猪场周围环境中砷的分布及迁移规律研究

为了解猪场周围环境中砷含量及迁移规律,对广东省5个典型猪场周围的土壤、植物、水和鱼的砷进行了检测。结果表明,土壤砷均未超标,但含量有升高趋势;植物中的蔬菜砷超标率为100%,其中67%为重污染;水中的砷超标率为66%,为轻污染;鱼肉中砷的检出率为100%,其中超标率为67%。说明猪场周围环境中砷污染严重,且从环境向生物体富集。

Study on the Distribution and Migrating Disciplinavian of Arsenic around the Pig Farm

In order to find out the current situation of arsenirc pollution around the swine farms, the samples of soil, plant, water and fish are collected from five typical pig farms in GuangDong province. The result indicates that the arsenic in soil doesn't exceed the enviromental standard but the content has a rising trend; The rate of exceed quota in vegetable is 100 percent, in which 67 percent is seriously polluted. The rate of exceed quota is 66 percent and 67 percent respectively. It concluded that arsenic not only has polluted the environment around the swine farm, but also removed to other organisms and accumulated in them.
