    Abstract:

    Objective To explore the current situation of pesticide residues in vegetables sold in Tianjin and the risks for Tianjin residents.Methods In accordance with the requirements of “The national food contaminants and harmful factors risk monitoring manual”, 516 representative vegetable samples were collected and tested. The exposure level and potential risk were evaluated by point evaluation method.Results Pesticide residues were detected in 364 of 516 (70.54%) vegetable samples. There were 244 of 516 (47.29%) vegetable samples with two or more pesticides at the same time. 31 of 516 (6.01%) vegetable pesticide residues exceeded the standard. The rank of violation rate was: Organic phosphorus pesticides>carbamate pesticides>pyrethroids pesticides>organochlorine pesticides>fungicide pesticides, which was significant different (χ2=9.84, P<0.05). The top three pesticides with the violation rate were phorate (2.62%, 10/381), carbonfuran (1.55%, 8/516) and cypermethrin (0.90%, 2/223). The results of acute exposure risk assessment showed that carbonfuran %ARfD was 238.89%, phorate %ARfD was 191.67%, greater than 100%, which was unacceptable. Chronic exposure risk assessment showed that IFS of all pesticide was less than 1 and the risk was acceptable.Conclusion The detection rate of pesticide residues in vegetable in Tianjin was high. Especially, combined use of multiple pesticides was prominent, and the use of banned pesticides still existed. Carbonfuran and phorate were risk factors in acute dietary exposure. The government and relevant departments should strengthen the supervision of pesticide residues in vegetables.
