Application of the theory of planned behavior to model the intention and behavior of tomato growers in pesticide exposure. Heliyon 2024; 10:e35794. [PMID: 39170219 PMCID: PMC11337015 DOI: 10.1016/j.heliyon.2024.e35794] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Revised: 07/27/2024] [Accepted: 08/02/2024] [Indexed: 08/23/2024] Open
Abstract
Widespread and indiscriminate use of pesticides has become one of the most important environmental and public health problems around the world. This study was conducted with the aim of applying the theory of planned behavior model to investigate the knowledge, attitude, and behavior of tomato growers in the face of pesticides in agricultural lands located in Kurdistan province, western Iran. We included 300 tomato growers in this study and they filled up a standard TPB questionnaire containing questions about basic information, knowledge, attitude and behavior about pesticides and their actions for disposing of the residual spray solution, washing place of pesticide sprayer, and the disposal of water from washing the equipment. Most of the respondents, 86.7 %, had not participated in promotional classes on how to dispose of the residual solution. Approximately 46.15, 38.46, and 15.39 % of pesticides contained moderately toxic, slightly toxic and practically non-toxic compounds, respectively. More than two-thirds (89 %) of the tomato growers stated that they leave the water from washing the equipment in the field. In addition, among the three variables of TPB, attitudes had the highest score (3.38), which indicated the positive to relatively neutral attitude of farmers towards the safe use of pesticides. These findings can be useful for planners and environmental organizations to make effective interventions to reduce environmental pollution caused by pesticides. Since the incorrect use of pesticides is one of the important environmental and health factors, education and awareness programs can help farmers to consider the correct use of pesticides and environmental protection more.

Nkwatoh TN, Fai PBA, Tchamba MN, Titaku NE. Dietary risk assessment of drinking water and fish from cultivated wetlands of Ndop. JOURNAL OF WATER AND HEALTH 2024; 22:1075-1087.

Abstract
This study evaluated pesticide exposure practices, and the potential health risks of drinking water and consuming fish from the cultivated wetlands of Ndop, Cameroon. Six hundred and twenty-six questionnaires were conveniently administered to farmers (≥ 26 years old) in a cross-sectional study to assess exposure practices and dietary risks. The Chi-square and Pearson correlation coefficients were used to establish relationships between variables. The PRIMET model was used to predict a worst-case dietary risk. The pesticide handling practices of 90% of farmers were inadequate. Chlorpyriphos, lambda-cyhalothrin, fipronil, and paraquat dichloride posed a possible dietary risk at recommended and applied doses, with chlorpyrifos having the highest exposure toxicity ratio (ETRdiet = 36.72). Paraquat dichloride, fipronil, and lambda-cyhalothrin posed a possible dietary risk at 26.3%, 58.3%, and 62.2% of their recommended concentrations, respectively. Remarkably, the dietary risk for cypermethrin was acceptable at 5.8 times its recommended dose (ETRdietR = 0.29). The significant positive correlation (p = 0.000) between PECfish and ETRdiet, suggests a possible health risk of consuming fish and drinking water harvested from the wetlands, thus the need for replacing pesticides posing possible risks at lower or recommended concentrations with less toxic alternatives and to train farmers on pesticide application practices.

Kumar R, Saini GK, Jawed M. Resilience of aerobic sludge biomass under chlorpyrifos stress and its recovery potential. CHEMOSPHERE 2024; 352:141324. [PMID: 38296207 DOI: 10.1016/j.chemosphere.2024.141324] [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: 07/17/2023] [Revised: 12/15/2023] [Accepted: 01/27/2024] [Indexed: 02/06/2024]
Abstract
Non-agricultural sources of pesticides in urban areas are responsible for their presence in domestic wastewater. Therefore, pesticides are typically found in sewage treatment plants in developed and developing countries as micro-pollutant. The presence of pesticides in the wastewater can impart stress on the aerobic sludge biomass and disrupt the functioning of the plant. However, there exists a knowledge gap regarding the resilience of aerobic sludge biomass towards stress due to the presence of pesticides in the wastewater. This study investigated the impact of chlorpyrifos (CPS) - a widely used pesticide, on sludge biomass and explored its recovery capability when CPS is discontinued in the influent. Four duplicate reactors were operated with different CPS concentrations ranging from 50 to 200 mg/L. Chemical oxygen demand (COD) removal for reactors has ranged within 18-73 % at the steady state of the stressed phase, whereas COD removal for the control reactor was 91 %. CPS stress slightly inhibited filamentous biomass growth. Biomass activity and cell viability have decreased significantly, whereas biochemical contents have varied slightly under CPS stress. The activities of the enzymes dehydrogenase and urease were significantly inhibited when compared to catalase and protease. Amplified ribosomal DNA restriction analysis reflected changes in the microbial community. The discontinuation of CPS has allowed aerobic sludge biomass to recover in its organic degradation capability (COD removal of more than 88 % at steady-state conditions of recovery phase operation), biomass growth, and cell viability. In addition, enzyme activities have retrieved to their original levels, and 78-93 % similarity of microbial community structure has been displayed between CPS-exposed and control reactor biomasses. Overall, the present study has indicated the orderly changes in the quality of aerobic sludge biomass under CPS stress through physico-chemical and biological characteristics. The study also has highlighted the self-recovery of sludge biomass characteristics stressed with different concentrations of CPS.

