Abstract
In this research, we used a new model to determine the risk of 58 current use insecticides and acaricides, mosly applied for agricultural purpuses. The OECD POV & LRTP Screening model used to calculate the environmental risk of pesticides using indices of overall persistence (POV), long-range transport potential (LRTP), and intake fraction (IF) was calculated using USES-LCA 2.0 & Simple Box 3.0 . Integrating these parameters with acceptable daily intake (ADI), LD50 bee, LD50 mice and LC50 fish made possible the risk assessment of 58 of current used pesticides. Screening and raking results showed that of 13 acaricides, 38% calssified with low, 38% with medium and 24% with high risk level. Of 45 studied insecticides 31.7% showed low risk, 26.9% showed medium, 23.8% with high and 15.8% showed very high risk. Risk assessment based on the most important crop/fruits demonstrated that pome and stone fruits 42.9%, pistachio 41.2%, citruses 35%, soybean 10%, sugarbeet 29.4%, vegetables 17.6%, cotton 26.3% and cereal (wheat and rice) 31% of insecticides and acaricides are classified with low risk. Therefore, according to the results of the current research, it is clear that risk management of insecticides and acaricides in Iran toward reducing risk level is possible.
