    摘要:

    测定梅州市售10种鲜食用菌和16种干食用菌中31种元素含量,利用内梅罗综合污染指数评价法评估市售食用菌质量等级,并以预计每日摄入量(EDI)、靶标危害系数法(THQ/TTHQ)和致癌风险系数法(CR/TCR)对市售食用菌中5种重金属进行膳食暴露风险评估。结果表明,食用菌中31种元素含量差异较大,钯未检出。鲜食用菌中只有10.08%的铬超标,干食用菌中镉、铬、砷、汞超标率分别为11.06%、11.98%、14.75%、17.51%;重金属内梅罗综合污染指数表明,干姬松茸和干竹荪达到中度污染等级,鲜鹿茸菇、干牛肝菌和干红菇达到轻度污染等级;干香菇处于警戒等级;其余市售食用菌为安全级别。重金属膳食暴露风险评估表明,市售鲜干食用菌中Pb、Cd、Hg、As、Cr的EDI10-4,存在潜在致癌风险。研究表明,梅州市售10种鲜食用菌总体水平安全,干食用菌存在一定的重金属膳食暴露风险,应加强干食用菌的质量监控。

    Abstract:

    The contents of 31 elements in 10 kinds of fresh edible fungi and 16 kinds of dried edible fungi sold in Meizhou were determined. The Nemerow comprehensive pollution index evaluation method was used to assess the quality grade of the edible fungi sold in the market. The dietary exposure risk of five heavy metals in the commercially available edible fungi was evaluated based on the estimated daily intake (EDI), target hazard quotient/total target hazard quotient (THQ/TTHQ) method, and carcinogenic risk/total carcinogenic risk coefficient method (CR/TCR). The results showed that the contents of 31 elements in edible fungi varied greatly, and palladium was not detected. Only 10.08% of chromium in fresh edible fungi exceeded the standard. The over-standard rates of cadmium, chromium, arsenic and mercury in dried edible fungi were 11.06%, 11.98%, 14.75% and 17.51%, respectively. The Nemerow comprehensive pollution index of heavy metals indicated moderate pollution level of dried Tricholoma matsutake and dried Dictyophora indusiata, light pollution level of fresh Pleurotus ferulae and dried bolete and dried Russula vinosa , the risk alert level of dried shiitake mushrooms, and the safety of the rest of the commercial edible fungi. The assessment of dietary exposure risk of heavy metals showed that EDI values of Pb, Cd, Hg, As and Cr in commercial fresh and dried edible fungi were all smaller than PTDI value, THQ was less than 1.0, and TTHQ was less than 1.0, indicating that the non-carcinogenic health risk of fresh and dried edible fungi sold in the market was low. The TCR values of Pb, Cr, As and Cd in fresh edible fungi were less than 10-4, indicating low carcinogenic risk. The TCR of dried edible fungi was higher than 10-4, indicating potential carcinogenic risk. The research showed that the 10 kinds of fresh edible fungi sold in Meizhou were overall safe. There was a certain risk of dietary exposure to heavy metals in dried edible fungi. Therefore, the quality control of dried edible fungi should be strengthened.
