Abstract
In order to understand the quality and safety of tea in Qiandongnan, the pesticide residues in tea were determined, and the risk factors of pesticide residues detected in tea were analyzed according to dietary exposure assessment and FSA (Food Standards Agency) risk ranking system. The results show that the detection rate of pesticide residues in tea was 54.05%, with 22 kinds of pesticides detected. The detection rate of single pesticide ranged from 0.90% to 31.53%. According to the maximum residue limit of pesticides in foods (GB 2763—2016), the qualified rate is 97.30%. According to the EU standard limit, the qualified rate is 87.39%. The chronic intake risk (% ADI) of the detected pesticides and acute intake risk (%ARfD) were 0.0037%-1.1780% and 0.03%-41.42%, which are acceptable. Based on the pesticide risk ranking, the pesticides at low, medium and high risk levels are 45.45%, 31.82% and 22.73%, with the highest risk of Carbofuran. Therefore, the risk of pesticide residues in this study was within an acceptable range, indicating their quality and safety were good.关键词
