【摘要】：目的了解北京市朝陽區(qū)市售食用菌中鉛、鎘、砷、汞、鉻及鎳6種元素的含量水平,并評(píng)價(jià)其食用安全性。方法從8個(gè)市場采集了9種新鮮食用菌和5種干制食用菌,共計(jì)94份樣品,采用微波消解-電感耦合等離子體質(zhì)譜法對(duì)樣品中的鉛、鎘等6種元素的含量進(jìn)行測定。結(jié)果鮮食用菌中6種元素的平均含量依次為鉛鎘砷鎳鉻汞,干食用菌中為鉻鎳鎘鉛砷汞,鮮食用菌中鉛、鎘、砷、汞含量均低于GB 2762—2012的要求,干食用菌中僅個(gè)別食用菌中鉛、鎘、砷、汞含量超標(biāo),占干食用菌總量的4.4%,鉻、鎳的平均含量在鮮食用菌中處于較低水平,在干食用菌中存在較大差異。不同食用菌中元素含量存在較大差異,其變異系數(shù)最大值為204.3%。結(jié)論北京市朝陽區(qū)市售食用菌中鉛等元素的含量總體處于較低水平,食用相對(duì)安全。
[Abstract]:Objective to investigate the contents of lead, cadmium, arsenic, mercury, chromium and nickel in edible fungi of Chaoyang District, Beijing, and to evaluate their edible safety. Methods 9 fresh edible fungi and 5 dry edible fungi were collected from 8 markets and 94 samples were collected. The contents of lead, cadmium and other elements in the samples were determined by microwave digestion and inductively coupled plasma mass spectrometry (ICP-MS). Results the average contents of six elements in fresh edible fungi were lead, cadmium, nickel, chromium and mercury, while those in dry edible fungi were chromium, nickel, cadmium, lead and mercury, and the contents of lead, cadmium, arsenic and mercury in fresh edible fungi were lower than those in GB2762-2012. The contents of lead, cadmium, arsenic and mercury in only a few edible fungi exceeded the standard, accounting for 4.4% of the total amount of dry edible fungi. The average contents of chromium and nickel in fresh edible fungi were lower than those in fresh edible fungi, and there were great differences in dry edible fungi. The content of elements in different edible fungi was different, and the maximum coefficient of variation was 204.3. Conclusion the contents of lead and other elements in edible fungi in Chaoyang District of Beijing are relatively low and relatively safe to eat.
