污染

The accumulative quantity of arsenic in earthworms were relative to the content of arsenic in soil.

说明蚯蚓是土壤中洛克沙胂污染的较好的指示生物。

The initial concentrations of acenaphthene in soils were 35.0 mg/kg.

供试污染土壤中危的起始浓度为35.0 mg/kg。

It has been found that AM significantly reduced acenaphthene content in soils. The degradation rates of acenaphthene in soils with inoculation of Glomus mosseae and Glomus etunicatum were 32 7%-45.2%, increased by 6.8%-9.8% than the control.

结果表明，AM作用下土壤中苊总残留量明显降低；接种摩西球囊霉菌Glomus mosseae或幼套球囊霉菌Glomus etunicatum后，供试两个污染土样中苊总残留降解率达32.7%~45.2%，比未接种对照高

The traditional catalyst used in acetal synthetic reaction is strong inorganic acid.

文摘：缩醛合成反应的传统催化剂为无机强酸，但由于副反应多、腐蚀性强和易污染环境等缺点，其使用受到限制。

In particular, methyl acrylate and ethyl acetate are widely used in industry.

丙烯酸甲酯和乙酸乙酯是工业上常用的有机物质，在生产和使用中产生的废气极易造成环境污染。

How to make full use of acetylene sludge to reduce the pollution?

把电石渣充分利用起来，以减少占地，减少对周围环境的污染？

In this paper, acetylsalicylic acid, cyclohexanone Preparation of micro-content of the experimental design, in different reaction conditions were carried out under analysis to optimize the improvements and chemical experiments on the basis of conventional experimental and micro-experimental comparison, being The experimental results consistent with the premise, fully reflects the micro-chemistry experiments to save time, save the amount of reagents, as well as many advantages such as reducing environmental pollution.

本文阐述了乙酰水杨酸、环己酮微型化制备实验的设计内容，在不同反应条件下进行了对照分析，从而进行优化改进，并就基础化学实验中常规实验与微型实验进行比较，在得到一致的实验结果的前提下，充分体现了微型化学实验节省时间、节省试剂用量、以及减少环境污染等诸多优点。

Pure water is clear, achromaticity, natural water often showing a certain color, which mainly comes from plant leaves, bark, roots, humus and soluble inorganic minerals and sediment, su*ce water polluted by industrial waste water will make the water color extremely complex.

纯净的水是无色透明的，自然水时常呈现出一定的色彩，它主要来源于植物的叶、皮、根、腐殖质和可溶性无机矿事物和泥砂等，地面水受工业废水污染后可使水色变患上极为复杂。

Mae, the new process will reduce the environment pollution ceased by acid mist, improve the work conditions and work intensity.

此外，新工艺还大大减少了传统工艺所带来的环境污染，改善了操作条件，降低了劳动强度，具有显著的社会效益。

Process exhaust main pollution factor is the residue of sulfur dioxide, acid mist and dust, after dedusting equipment after the double-absorption can be achieved discharge standards.

工艺尾气中主要污染因子是残留的二氧化硫、酸雾及粉尘，经过除尘设备两转两吸后，能实现达标排放。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
