摘　　要：Bisphenol compounds(BPs)are of concern worldwide as potential environmental contaminants,and these chemicals may migrate into animal-derived foodstuffs from animal feeds.In this study,12 BPs were analyzed in 7 varieties of animal feed groups totaling 203 samples collected from various provinces in China.6 BPs were found in these feed samples,with a total detection frequency of 75.5%.The total concentration of all BPs(S6BPs)in each type of feed ranged from below the limit of detection to 75.3 ng g^(-1),with an overall mean value of 4.52 ng g^(-1).The frequency of BPs contamination and the S6BPs values were found to be higher in animal-based feeds(P_(frequency)>0.05,P_(concentration)<0.01)than in plantbased feeds.BPA and BPS were the predominant BPs in these feed samples,accounting for(on average)63.9%and 24.6%of the total BPs,respectively.Overall,the mean concentrations of BPA in these animal feeds were much lower than the legal limits set by China and European Union,implying a low direct risk to both animal health and animal-derived food safety.However,the evident risk of the contamination of various animal-derived food items with BPs passed through the feed chain merits further investigation.
