Residues of 14 pesticides were determined in 150 cowpea samples collected in five southern Chinese provinces in 2013 and 2014.70% samples were detected one or more residues. 61.3% samples were illegal mainly because of detection of unauthorized pesticides. 14.0% samples contained more than three pesticides. Deterministic and probabilistic methods were used to assess the chronic and acute risk of pesticides in cowpea to eight subgroups of people. Deterministic assessment showed that the estimated short-term intakes (ESTIs) of carbofuran were 1199.4%-2621.9% of the acute reference doses (ARfD) while the rates were 985.9%-4114.7% using probabilistic assessment. Probabilistic assessment showed 4.2%-7.8% subjects may suffer from unacceptable acute risk from carbofuran contaminated cowpeas from the five provinces (especially children). But undue concern is not necessary, because all the estimations are based on conservative assumption.
2013年和2014年在中国南方五个省份采集了150份豇豆样本，测定了其中14种农药的残留量。70%的样本检测出一种或多种残留。61.3%的样本违规，主要原因是检测出未经授权的农药。14.0%的样本含有三种以上农药。采用确定性和概率性方法评估了豇豆中农药对八类人群的慢性和急性风险。确定性评估表明，克百威的估计短期摄入量（ESTIs）为急性参考剂量（ARfD）的1199.4%-2621.9%，而使用概率性评估时该比例为985.9%-4114.7%。概率性评估表明，4.2%-7.8%的受试者可能因来自这五个省份的克百威污染豇豆而面临不可接受的急性风险（尤其是儿童）。但无需过度担忧，因为所有估计均基于保守假设。
