Abstract:

This study investigated pesticide residues and dietary exposure risks in strawberries from Zhejiang Province. A total of 150 samples from 9 regions (Hangzhou, Huzhou, Jiaxing, Jinhua, Shaoxing, Taizhou, Wenzhou, Quzhou, Ningbo) were analyzed for 78 pesticide residues. The results revealed that 82.0% of samples contained detectable pesticide residues, with procymidone (45.3%) and boscalid (40.0%) demonstrated the highest detection rates. Multi-residue occurrence (≥2 pesticides) was observed in 58.67% of samples; in total, 30 pesticides were identified, of which 16 were not registered for use on strawberries. The chronic dietary exposure risk quotient (cRQ) ranged from 0.000 4% to 0.730 0%, and the acute dietary exposure risk quotient (aRQ) ranged from 0.025% to 18.600%; Hazard Index (HI) analysis indicated that long-term cumulative risks (insecticides: 0.03%-0.90%; fungicides: 0.30%-1.80%) and short-term cumulative risks (insecticides: 0.40%-9.60%; fungicides: 1.00%-19.90%) were far below 100%. These findings indicate the presence of multi-pesticide residues in Zhejiang strawberries, but the dietary exposure risks remain within safe limits, and the health risks to consumers are considered acceptable.
