开发利用煤炭释放出的汞是否可能污染环境,这是人们关注的问题。采用AMA254汞分析仪对淮南煤田的35件煤样品中的汞含量进行了测定,结果表明淮南煤中的汞含量处于国内外多数煤中汞的一般含量范围之内,没有出现汞的异常富集现象。据现有资料,开发利用淮南煤尚不至于产生汞污染问题。但是汞毕竟是煤中有害元素,对煤中汞,以及发电厂燃煤释放出的汞进行经常性监测还是必要的。
Development and utilization of mercury released by coal is likely to pollute the environment, which is a matter of concern. The mercury content of 35 coal samples from Huainan coalfield was determined by AMA254 mercury analyzer. The results showed that the mercury content in Huainan coal was within the range of the general content of mercury in most coal at home and abroad, and there was no abnormal enrichment of mercury phenomenon. According to available information, development and utilization of Huainan coal is not yet to produce mercury pollution problems. However, after all, mercury is a harmful element in coal and it is necessary to regularly monitor mercury in coal and mercury released from coal burning in power plants.
