Multi-residue analysis and dietary exposure risk assessment of commonly used fungicides in celery from Zhejiang Province

Abstract

Abstract:

The issue of pesticide residues in celery has been increasingly drawing attention，especially the detection of fungicides. To understand the safety status of fungicides in celery，210 celery samples were continuously collected from production bases in Zhejiang Province from 2022 to 2023，and the residual detection of 26 typical fungicides was analyzed. A comprehensive assessment of the detected fungicides in celery was carried out through acute and chronic dietary exposure assessment of single pesticides and the multi-residue comprehensive safety index method. The results showed that in 112 celery samples，17 fungicides were detected in 210 celery samples，with a detection rate of 53.33%（112/210）. Among them，procymidone（29.52%），pyraclostrobin（27.62%），difenoconazole（14.76%），chlorothalonil（14.29%），carbendazim（13.33%），iprodione（11.90%）and dimethomorph（11.90%）had relatively high detection rates. Procymidone and carbendazim，which were frequently detected，were unregistered pesticides for celery. It is necessary to strengthen the standardized training of pesticide use in celery and encourage enterprises to initiate pesticide registration work. The legality judgment results of the detected fungicides showed a pass rate of 98.10%. The parameters exceeding the standard were difenoconazole（2 times），carbendazim（1 time）and chlorothalonil（1 time）. The multi-residue phenomenon was common in celery，and samples with two or more fungicides detected accounted for 73.21%（82/112）. Although a single fungicide met the limited requirements and the acute and chronic dietary exposure risk assessment was within an acceptable range，the comprehensive safety index method assessment found that two batches of samples had multi-residue risks. The detection rates of procymidone，pyraclostrobin，dimethomorph were all relatively high. The multi-residue phenomenon of pesticides in celery is relatively common in Zhejiang Province. It is necessary to strengthen pesticide supervision to ensure the safe production of celery.