Abstract
Farmers' agricultural green production technology (AGPT) adoption behavior has attracted extensive attention, while few studies explored the interactive effect of perceived value and government regulations in this process. Therefore, we analyze the interaction effect between perceived value and different government regulations on farmers' AGPT adoption by the Poisson regression model, using micro-survey data from 1491 households in China's Yellow River basin. Furthermore, we examine the heterogeneous effect of perceived value and government regulations on farmers' AGPT adoption behavior considering the change in production scale and farmers' age. The results suggest that perceived value can substitute for incentive government regulation and guiding government regulation, respectively. While binding government regulation can inhibit the promotion effect of perceived value on farmers' AGPT adoption. In addition, the larger the production scale, the more influential the effects of perceived value and government regulations on farmers' AGPT adoption are. In contrast, with the increase in farmer's age, the promotion effect of perceived value becomes weak while the effect of government regulations experiences a U-shaped trend. Finally, the conclusions and policy implications are set forth.

Abstract
This study aims to determine the optimal strategy and driving factors of the critical nodes of pesticide packaging waste recycling by constructing the recycling process of "village collection-town transport-county management." Counties, towns, and villages are the central nodes of collection, coordination, and communication in the recycling process. Their strategy selection and influencing factor analysis are related to the development of recycling. The county processing center, township transit center, and village recycling center were selected to construct a game model, and strategy and parameter assumptions were made to obtain the optimal strategy combination. The results showed that strict supervision, professional transportation and strict implementation are the best strategies for counties, towns and villages, respectively. Simulation analysis confirmed that factors such as cost, reward restricted the strategy selection of each subject. The higher the supervision, transport, and input costs, the lower the enthusiasm of counties, towns, and villages to participate in recycling, respectively. Reasonable control of reward could help each participant choose a stable strategy. The study provided the idea of a pilot before promotion for the government and emphasized the importance of controlling incentive policies and relative costs to improve the recycling process of pesticide packaging waste.

Abstract
The excessive use of pesticides is posing major threats to humans and the environment. However, the environmental exposure and impact of pesticides in Pakistan have yet been systematically reviewed, despite the country's leading role in pesticide use. Therefore, this study identified and then reviewed 85 peer-reviewed scientific publications on the topic. It was found that, compared to the worldwide average, Pakistan had high consumptions of pesticides, with an alarming increase of 1169% in the last two decades. The quantities of pesticides used followed an order of pyrethroids > organophosphates > organochlorines > carbamates, but organochlorines were the most problematic due to their environmental occurrence, the ability to transport across the media, and identified human and ecological toxicities. Additionally, the misuse or overuse of pesticides by farmers is prevailing due to insufficient knowledge about the risks, which leads to high risks in occupational exposure. These issues are further aggravated by the illegal use or continuous impacts of banned organochlorine pesticides. For the future, we suggested the establishment of organized monitoring, assessment, and reporting program based on environmental laws to minimize contamination and exposure to pesticides in Pakistan. Remediation of the contaminated areas to mitigate the adverse environmental-cum-health impacts are recommended in the most affected regions.

Abstract
BACKGROUND Attainment of safety during pesticide spraying relies on the farmer's knowledge of pesticide use, attitude and sense of safety. However, such investigations are insufficient in the current study area. METHODS The study is based on a primary survey of 384 orchardists about the myriad of aspects affecting the use of pesticides and their subsequent effects. RESULTS The study revealed that knowledge, attitude, and perception had a weighted average index (WAI) and a standard deviation (SD) of 2.85 ± 1.17, 3.55 ± 1.34, and 3.81 ± 0.98 correspondingly. The findings reflect the farmers have a low to moderate level of knowledge, a moderate attitude toward pesticides, and a favourable perception on their utilization. Thus, for farmer personal protective equipment (PPE) use, it scored 2.77 ± 0.90 on the WAI scale, indicating that most farmers use PPEs 'rarely to occasionally' and that none use full protective gear. Furthermore, attitude and PPE usage exhibited a negative relationship with age, as younger people use PPE more than older ones. The findings were consistent for both farming experience and PPE usage. Moreover, there exists a positive association between age with perception and farming experience, knowledge with perception and PPE use, and attitude with perception. CONCLUSIONS The coefficient of determination (R2) shows that 67.2% of the variability in farmers' PPE use was attributed to factors including knowledge, attitude, perception, and education. A favorable behavioral shift in pesticide usage may be achieved by enhancing farmers' knowledge, attitudes and perceptions, and adequate PPE usage.

