Shandong is a significant region for grape production in China, but the presence of pesticide residues in table grapes represents a major concern for consumer health. This study aimed to investigate pesticide residues and exposure in table grapes from Shandong Province. Of the 86 survey samples, pesticides were detected in 80 (93.0%), all above the limit of quantification (LOQ) of residues. The most commonly detected pesticide was Dimethomorph, which was found in 65 (75.6%) of the samples in a concentration range from 0.007 to 4.27 mg/kg. The results were evaluated according to the maximum residue levels (MRLs) set by Chinese regulation. Among the contaminated samples, 6.98% exceeded the MRLs and more than one pesticide contamination was found in 65 (75.6%) of the samples. The short-term and long-term risks associated with consuming these grapes were both below 10%, indicating no significant threat to human health. Nevertheless, strict regulation of pesticide residues in grapes is necessary. |
