Monitoring and probabilistic risk assessment of chlorothalonil residues in vegetables from Shandong province (China).

The aims of this study were to investigate the contamination status of chlorothalonil pesticide residues in vegetables from Shandong province, and to assess the potential risk of chlorothalonil to consumers based on vegetable consumption and body weight using an improved non-parameter probabilistic model. The results showed that Young children (8 months-6 years old) were more sensitive than General population(above 1year-old). In general, the health risk of chlorothalonil residues to 2 consumer groups via vegetable exposure was low, and the level of residual chlorothalonil was below the Acute Reference Dose (ARfD). This result would provide useful information for re-evaluating pesticides and for revising the chlorothalonil standard in vegetables.
