摘要
用冷原子吸收法测定了陕西省部分市县的１４０条鱼、１０７份猪肉、１８０枚鸡蛋、１００份牛奶样品的汞含量。结果表明，鱼肉中汞含量为０．２２３３±０．２４７５ｍｇｋｇ－１，其中２９．３％的鱼样中汞含量超出国家卫生标准中汞允许量；猪肉、鸡蛋、牛奶中汞含量分别为０．００７３±０．００５４ｍｇｋｇ－１，０．００３８±０．００１７ｍｇｋｇ－１和０．００２４±０．０００７ｍｇｋｇ－１，均在国家卫生标准中汞允许量以内。说明环境中汞污染对人体健康的威胁，主要来自汞污染水中的鱼体内蓄积的高含量汞。
The mercury contents in 140 fish,107 portions of pork,180 eggs and 100 portions of milk were determined with cold vapor atomic absorption spectrometry in some cities and counties of Shaanxi Province.The results showed that the mercury contents in fish were 0.2233±0.2475 mg·kg -1 ,29.3% higher than the permitted level of mercury in fish (Hygienic Standard of P.R.C.GB2762 94);the mercury contents in pork,eggs,and milk were 0.0073±0.0054 mg·kg -1 ,0.0038±0.0017 mg·kg -1 and 0.0024±0.0007 mg·kg -1 ,respectively,all of which were below the permitted level of mercury in foods (GB2762 94).It is suggested that the mercury threat against humans health mainly comes from high mercury content of fish living in contaminated water.
