污染

Today concern for the environment extends into such areas as chemical pollution of the air we breathe and the water we drink ,strip mining,dam and road building ,noise pollution ,offshore oil drilling ,nuclear energy ,waste disposal, the use of aerosol cans and nonreturnable beverage containers and a host of other issues.

今天对环境的关注已经延伸到这样一些领域，像是我们呼吸的空气和我们喝的水的化学污染，露天采矿，大坝和公路建设，噪音污染，近海石油钻探，核能源，废物处理，喷雾器皿和不能回收的饮料包装的使用和其他大量的问题。

今天，环境问题已扩大到了下列领域：人们呼吸的空气和饮用的水之化学污染、露天采矿、堤坝和道路之修建、噪声污染、近海石油钻探、核能、三废处理、溶胶罐和不回收饮料容器之利用和一系列其它问题。

The soil urease and invertase activity effected by Hg was investigated in different fertility soils. The results show that soil urease activity、maximum reaction velocity (Vmax、Vmax/Km) and reaction velocity constant k have remarkably negative correlation with Hg concentration so that these can be used as ecological indexes of soil polluted by Hg, Km changes a little indicating that the reaction mechanism of Hg and urease is nonreversible competitive restraint. Urease of low soil fertility is more damaged by Hg than that of high soil fertility, with severe pollution at Hg concentration of 6.00 and 14.79mg/kg respectively; while invertase is less sensitive to Hg than urease. Cultural time has less influence on the relationship of soil enzyme and Hg concentration.

对不同肥力土壤脲酶和转化酶活性受汞影响进行了研究，结果显示，土壤脲酶活性、最大反应速度Vmax 、Vmax/Km和反应速度常数k与汞浓度呈现显著或极显著负相关关系，表明其可作为土壤汞污染的生态指标；米氏常数Km则变化较小，表明汞与脲酶作用机理为不可逆竞争抑制；低肥力土壤脲酶比高肥力土壤脲酶受汞毒害作用更强，当汞浓度分别为6.00和14.79mg/kg时即达到严重污染；而转化酶对汞的敏感性较差；培养时间对土壤酶与汞浓度间关系影响较小。