Abstract
Disregarding protective measures when handling pesticides in agricultural production imposes increased health risks and health costs on farmers as well as degrades the natural ecosystem. In Pakistan, where agriculture is the prime occupation in rural communities, there is overwhelming evidence of indiscriminate use of hazardous pesticides by farmers without taking adequate precautions. Using cross-sectional data, we examined personal protection and health costs to vegetable growers due to pesticide exposure and determinants of farmers' pesticide handling practices. The theory of averting behavior was used, and the possible factors affecting farmers' adoption of safety equipment and of disposal methods for pesticide containers were estimated using a logit model. Health effects (P < 0.05) and farmers' protection and health costs (P < 0.01) are found as important determinants of farmers' adoption of safety equipment and of disposal methods for pesticide containers. The mean protection and health cost of pesticide exposure per farmer per vegetable season in 2019 was US $3.60. Analytical outcomes indicate that safe and recommended pesticide handling practices are needed to be introduced through adequate integrated pest management (IPM) training programs and by improving farmers' formal education. Thus, creating awareness through IPM training programs among vegetable growers and enhancing formal education to encourage the adoption of precautionary measures and safe disposal methods for pesticide containers may reduce health risks and health costs. Findings imply that adoption of adequate pesticide handling practices would further help reduce occupational hazards and promote sustainable agriculture in Pakistan.

Abstract
Inappropriate handling of pesticides in agriculture poses a major risk to the environment and human health, but factors affecting farmers' behavior are diverse and often unclear. The present study examined farmers' behavior in safe pesticide use (disposal of spray solution leftovers, places for washing sprayers, disposal of rinsates, and use of personal protective equipment) in Ardabil Province, Iran by applying the well-known theory of planned behavior, which states that attitudes, subjective norms, and perceived behavioral control of individuals shape intention and engagement in a specific behavior. Almost 30% of the farmers threw pesticide spray solution leftovers away, while the remaining farmers kept it for next spraying. Concerning place for washing sprayers, 55.3% of the farmers washed sprayers in their home yard, 21.0% washed them in the river or the canal flow, and 14.7% washed them in the water source of the farm. Just less than two-thirds (64.3%) of the farmers said that they leave the rinsates onto the farm, while almost one-third (34.0%) said that they pour the rinsates into the river or the canal flow. Most farmers used trousers and blouse and to a lesser extent mask, gloves, and hat when handling pesticides. Attitudes towards safe pesticide use showed the highest mean score (2.91), illustrating neutral to relatively negative attitudes of farmers towards safe pesticide use. Intention showed the lowest mean score (2.28), indicating poor motive to use pesticides safely. Attitudes showed positive impact, while perceived behavioral control showed negative impact on intention. Subjective norms had no significant impact on intention. These three constructs totally explained 78.1% of the variance in farmers' intention towards safe pesticide use. Improving attitudes and perceived behavioral control of farmers towards safe pesticide use through extension education should be targeted for improving farmers' intention and behavior towards safe pesticide handling.

Abstract
Environmental pollution as a result of the improper disposal of pesticide packaging wastes (PPWs) has posed serious harm to groundwater, soil and public health. However, few studies focused on PPWs green disposal willingness and behaviors of farmers from the perspective of perceived value. Based on the first-hand data, collected from 635 farmers of grain-producing counties in Henan province of China, through the questionnaire survey method, this paper adopted a structural equation model (SEM) to empirically explore the formation mechanism of perceived value on PPWs green disposal, and green disposal willingness and behaviors were further in-depth investigated. The results showed that the action of farmers' green disposal of PPWs followed the causal relationship, whereby perceived value→behavioral willingness→behavioral performance, and farmers' perceived value came from the comprehensive tradeoff and comparison between perceived benefits and perceived risks. Meanwhile, the perceived benefits and perceived risks could have significant effects on green disposal willingness and behaviors directly and indirectly, among which perceived benefits (0.478) had the greatest positive total effects on the willingness, and perceived risks (-0.362) had the greatest negative total effects on the behaviors. Interestingly, there existed inconsistence between farmers' green disposal willingness and behaviors. When faced with the choice of PPWs green disposal, the farmers were generally risk averse, which resulted in them being more inclined to take conservative behaviors driven by the profit maximization, and even showed the "powerless" state with willingness but no actual action.

