陕西省动物源性食品中二口恶英类化合物污染调查分析
|
摘要
目的调查陕西省10个地市典型的动物源性食品中二口恶英类化合物的污染情况。方法于2017年4月采集具有代表性的食品(猪肉、牛肉、鱼肉、鸡蛋),采用高分辨气相色谱-高分辨双聚焦磁式质谱联用仪定量检测29种二口恶英类化合物的含量。结果 4种食品中鱼肉的毒性当量(toxic equivalent quantity,TEQ)最大,为0. 085 pg TEQ/g,猪肉、牛肉和鸡蛋中TEQ值分别为0. 049、0. 034和0. 040 pg TEQ/g。从地域分布来看,二口恶英含量较大的样品包括安康的鱼肉样品和汉中的猪肉样品,但均低于欧盟所规定该食品种类限值。结合膳食消费量,计算获得4种食品的每月总膳食摄入量为2. 01 pg TEQ/kg,远低于联合国粮农组织/世界卫生组织食品添加剂联合委员会规定的每月耐受量70 pg TEQ/kg。结论陕西省10个地市居民由二口恶英类化合物摄入而导致的健康风险处于较低水平。
Objective To investigate the pollution level of dioxin-like compounds in animal-derived foods from 10 cities of Shaanxi Province. Methods Collect four representative food samples( pork,beef,fish and eggs) to determine the concentrations of29 types of dioxin-like compounds by high-resolution gas chromatographs/high-resolution mass spectrometers( HRGC-HRMS). Results The result showed that the toxic equivalent quantity( TEQ) value of dioxin-like compounds in fish was 0. 085 pg TEQ/g,which was the biggest among the 4 food samples. The TEQ values for pork,beef and eggs were 0. 049,0. 034 and 0. 040 pg TEQ/g,respectively. The TEQ values of dioxin-like compounds were higher in the fish meat of Ankang and the pork of Hanzhoung,but were lower than the max limit of commission regulation European Union. The total dietary intake of the above four foods was 2. 01 pg/( kg·BW·month),which was much lower than the provisional tolerable monthly intake( PTMI) of Joint FAO/WHO Expert Committee on Food Additives 70 pg/( kg·BW·month). Conclusion The residents in the 10 cities of Shaanxi Province are at a low health risk caused by the intake of dioxin-like compounds.
