  Background and Objective: Increasing population growth and the need to develop agricultural products have increased the use of pesticides and thus the pollution of water resources as one of the environmental problems. Therefore, this study was conducted to determine the residual concentration of diazinon pesticide in the water of Abbasabad River in Hamedan in 2014.Method: Water samples were collected from four stations along the Abbas Abad River. In the laboratory, after sample preparation, diazinon residues were determined using a spectrophotometric method. All statistical analyses were performed using the SPSS software.Findings: The maximum mean concentration of diazinon residues (µg/L) in samples of spring and summer seasons were 97.0 ± 10.2 and 202 ± 13.7, respectively. Also, the mean contents of pesticide residues in the water samples in both seasons were higher than the maximum contaminant levels (MCLs) established by WHO and EPA.Discussion and Conclusion: Due to exceeding the average residual concentration of pesticides in the evaluated water samples, it is necessary to pay attention to issues such as training gardeners in order to use pesticides correctly and in principle. Also, measures should be considered in order to use the water of this river for drinking or farming cold-water fish.  Manuscript profile
