重金属

Low molecular organic acids are commonly present and become an important factor in affecting transformation and transfer of heavy metals in environment.

低分子有机酸普遍存在于自然环境中，其与重金属阳离子的螯合作用是环境中重金属迁移转化的重要影响因素。

Nowadays there are people, who think heavy metal is the music for Satanists and no-lifers, but back in the middle ages, the tritone is considered evil and it is in fact declared as the music you play to summon the Beast.

现在有人还认为重金属音乐是为那些邪教信徒和那些认为生命没有意义的人所'创作'的，而这些人这样批评重金属音乐，是因为他们觉的这个音乐听起来非常的'邪恶'。

For some kinds of vegetables and pasturages, the contents of some heavy metals surpass the relevant quality standards, so when some crops were planted on the substrates, the uneatable species should be selected preferably and if some kinds of vegetables and pasturages must be adopted, the output could not be provided to mankind and also not be used in farming, in order to avoid harming peoples'health.5 The expediency evaluation model of pioneer plant on substrates was established and some plants were studied. The results show that the expediency evaluation of pioneer plants were respectively that clover was expedient to substrate 1, juniper, cotton and fescue were expedient to substrate 2 and juniper, annual bluegrass, fescue, cotton and clover were expedient to substrate 3.6 Some indexes to evaluate the capability of the phytoremediation on heavy metals and the comprehension about hyperaccumulator were put forward.

有多种植物的重金属含量超过了相应的国家标准，因此在基质上种植植物时，尽量选择非食用性植物品种，即使种植了蔬菜和牧草等植物，也不应将收获后的产品供人类食用或用于畜牧生产，以免危害人体健康。5建立和研究了复垦基质先锋植物的适宜性评价模型，结果表明，不同基质中适宜的先锋植物分别如下：基质1为苜蓿，基质2为桧柏、棉花和高羊茅，基质3为桧柏、早熟禾、高羊茅、棉花和苜蓿。6探讨了评价重金属元素植物修复能力的指标体系和"超富集植物"的概念。

Heavy metal-PC chelatins are subsequently transported from the cytosol to the vacuole and heavy metal detoxification is thus achieved.

在植物体内植物络合素可与重金属螯合，并进一步转运至液泡储存，使细胞质的重金属浓度降低，从而达到解毒效果。

The muffle kiln was also used in the experiment of calcining of MSWI fly ash. This study investigated the migration characteristics of 4 heavy metals in the process of calcining and established vaporescence kinetics models of heavy metals.

其次，采用高温箱式电炉对垃圾焚烧飞灰进行煅烧实验，对高温煅烧过程中4种重金属(Cd、Cu、Cr和Zn)挥发动力学展开研究，建立煅烧过程每种重金属挥发反应动力学模型。

Vetiver grass can grow well in the same concentrations of heavy metals-contaminated soil, and the growth was not affected by the toxicity of heavy metals. The concentrations of Cd and Zn in the shoots of vetiver grass were 40.7±8.28 and 1,399±132 mg/kg, respectively, and no Pb was detected.

培地茅则可以在相同重金属污染土壤中生长良好，并没有受到重金属的影响而产生毒害症状，植物体地上部中镉及锌浓度分别约为40.7±8.28及1，399±132 mg/kg，而铅浓度则未能检出。

The accumulation of heavy metals in the tissues from high to low is viscus, gills and muscle.

在自然界中，重金属污染往往是多种金属的复合污染，在2种重金属离子之

O the soil surfaces due to the less proportion of the activable forms. The results of species analysis also indicated that human activities not only led to higher accumulation of some heavy metals, but also induced the increase of their mobility and bioavailabily, which caused a greater ecological risk by these heavy metals.

矿区土壤重金属元素的生物有效性系数结果表明，重金属中Cd、Mn的生物有效性系数最高，Co、Pb、Zn的生物有效性系数次之，Cu的生物有效性系数最低，说明Cd、Mn元素的生物可利用性强，由此带来的环境危害也较大。

By using fluorescence spectrophotometry method,a systematic study was conducted to determine the effect of cadmium and lead ion stress on reactive oxygen species in creeping bent Agrotis stolonifera leaf tissue.

通过2种重金属离子和抗霉素A处理匍匐翦股颖Agrotis stolonifera幼苗叶片，利用2，'7'-二氯荧光黄双乙酸酯溶液对重金属胁迫和抗霉素A处理后叶片中产生的过氧化氢(H2O2)反应形成具荧光物质DCF的特性，用荧光光度分析法分析了叶片中H2O2产生与积累规律。

The results of study on enrichment of heavy metal Pb2+ in water show that the water can be purified by Alternanthera philoxeroides.

水花生对水体中重金属Pb2+的富集作用研究表明，重金属Pb2+浓度为5mg／L，pH为7.0-8.0 (pH为7.5最佳)，处理温度为25℃-30℃(温度25℃最佳)时；在处理时间为7d以后，水花生净化Pb2+可以达到低于国家标准所允许排放的最高浓度0.2mg／L

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。
