Abstract:
Objective To assess the dietary risk of organophosphates pesticides residues in some vegetables in Shaanxi Province. Methods The monitoring data of organophosphorus pesticides in vegetables from 2012 to 2016 were derived from Shaanxi Province Food Contamination Monitoring Network. The exposure of organophosphorus to vegetables by using exposure risk index (ERI) , dietary exposure risk index (RI) and dietary exposure risk assessment. Results Exposed risk index (ERI) of organophosphorus in some vegetables in Shaanxi Province ranged from 1.25E-06 to 1.87E-01, and among them, the highest ERI of clozaptid in garlic was 1.87E-01, followed by onion. In some vegetables, the highest exposure to organophosphorus was isocarbophos of fresh beans with an exposure of 4.27E-02 μg / (kg body weight · day) and the lowest dietary exposure was bulbs, and stems and fresh beans were 2.00E-04μg / (kg body weight·day) . The exposure of organophosphorus to all kinds of vegetables was less than their respective daily allowable intake (ADI) . The risk of dietary exposure to organic- phosphorus in vegetables was 187％ and greater than 100％ for the risk index (RI) of lettuce, and RI for all other vegetables was <100％. Conclusion The dietary exposure and risk index of organophosphates pesticides in some vegetables in Shaanxi Province was safe, and more attention should be paid to dimethoate and isazofos.
