early biological marker even before the onset of the related disorders.

Abstract
The aim of the study is to evaluate if the occupational exposure to urban pollutants could cause alterations on 17-alfa-hydroxy-progesterone plasma levels and related diseases in male traffic policemen. 17-alpha-OH-P is synthesized in Leydig cells and in adrenals; it influences spermiogenesis, acrosoma reaction, testosterone biosynthesis, blocking of gonadotropin secretion; it regulates learning, memory and sleep. After excluding principal confounding factors, i.e., rotating or night shifts, exposure to solvents, paints and pesticides during time-off and smoking, traffic policemen were matched with controls by age, working life and drinking habit. Finally, 112 traffic policemen and 112 controls were included in the study. In traffic policemen 17-alpha-OH-P mean values were significantly higher vs. controls. The distribution of 17-alpha-OH-P values in both groups was significant. An increased frequency of fertility disorders referred to the questionnaire items were found in traffic policemen vs. controls, but the difference was not significant. The occupational exposure to low doses of chemical urban stressor, interacting with and adding to the psychosocial ones, could alter plasma 17-alpha-OH-P concentrations in traffic policemen vs. controls. 17-alpha-OH-P could be used as an early biological marker, even before the onset of the reproductive and mental health diseases.

Abstract
Urban outside workers, such as traffic police, are daily exposed to air pollutants and psychosocial stressors: for these workers, the working environment corresponds to the living environment of the general population. Studies in the literature have shown that immune parameters could be affected by chronic exposure to various chemical pollutants. The aim of this study is to evaluate whether occupational exposure to urban pollutants can cause alterations in NK, IL-2, IFN-gamma and C3 plasma levels in female traffic police compared to a control group. After excluding subjects with the principal confounding factors, 86 female traffic police and 87 controls were matched by age, years of police work and habitual alcohol consumption. The distribution of NK values in female traffic police and controls was significantly different (p=0.000); NK values above the upper limit of the normal laboratory range were observed in 23 female traffic police and in 2 controls (p=0.000). IL-2 mean levels were higher in traffic police compared to controls, but the difference was not significant. The mean and the distribution of IFN-gamma values in female traffic police and controls were not different. C3 mean levels were higher in female traffic police versus controls, but the difference was not significant. Considering that the subjects with the principal confounding factors were excluded from the study and that female traffic police and controls were matched by the above-mentioned variables, our results suggest that chronic occupational exposure to low doses of chemical stressors, which may interact with and add to psychosocial ones, can affect both innate and adaptative immunity.

Abstract
The aim of this study was to evaluate whether traffic police officers exposed to chemical, physical and psycho-social stressors, are at risk for alterations in plasma levels of prolactin (PRL) compared to a control group. Plasma PRL levels were evaluated in 92 male and 51 female, non-smoker, traffic police officers exposed to urban stressors and in 92 male and 51 female controls, matched by sex, age and working life (mean, SD and distribution), after excluding workers with the principal extra-occupational confounding factors. Mean PRL levels were significantly higher than controls in non-smoker, male and female traffic police officers (respectively, p=0.000 and p=0.013). The number of non-smoker, male and female traffic police officers with PRL values outside the upper normal limit for our laboratory was higher than, but not significantly different from controls. Mean PRL levels were not significantly higher than controls in smoker, male and female traffic police officers. The number of smoker, male and female traffic police officers with PRL values outside the normal limit for our laboratory was not significantly different from controls. The results suggest that exposure to urban chemical and physical stressors, interacting with psychosocial factors, may have an influence on PRL levels in traffic police officers. The level of plasma PRL might be a useful early biological marker for workers exposed to urban stressors.

Abstract
OBJECTIVE The aim of the study is to evaluate whether the occupational exposure to urban pollutants including endocrine disruptors (EDs) could cause alterations in plasma 17-beta-estradiol (E2) levels and related diseases (adverse pregnancy outcome and mental health disorders) in female traffic police compared to a control group. METHODS After excluding the subjects with the principal confounding factors, traffic police and controls were matched by age, years of police work, age of menarche, menstrual cycle day, body mass index (BMI), drinking habit, cigarette smoking habit, habitual intake of soy or liquorice in diet and habitual consumption of Italian coffee. Thirty-seven traffic police and 31 controls (seventh day; follicular phase of the ovarian cycle); 38 traffic police and 42 controls (14th day; ovulatory phase of the ovarian cycle); and 25 traffic police and 28 controls (21st day; lutheal phase of the ovarian cycle) were included in the study and then matched for the above-mentioned variables. RESULTS In follicular and in lutheal phases, mean E2 levels were significantly lower in traffic police compared to controls. The distribution of E2 values in traffic police and controls was significant in follicular, ovulatory and lutheal phases. In ovulatory phase, mean E2 levels were lower but not significant in traffic police compared to controls. An increase was found concerning mental health disorders referred to in the questionnaire items in traffic police compared to controls, although the difference was not significant. CONCLUSIONS Considering that the potential confounding effect of extraneous factors was controlled for by restricting the study population and by matching traffic police and controls on the above-mentioned variables, our results suggest that occupational exposure to urban pollutants, EDs included, might alter E2 plasma concentrations. E2 could be used in occupational set as an early biomarker of exposure to urban pollutants, valuable for the group, even before the onset of the related pathologies (adverse pregnancy outcome and mental health disorders).

Abstract
There are few studies in literature about exposure to urban pollutants and effects on female reproductive health. The aim of the study was to evaluate if the occupational exposure to chemical urban stressor could cause luteinizing hormone (LH) plasma levels alterations in female traffic police compared to a control group. One hundred and eighty subjects were included in the study, subdivided into three different groups according to the day of the menstrual cycle (7th, 14th, 21st) in which a blood sample was taken. In follicular and lutheal phase of ovarian cycle, the LH mean levels were significantly higher in traffic police vs. controls. The distribution of LH values in traffic police and controls was significant in follicular, and lutheal phase. In ovulatory phase, LH mean levels were lower but not significant in traffic police compared to controls. An increase was found concerning mental health disorders referred to the questionnaire items in traffic police vs. controls, although the difference was not significant. Our results suggest that occupational exposure to urban stressor in female traffic police, may alter LH plasma concentrations. LH may be used in occupational set as an early biomarker of exposure to urban stressor.

Abstract
The aim of this study is to evaluate whether traffic police exposed to urban pollutants could be at risk of changes on proliferative response of blood lympho-monocytes to the mitogen phytohemagglutinin (PHA) compared to a control group. Traffic police were matched with controls by sex, age, length of service, drinking habits and smoking habits after excluding main confounding factors. So, 77 traffic police exposed to urban pollutants (43 men and 34 women) and 77 controls with indoor activity (43 men and 34 women) were included in the study. The proliferative response of blood lympho-monocytes to the mitogen PHA was significantly lower in male and female traffic police compared to controls (respectively, P=0.000 and 0.014). The possibility of an effect on immune system and therefore on the blood lympho-monocytes proliferative answer in traffic police exposed to urban pollutants, can be assumed.
