摘要： In this study, 321 chestnut samples from Shandong Province in China were analysed for the presence of mycotoxins. We screened for 14 mycotoxins including aflatoxins (AFs: AFB(1), AFB(2), AFG(1), AFG(2)), deoxynivalenol (DON), 3-acetyldeoxynivalenol (3-ADON), 15-acetyldeoxynivalenol (15-ADON), T-2 toxin (T-2), zearalenone (ZEA), ochratoxin A (OTA), fumonisins (FB1, FB2, FB3), and penicillic acid (PeA). Mycotoxins were detected in 56.4% of the samples, and 11 of these mycotoxins were found. Thirty samples from the Shandong Province markets were deemed positive for AFs (9.3%) and had an AFB(1) level of >2 mu g/kg or a sum of AFB(1), AFB(2), AFG(1), and AFG(2) that was >4 mu g/kg, which exceed the maximum tolerable level of the European regulations standards (EC/188/2006). The contamination level for total mycotoxins found in chestnuts was in the range of 0.6-2,791.0 mu g/kg. The estimated daily intake (EDI) values for each individual mycotoxin and for all of the mycotoxins collectively were calculated by both a deterministic approach and a probabilistic approach. For risk characterisation, dietary exposure to DON, ZEA, FBs, and OTA through consumption of chestnuts, analysed according to both approaches, showed no health risk to Chinese adolescents and adults from exposure to either individual mycotoxins or in combination, but more concern should be paid to the AFs for adolescents and adults at a high consumption level. This is believed to be the first work performing risk assessment of multiple mycotoxins specifically for adolescents, including the recently isolated FBs and PeA, which have recently emerged as mycotoxins of concern, in chestnuts of Shandong Province in China.
