重金属

So, a lot of fundamental research work needed to be done, including screening Daphnia, as a biomonitor, that is sensitive to toxicant but less to environment changing so as to decrease the environmental interferences for obtaining more accurate determination results; exploring the relationship between the phototactic behavior of Daphnia and pollutants such as nitrogen, phosphate, heavy metal, hormone and pesticide, especially their mixtures; studying the effect of environmental conditions such as temperature, pH and fish kairomones on the phototactic behavior of Daphnia.

口。。。口国。国里华典翩胭角嗓国但由于缺乏有效的研究方法，致使有关研究难于开展，人们不得不忽略有害物质之间的互相作用，把有害物质共同存在情况视为单一存在。因此，研究氮、磷和重金属对水搔趋光行为的影响规律，有益于认识富营养化水体和重金属污染的土壤中污染物之间的相互作用，弄清这些污染元素共存时产生的生物和环境效应，这些研究是治理土壤和水体污染之前必须解决的重大科学问题。

These dumping sites are not only harmful to surrounding ecological environment, but also threaten the health of around residents.Serious aftermath can be resulted by these refuses polluted with heavy metals in dumping sites because of being disorderly pilled. Therefore, evaluation pollution degree of heavy metal in refuses will be beneficial to perform Environmental Impact Assessment of these dumping sites and put forward measures of pollution protection.

它们不仅影响周围的生态环境，而且威胁到居民的身体健康，特别是不少堆存的生活垃圾受到重金属元素不同程度的污染，任意放置可能会产生严重的后果，所以评价生活垃圾的重金属元素污染程度有助于垃圾堆放场的环境影响评价以及污染防治措施的提出。

However, the selenium can relieve the damage to a certain limitation. During the cultivation of Potamogeton maackianus of rich selenium, the situation of heavy metal pollution should be checked in time so as to avoid the damage on fish caused by the heavy metals enriched in the bait.

然而，Se缓解Cd对黄丝草的毒害是有一定限度的，在富Se黄丝草的繁殖过程中，需及时检查重金属污染情况，防止重金属在饵料中的富集，以免造成对渔业的危害。

Dissimilatory Fe oxide reduction under anaerobic condition is a process which is an anaerobic respiration with Fe as the terminal electron acceptor. This anaerobic respiration showed important environmental significances. Dissimilatory Fe reducers can use diverse electron acceptors including many toxic heavy metals and metalloids such as Mn、Cr、Co insides Fe. So these toxic metals were detoxified or were immobilized reductively.

这种厌氧呼吸作用具有重要的环境学和地学意义，Fe还原微生物可利用除Fe以外的许多其它电子受体包括许多有毒重金属和类金属，如Mn、Cr、Co等，从而对这些有毒重金属起到还原解毒或还原固定的作用；还原过程还可促进一些有机污染物的降解； Fe氧化物的还原偶联着Si、P等元素的变化，对提高这些营养元素的有效性发挥着重要作用。

The content of Mn in stems and leaves can account for up to 55%. Scirpus mariqueter can accumulate more heavy metals than Phragmites australis. And the heavy metal contents have se...

植物体内重金属含量一般在冬季富集；芦苇根际沉积物中重金属的含量秋季较低，冬季富集，而海三棱草根际沉积物中Cu、Pb、Mn均在秋季含量较高，Zn、Cr冬季含量最高。

Heavy metal tolerances of root, stem and leaf of Sesbania rostrata were investigated by using callus suspension culture method.

通过悬浮培养长喙田菁愈伤组织，分别研究长喙田菁根、茎、叶各器官对重金属胁迫的反应，并量化各器官的重金属抗性。

I never liked "Helter Skelter" but it definitely was a predecessor to what we now know as Heavy Metal but with less distortion on the guitars.

我一直不喜欢&Helter Skelter&这首歌，但是它绝对是重金属音乐的发展前身，只是它没有像重金属音乐在吉他部分加上这麼重的失真效果。

Regressive analysis showed that there were linearly positive relationships between PC contents and Cd toxicity in E. nuttallii and P. stratiotes L.. It was indicated that PCs could be a promising biomarker for estimating Cd toxicity.

回归分析显示，2种水生植物体内PCs的合成水平与Cd的生物毒性呈现一定的线性关系，表明PCs可作为重金属Cd胁迫的生物标记物指示水体中重金属的毒害程度。

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。
