四种市售鸡饲料中铜,锌,铬含量的测定与分析

用原子吸收分光光度法测定了四种市售鸡饲料中铜、锌、铬的含量，通过分析发现各饲料产品中铬的含量均超过标准，其中有一厂家的两种饲料严重超标。另有三种饲料样品中的锌含量超过推荐量，各产品中铜的含量基本正常。笔者认为目前各饲料生产企业较为普遍地存在着滥用重金属类微量元素的现象，希望引起各有关生产企业的重视

Determination and Analysis of Cu Zn Cr Contentin Four Kind of Chicken Feeds Sold on Market

The Cu Zn Cr content in four kinds of chicken feeds sold on the market in Jingzhou were determined with the method of atomic absorption spectrometry.After analyses we discovered that the Cr content in the four productions are higher than the standard level,in them two kind of productions producted by a plant have very high Cr content far more than the standard level.The Zn content in three kinds of feeds is higher than recommendation.The Cu content is normal essentially in every production.The result told me that it is very common fact that heavy metal microelements had been abused in many feed plants,they are hoped to pay attention to it.
