Abstract:

Pesticide residues in watermelons of Zhejiang Province were analyzed to clarify the types and levels of pesticide residues and evaluate the risk assessment. The results showed that 29 pesticide residues were detected in 288 watermelon samples, three pesticides with high detection rates were pyraclostrobin, acetamiprid and carbendazim. And glyphosate and thiamethoxam were found to exceed the maximum residue limits of China each in one sample, the other detected pesticides met the requirements of standards. The results of single factor pollution indices and acute and chronic dietary exposure risk values proved that the dietary intake risk of watermelons in Zhejiang Province is acceptable, and there is no health risk. What’s more, we should focus on the strict pesticide residue limit of other countries (regions), based on the needs of international trade, to formulate pesticide residue limit standards that meet the actual production of watermelon and protect the health consumers in China. Comparing the difference of domestic and foreign standards to integrate with the international community and improve the competitiveness of China’s watermelon industry.
