污染物

In such predicaments, purging compounds can play an important role in managing contamination.

在这样的困境下，清洗化合物在污染物管理上会助你一臂之力。

With the reduction of SOM content and the elevation of contamination concentration, the difference between PHE and PYE decreases gradually, while B［a］PYE exhibits a significant difference from them. This could be attributed to the high lipophilicity and large molecular size of B［a］PYE, which make the molecule of B［a］PYE to be more easier to be held in the nanopores of clay and the dense region of SOM.

不同多环芳烃SPMD辅助解吸率差别很大，随着土壤有机质含量的降低，以及污染物浓度的提高，菲和芘的解吸差异逐渐缩小，而苯并［a］芘与上述2种多环芳烃的差异很大，主要是由于苯并［a］芘具有高度亲脂性，并且分子较大，造成其容易滞留在粘土的微孔及有机质的致密结构中。

The presence of different initial concentration of quinoline had remarkable effects on the biodegradation of 3- or 4- or 6-methylquinoline.

3首次研究了喹啉类有机污染物生物降解过程中的底物间的相互作用，发现喹啉的存在对喹啉衍生物的降解具有重要影响。

Because it is naturally occurring is radon.

1960年发现的一种室内污染物是一个特殊的问题，因为它是自然发生的氡。

Therefore,it is feasible to treat pollutants on-site by aeration and leachate recirculation.

因此，在填埋场进行污染物原位去除是可行的。

By flowing the water in the opposite direction of the workflow, the contaminants are isolated and directed to the drain or recycler.

通过使与工作流反向的水流动，将污染物分离并引入排泄管或者再循环器。

If the ecosan would be developed there, new industries could be promoted and 50-100 thousands of employing opportunities could be created, incidence rate of diseases could be reduced, 560 thousand cubic meters of methane could be recycled, investment of sanitary toilet could be reduced to an acceptable price, i.e., 600-750 RMB yuan per house, ecological agriculture could be developed, and pollutants discharge could be reduced while ecological security could be guaranteed.

若在该区域推广生态卫生，可能产生社会、经济及环境效益如下：带动新兴产业，增加5~10万的直接就业机会；降低疾病感染率；回收沼气56万立方公尺；卫生厕所投入控制在可接受的600~750元户^(-1)；促进生态农业循环；降低污染物排放、保障生态安全。

The certification will show in detail, which contaminants are reduced and to what degree.

证明将详细显示，减少污染物，并且在何种程度上。

The authors investigated the environmental-geological conditions of a certain refuse landfill site in Beijing and the ability of strata to prevent refuse pollution and monitored groundwater pollution by refuse for one consecutive hydrologic year.

通过对北京某垃圾场所处的环境地质条件、地层对垃圾污染物的防护能力的调查及对地下水连续1个水文年的污染监测，用单因子和多因子(综合污染指数和内梅罗污染指数)2种方法，评价了该垃圾场对地下水的污染情况。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
