- 摘要:
- 为保障农产品安全和居民健康饮食，采用湿法消解处理，并用电感耦合等离子体质谱（ICP-MS）法测定哈尔滨水产养殖基地鱼类中7种微量元素（Cr、Cu、Zn、As、Cd、Hg、Pb）的含量。结果表明：哈市水产养殖基地中养殖的鱼类品种相对单一；各微量元素总平均浓度范围为0.002 37~6.747 μg·g-1，7种所研究微量元素在鱼体中浓度顺序为：Zn>Cr>Cu>As>Pb>Hg>Cd。在不同食性的鱼类中As元素浓度为：肉食性鱼>滤食性鱼>杂食性鱼>草食性鱼。总体来说，样品中必须及非必需微量元素含量均相对较低，大家可以放心食用。
- Abstract:
- Processing the samples with wet digestion,and seven kinds of trace elements(Cr,Cu,Zn,As,Cd,Hg,Pb) in Harbin Aquaculture Base fish food were measured with inductively coupled plasma mass spectrometry (ICP-MS).The experiment proved that Harbin Aquaculture Base fish were relatively single variety.The study of trace element concentrations in fish followed the order of Zn>Cr>Cu>As>Pb>Hg>Cd.In different types of food of fish,Arsenic element concentrations followed the order of carnivorous fish>filter feeding>omnivorous fish>herbivorous fish.Overall which,the contents of essential trace elements and non essential trace elements in the samples were relatively low which rest assured to eat.