Abstract
Background: Farmers and their workers are exposed to a wide variety of pesticides. The use of pesticides has been documented to lead to several adverse health effects. Inhibition of cholinesterase, primarily butyrylcholinesterase is a good indicator of occupational exposure to organophosphates and carbamates.Objective: This case-control study aims to study the risks associated with pesticide exposure among farmers and agricultural workers in the Souss Massa region by analyzing variations in the response of a pesticides exposure biomarker: Serum Cholinesterase Activity (butyrylcholinesterase (BChE)).Materials and methods: This was a prospective study conducted on 133 participants (71 farmers and 62 non-farmers). A structured questionnaire was applied collecting socio-demographic information and determining knowledge and work practices in relation to pesticide use. The activity of Serum cholinesterase was measured by the butyrulthiocholine method a spectrophotometric assay.Results: The mean age of the participants was 42.5 ± 10.66 years. The study demonstrated significantly lower BChE activity, respectively, in the plasma of farmers exposed to pesticides, compared to the control group (p < 0.05). The measured mean level of BChE activity was (7304.80 ± 1939.99 U/L) and (9746.42 ± 1699.85 U/L) in the farmers and the control group (non-farmers), respectively. In addition, a high proportion of farmers reported that empty containers are burned in the open (74.6%) for waste disposal. A proportion (11.3%) of farmers also reported that empty container waste is spilled on the farm.Conclusions: The decrease in BChE indicates a serious public health problem among farmers who use organophosphate pesticides. This study suggests that regular monitoring for blood cholinesterase and effective interventions to reduce pesticide exposure to prevent health effects should be provided to farmers.

Abstract
The data presented here are from the Offinso North District Farm Health Study (ONFAHS), a population-based cross-sectional study among vegetable farmers in Ghana. The paper addresses knowledge, pesticide handling practices, and protective measures related to pesticide use by self-reported symptoms for 310 adult farmers who completed a comprehensive questionnaire on pesticide management practices and health. In addition, an inventory was prepared using information supplied by pesticide sellers/dealers in this district. We report that cough and wheezing (but not breathlessness) are positively associated with stirring pesticide preparations with bare hands/drinking water while mixing/applying pesticides, and stirring pesticide preparations with bare hands/drinking water/smoking cigarettes while mixing/applying pesticides. There is a significant exposure-response association between the number of precautionary measures practiced while handling pesticides and cough and wheezing but not with breathlessness. We also found unsafe practices to be associated with sexual dysfunction, nervousness, and lack of concentration. The results also suggest a negative association between practice of any precautionary measure when mixing/applying pesticides and sexual dysfunction, nervousness, and lack of concentration. We found that in spite of the fact that farmers have adequate knowledge about the environment and health effects of pesticides, several unhygienic practices are in widespread use, indicating that knowledge is not necessarily always translated in action. Further action is necessary to promote the safe use of pesticides and to replace existing poor management practices among these and other farmers in Ghana.

Abstract
OBJECTIVES The main objective of this study was to assess pesticide handling and storage practice, and its associated factors among farmers engaged in irrigation in Gondar town, Ethiopia, 2019. Community-based cross-sectional study was used to assess pesticide handling and storage practice, and its associated factors among farmers. Simple random sampling technique was used to select study subjects. Semi-structured questionnaires were used to collect data. Data were entered using Epi Info 7.0 and exported to SPSS 20. Descriptive statistics were used for some variables. Univariate and multivariable binary logistic regression was used to test the factors associated with the outcome. Adjusted odd ratio (AOR) and 95% confidence interval (CI) with P value less than 0.05 were used to report association. RESULTS About 409 study subjects completed the semi-structured questionnaires. Among the studies subjects, 261 (63.8%) of them had poor pesticide handling and storage practice. Knowledge [AOR = 3.23 (95% CI 1.91, 5.46)], attitude [AOR = 1.77 (95% CI 1.11, 2.81) and educational status (informal education [AOR = 3.05 (95% CI 1.72, 5.42)], elementary education [AOR = 5.38 (95% CI 2.62, 11.06)], secondary education [AOR = 9.51 (95% CI 4.24, 21.32)] and certificate and above [AOR = 6.00 (95% CI 1.58, 22.78)]) were factors significantly associated with pesticide handling and storage practice. To improve the pesticide handling and storage practice, it is imperative to enhance the level of the farmer's knowledge through training, and information dissemination in workshops.
