国内外有关海洋生物重金属的报告很多,但一般所涉及的生物种类与测定的样次都非常有限,很难达到统计学处理的数量要求。因此,要比较科学地探明重金属在海洋生物中的含量变化规律是困难的。我们对南海海洋生物的重金属含量进行了长期而广泛的调查,从种类与数量上看,据不完全统计,取得了包括67科171种鱼类、8科21种甲壳类、23科60种软体动物以及棘皮动物中的海参和海洋植物中的紫菜等1496个生物样品的调查数据,本文将对这些调查资料进行统计学处理,并在此基础上提出初步的分析结果与应用意见。
There are a lot of reports on heavy metals in the world at home and abroad, but the types of organisms and the types of determination generally are very limited and it is difficult to meet the quantitative requirements of statistics. Therefore, it is difficult to scientifically ascertain the variation rule of heavy metals in marine organisms. We conducted a long-term and extensive survey of the heavy metal contents of marine organisms in the South China Sea. According to incomplete statistics, there were 67 families of 171 species of fish, 8 families of 21 species of crustaceans, 23 families of 60 species of software Animal and echinoderms seaweed and marine plants of seaweed and other 1496 biological samples of the survey data, this article will conduct a statistical analysis of these survey data, and on this basis, put forward preliminary analysis results and application views.
