工业化生产的金针菇Cr和Al污染监测与健康风险评估

Objective] To provide scientific basis for the edible safety of flammulina velutipes in industrial production，[Methods] the contamination status of Cr and Al in the flammulina velutipes and cultivation substrate used for post-sterilization produced by Chongqing Hualu Biological Co., Ltd. from June 2022 to May 2023，with food safety national standards- first method of determination of multiple elements in food under inductively coupled plasma mass spectrometry（ICP--MS method），The coefficient of variation, single factor pollution index and multi--factor composite pollution index were analyzed, and the health risk assessment, enrichment coefficient, main hazards and risk alert were carried out. [Results] The detection rates of Cr and Al were 5.56% and 8.33% respectively in 36 batches of Flammulus revolutus. Al had the highest pollution rate. The variation coefficients of Cr and Al were 6.47 and 8.38% respectively, and the dispersion of Cr was higher than that of Al. The single factor pollution index and the multi-factor pollution composite index are both < 0.7, which is the safe level and is not polluted. The adult pollution index THQ and TTHQ in Cr and the adult pollution index THQ in Al were all < 1, which had no significant effect on adult human health, and the pollution index THQ and TTHQ in Al children were > 1. Health risks to children were present. The enrichment capacity of Cr is higher than that of Al, and the pollution value of Cr meets the limit requirements of China vegetable and the pollution value of Al meets the limit requirements of EU food standards. The main harm of Cr and Al pollution value to human health is briefly reviewed. [Conclusions] Cr and Al in flammulina velutipes production by industrial in Chongqing is not polluted. Cr limit value meets the requirements of Chinese vegetable and Al limit value meets the requirements of European Union food. Flammulina velutipes has a high safety level, and has no obvious impact on adult human health.
