Abstract :

Chlorpyrifos and 2,4, D toxins are chlorine toxins. Organo chlorine pesticides are a class of toxins Their most important feature is the accumulation in the environment and have a very strong effect on the central nervous system of insects.This study examines and identifies chloropyrifos and 2,4, D toxins in the Susangerd water treatment plant and the effect of the Susangerd water treatment process on the removal of these toxins.In this way, at the entrance of the treatment plant, the output of the treatment plant and a middle stage, sampling is done and the amount of chlorine toxins in each stage is measured.The sampling period is September, October and November 2018. In order to identify and determine the amount of toxins studied, the GC-MS device of the American manufacturer Agilent 7890 was used. Based on the results of this study, chloropyrifos and 2,4,D toxins were detected in the raw water of the treatment plant and with the measurements made, it became clear that Chlorpyrifos 92.38% and 2,4, D 98.2% were removed by the Susangerd refinery process and the residual value was very small and standard. This indicates the efficiency of the said treatment plant.
