重金属

On the basis of analysis on heavy metal content in incineration residue, the source, migration mechanism, distribution in different incineration products and various forms as well as the comprehensive toxity of heavy metals in incineration residue are discussed in this dissertation.

从分析焚烧残渣中重金属含量入手，对炉渣中重金属的来源、迁移机理、各焚烧产物中的分布规律、各形态的分布特性及综合毒性进行了探讨。

The main objective of this paper is to use Cu,Zn,Cd and oxytetracycline, norfloxacin as experimental toxicants and Cyprinus carpio,Carassius auratus Pengzenensis, Trionyx sinensis as as experimental creature, studied the toxicity of copper,zinc,cadmium to the larval carps; accumulations of copper,zinc in the larval carps.

本研究以三种重金属和土霉素、诺氟沙星为实验毒物，以鲤、彭泽鲫和中华鳖为实验动物，研究了铜、锌、镉三种重金属对鲤幼鱼的毒性作用，以及铜、锌在鲤幼鱼中的积累。

Obviously, the chlorinating agents enhanced the volatilization of heavy metals, while sulfur compounds and solid adsorbents changed the evaporation rate in various forms, which may be related to their own chemical reactions and the chemical nature in the high temperature treatment process.

其中氯化剂增强了重金属的挥发特性，而加入硫化合物和固体吸附剂后重金属的挥发特性出现各种形式的变化，这可能与其受热过程中的化学反应及其本身的化学性质有关。

Taking Guixin highway as a case, the pollution state and its change regularity in vertical direction are analyzed, which proves that the heavy mental pollutant enriches within 5m under the ground and decreases towards ground surface but increases near the surface slightly that may have something to do with the convoluting and accumulating effects of tail gas.

文章以贵新路为例，分析了公路边坡土壤重金属污染物的垂向污染状况和变化规律，得出了路坡重金属污染的富集带约分布在距地面5m处，随着高度的增加污染物含量减少，但到了路坡坡顶又出现小幅增高现象，这有可能与汽车尾气卷扬和淀积效应有关。

However, none of them surpass the second-grade criteria, indicating that the translocation of the heavy metals from the gangue damps to their surrounding soils is a slow process.

但矿区土壤中分析的重金属元素均未超过国家土壤二级污染标准，这说明煤矸石中重金属向周围土壤的迁移是缓慢过程。

Accurate delineating of the spatial distribution of soil heavy metal content is essential for pollution assessment and remediation.

准确地描述土壤重金属含量的空间分布对于防治土壤重金属污染是十分重要的。

As the rice furling, Yangdao No.

低浓度的重金属胁迫能明显诱导萌发籽粒中一些淀粉同功酶的表达，而高浓度的重金属胁迫则显著抑制某些淀粉同功酶的表达。

The contents of heavy metals in fly ashes are found to be a function of those in the municipal solid waste incinerated.

迄今为止，飞灰中重金属与垃圾中的重金属含量、形态、熔点和沸点等的关系，尚未完全清楚。

But heavy metal in solidified sludge could be leached again because of Thiobacilli activity in the sludge.

污泥固化后能够降低重金属的浸出风险，但是污泥中硫杆菌的活动存在再次将重金属浸出的可能。

Besides, the leaching rate and the content of heavy medals have no obvious relation.

此外，重金属的渗出率与重金属的含量没有明显的关系。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
