Balogun AO, Weigel MM, Estévez E, Armijos RX. Chronic Occupational Exposure to Traffic Pollution Is Associated with Increased Carotid Intima-Media Thickness in Healthy Urban Traffic Control Police. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:6701. [PMID: 37681841 PMCID: PMC10487607 DOI: 10.3390/ijerph20176701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 08/28/2023] [Accepted: 08/29/2023] [Indexed: 09/09/2023]
Abstract
Urban traffic officers in many low- and middle-income countries are exposed to high levels of traffic-related air pollutants (TRAP) while working vehicle control on heavily congested streets. The impact of chronic TRAP exposure on the cardiovascular health, including the carotid intima-media thickness (CIMT), of this outdoor occupational group remains unclear. This cross-sectional study compared the average mean and maximum CIMT measurements of two groups of relatively young, healthy traffic police (32 ± 7 years; 77% male) in Quito, Ecuador, who were without clinical evidence of serious cardiovascular or other disease. Previously published background data on PM10 (a TRAP surrogate) indicated that street levels of the pollutant were several orders of magnitude higher at the street intersections worked by traffic police compared to those working only in an office. Accordingly, officers permanently assigned to daily traffic control duties requiring them to stand 0-3 m from heavily trafficked street intersections were assigned to the high exposure group (n = 61). The control group (n = 54) consisted of officers from the same organization who were permanently assigned to office duties inside an administration building. Mean and maximum CIMT were measured with ultrasound. General linear models were used to compare the CIMT measurements of the high exposure and control groups, adjusting for covariates. The adjusted average mean and maximum CIMT measures of the high exposure group were increased by 11.5% and 10.3%, respectively, compared to the control group (p = 0.0001). These findings suggest that chronic occupational exposure to TRAP is associated with increased CIMT in traffic police. This is important since even small increases in arterial thickening over time may promote earlier progression to clinical disease and increased premature mortality risk.

Global review of studies on traffic police with special focus on environmental health effects. Int J Occup Med Environ Health 2014; 27:523-35. [PMID: 25034905 DOI: 10.2478/s13382-014-0285-5] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2013] [Accepted: 04/14/2014] [Indexed: 11/20/2022] Open
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
Questionnaires were administered in 272 textile, chemical, food, metal products and woodworking firms in ten cities in industry-dense areas to assess the general OHS situation in Turkey. This paper explores the portion related to exposures of workers to physical and ergonomic hazards. OHS experts where available, firm owners, partners, or engineers responsible for safety were asked to answer structured questions regarding percentages of workers exposed to specific hazards. About 65% of respondents reported exposures to noise risks among at least some percentage of employees; 26.3% reported more than 50% of employees were so exposed. In more than 60% of the firms employees were exposed to ergonomic risks related to the need to meet production quotas and the need to maintain constant posture. The most prevalent risk factors in five industries and the relative frequencies of exposed employees are described.

Abstract
The aim of this cross-sectional study was to compare the blood lead levels of apprentices working in lead-related industries with those of non-apprentice controls and to evaluate the influence of such occupational exposure. The study was conducted between October 2004 and June 2005 in Bursa, Turkey. Subjects included 231 apprentices and 252 male controls, age ranging from 14-19 yr old. Inductively coupled plasma mass spectrometry (ICP-MS) was used to analyze blood lead levels. The overall mean blood lead level was 3.62 microg/dl (95% CI 3.39-3.85), the apprentice mean was 4.99 microg/dl (95% CI 4.60-5.38), and the control group mean was 2.37 microg/dl (95% CI 2.22-2.51). The blood lead level of apprentices was significantly higher than that of controls (p<0.05). Results show that occupational exposure increases the blood lead levels of apprentices, although the impact on their immediate health is low. Measurement of blood lead levels of apprentices should be taken periodically, and a regular medical surveillance program should be established.

Abstract
Lead contamination is a public health problem of world-wide scope that negatively affects the health of especially women and children. Nevertheless, studies on lead contamination and its impact on health in Peru are limited. The objective of the present study was to determine blood lead levels (BLL) of traffic police officers in Lima and Callao compared with values in police officers working indoors and with data obtained in 1992. The study was performed in May-June 2004 and included 52 traffic officers and 50 officers working in police stations in the north, center and east of Lima and Callao, Peru. Both groups were of similar age. The dependent variables were arterial blood pressure and BLL obtained in each officer. In addition a questionnaire was applied to evaluate risk factors for lead exposure. In 2004, the average BLL in traffic police officers was higher (44.7+/-6.1microg/l) than that of indoor police officers (39.3+/-8.2microg/l) (p=0.0001). However, none of the police officers had BLL of over 100microg/l. No differences were observed in the location of the residences of the participants and the respective traffic density. Those over 30 years of age had a higher risk of having a BLL over 42microg/l than younger officers (odds ratio (OR)=4.45). Traffic police officers had a higher risk of BLL >42microg/l (OR=4.80). Compared with data from 1992 obtained from the literature, an important reduction has been observed in 2004. This may be a consequence of the policy to eliminate leaded gasoline in Peru. However, it is still necessary to monitor this policy to ensure the elimination of lead in gasoline.
