Investigating on the Residue of Organophosphate Pesticides in the Water of the Hablehrood River, Garmsar, Iran

Abstract

Background: Organophosphate pesticides are of concern to the drinking water supply and high risks on human health.
 Methods: An occurrence survey was performed in the spring and summer of 2016 for 6 months to assess the preva­lence of organophosphate pesticides in the Hablehrood River that is located in Semnan Province. Besides, 10 kinds of organophosphate pesticides were sampled in 5 stations. Moreover, were measured by Gas Chromatography (GC) was supported by an electron capture detector (ECD) and Turbochrom software. In all stations, Diazinon was detect­ed in the spring and summer, but Malathion only in the spring.
 Results: The highest concentration of Diazinon was observed at the Mahmoud Abad station in spring (0.94ppb) and the Bonekooh station in the summer (0.93ppb). The highest and lowest concentrations of Malathion were detected in Mahmoud Abad (0.35ppb), and Gache station, respectively.
 Conclusion: The concentration of pesticides in BoneKooh and Mahmood Abad was higher than the standard.

Investigation of Residual Concentration of Organochlorine, Organophosphorus, and Carbamate Pesticides in Urban Drinking Water Networks of Hamadan Province, Iran

“…The finding might be explained by the facts that a long time has passed since the pesticides have been used, and these pesticides have relatively low stability in the environmental conditions. Another study by Safari et al (9) to assess the prevalence of organophosphate pesticides in the Hablehrood River found that the concentration of diazinon and malathion in tow stations (Bone Kooh and Mahmood Abad) were higher than the standard level. Also, Khalijian et al (10) in their study to determine residual concentrations of diazinon pesticide in groundwater sources of Hamadan-Bahar plain sampled in summer revealed that the average residual concentration of this pesticide in the samples exceeded the allowed limit in the WHO guidelines.…”

“…Many studies have been conducted to investigate the residual concentrations of pesticides in surface and groundwater resources of Iran and other parts of the world. Safari et al conducted a study to assess the prevalence of organophosphate pesticides in the Hablehrood River located in Semnan province through using GC supported by an electron capture detector (ECD) and found out that the concentration of diazinon and malathion in two stations (Bone Kooh and Mahmood Abad) were higher than the standard level (9). In a study by Khalijian et al aiming to determine the residual concentration of diazinon pesticide in groundwater sources of Hamadan-Bahar plain, it was determined that the mean concentration of diazinon residues in samples was 0.23±0.06 μg/mL, being upper than 0.10 μg/mL which is the maximum contaminant levels defined by the World Health Organization (WHO) (10).…”

Nanotechnology in Sustainable Agriculture, Soil Chemistry and Remediation of Polluted Soil

“…Several anthropogenic activities such as industrial, agricultural, and wastewater play a crucial role in contaminating the soil with persistent organic pollutants (POPs) (polyaromatic hydrocarbon, polychlorinated biphenyls, and pesticides), heavy metals, and also excess nutrients due to misuse of chemical fertilizers (Dror et al, 2017;Safari et al, 2020). Industrial expansion and expanding cities/urban are adding more of solid wastes, chemicals, and solvents, and many POPs.…”

Ultrasound assisted fabrication of InVO4/In2S3 heterostructure for enhanced sonophotocatalytic degradation of pesticides

“…This pesticide's residues spread to rivers, lakes, and seas by runoff brought on by rain due to the continuous and careless use of this herbicide in agricultural fields close to water sources, damaging these bodies of water. Exposure to DZN can cause cholinergic toxicity and damage to the skin and gastrointestinal tract [19] . Hence, treating pesticides and their residues is highly appreciated.…”
