进口铁矿石中有毒有害元素对环境安全影响的研究

Study of the Effect of Poisonous and Harmful Elements of Imported Iron Ores on Environment Safety

通过对从深圳口岸进口的132批铁矿石中有毒有害元素含量的分析,发现进口铁矿石中Pb、Cr、Hg、F的含量水平均在可接受范围内,但部分产地的铁矿石中Cd和As的含量较高,存在不同程度的Cd和As污染环境的风险,尤其是来自南非的铁矿石中有一部分批次Cd和As的含量均较高,存在更大的环境污染风险,应采取适当的控制措施。

To master the content values of poisonous and harmful elements among imported iron ores from different countries, 132 batches of iron ores imported through Shenzhen Port were analyzed. The results showed that the content values of Pb, Cr, Hg and F were acceptable, but the content values of Cd and As in some batches were rather high, indicating to the risk of pollution on the environment to some extent. Especially, the content values of Cd and As in some batches imported from South Africa were rather high at...
