浙江水产养殖环境中铬的形态分析和污染情况调查

本文对浙江省池塘养殖、滩涂养殖、浅海筏式养殖、工厂化养殖和网箱养殖等典型养殖模式环境中铬的污染情况进行抽样调查，根据本单位开发方法对总铬和有效态铬中的两种价态铬进行测定。结果表明，我省水产养殖环境中，水质中总铬和毒性较大的Cr6+含量较小，均在《生活饮用水卫生标准》（0.05mg/L）限量标准以下，未发现超出渔业水质标准的情况。

Morphological Analysis and Pollution Investigation of Chromium inZhejiang Aquaculture Environment

In this paper, the pollution of chromium in the environment of typical culture modes such as pondculture, beach culture, shallow raft culture, factory culture and cage culture in Zhejiang Province is sampledand investigated, and the two valence chromium in total chromium and effective chromium are determined ac?cording to the development method of this unit. The results show that in the aquaculture environment of ourprovince, the total chromium and the Cr6 content with greater toxicity in the water quality are smaller, all ofthem are below the limit standard of drinking water sanitation standard (0.05 mg/L), and no cases beyond thefishery water quality standard have been found.
