Volume 17, Issue 4 (3-2025)
Abstract
Background and Objective: Monitoring pesticide concentrations in drinking water resources is crucial for enhancing water quality and public health. Therefore, periodic assessments of pesticide levels in these resources are essential to safeguard consumer health.
Materials and Methods: This study aimed to assess the concentrations of six pesticides—malathion, diazinon, glyphosate, paraquat, deltamethrin, and cypermethrin—in agricultural water resources as well as in urban and rural water distribution networks in Fasa city in 2023. Pesticide levels were monitored in 25 drinking water samples and 6 agricultural water samples.
Results: The results show that pesticide concentrations are higher in agricultural water compared to drinking water and distribution networks. Specifically, the concentrations of malathion and diazinon in agricultural water resources are significantly higher than in drinking water, with levels potentially up to eight times greater. The total risk index for samples from agricultural water sources ranges from 0.89 to 1.36, indicating a comparable risk to that of drinking water.
Conclusion: The health risk assessment of malathion, diazinon, glyphosate, paraquat, deltamethrin, and cypermethrin in drinking water resources suggests no immediate threat to public health. However, due to the elevated pesticide levels in agricultural water resources, ongoing monitoring of water sources near agricultural areas is recommended.

Volume 18, Issue 1 (5-2025)
Abstract
Background and Objective: Littered waste is one of the most common forms of pollution in urban environments, primarily caused by citizens’ behavior in waste disposal. This study aimed to investigate the density and composition of littered waste in Behbahan, Iran, in 2023 and assess the pollution status using a specific environmental index.
Materials and Methods: This descriptive cross-sectional study evaluated the density and composition of littered waste in Behbahan's urban environment using visual surveys. The findings on the density and composition of abandoned waste were interpreted using the Clean Environment Index, an environmental ranking method that assesses the severity of litter pollution.
Results: The study revealed that the density of littered waste in the surveyed areas ranged from 0.011/m² to 0.954/m². The average density of littered waste in commercial, residential, and recreational land uses was 0.809/m², 0.196/m², and 0.011/m², respectively. Cigarette butts were the most common type of litter, constituting 61% of the total waste on average. The Clean Environment Index values for the surveyed locations ranged from 0.39 to 32.56, indicating that 63.6% of the sites were categorized as clean or moderately polluted, while 36.3% were classified as extremely polluted.
Conclusion: Given the significant proportion of cigarette butts in the composition of littered waste in Behbahan and their impact on the pollution index, efficient management strategies for this type of waste are crucial. The finding that over one-third of the surveyed locations fell into the "extremely dirty" category highlights the need to enhance the efficiency of the urban cleaning system.
