重金属

One of the stars of the show and this year's third place winner, the clothes drying rack contains no heavy ls, is constructed entirely out of recycled materials and bamboo, and requires no energy to use.

这个获得三等奖的晾衣架不含重金属，完全是再生材料和竹子做成的，也不耗费任何能源。

To solve this problem we have done a lot of analysis tests, the use of solubilizer to increase the solubility of dye; dyeing process using soft water, and add the chelating agent to reduce the sodium sulphate caused by hardness, while improving, but you can not completely avoid the dyeing flowers and subsequently by a large number of trials found that there is a dye bath Fe3 +, Cu2 +, Zn2 +-induced dye accumulation of heavy metal ions such as lead-color flowers.

为解决此问题我们做了大量分析试验，使用增溶剂，增加染料的溶解度；染色过程中使用软水，并添加螯合剂来降低元明粉引起的硬度，虽有所改善，但不能彻底避免染花，后经大量的试验发现是染浴中存在Fe3+，Cu2+，Zn2+等重金属离子诱发染料聚集引起色花。

Heavy metals in soil can be transferred to arthropods through food chains and accumulated in these animals.

土壤中的重金属可通过食物链向节肢动物传递，并在其体内累积。

The influences of bioaccumulation on the ayes on the top of food chains were discussed aiming to provide some inferences for the protection and management of endangered waterfowls.

在此基础上，探讨了重金属元素经食物链产生的生物累积放大作用对位于食物链最高营养级鸟类生存所构成的潜在威胁，从而为珍稀水禽保护及管理措施的制定提供一些依据。

Structural characteristics and sorptive behaviors and mechanisms for heavy metal cations of bentonite are analysed.

分析了膨润土的结构性质和它对重金属离子的吸附机理。

Organisms often synthesize molecular chaperons to cope with stress such as heat, cold, wounding, heavy metals, and water deficit.

生物常合成分子保护子来应对高温、低温、伤害、重金属以及缺水等逆境。

There are some isomeric compounds of hydroxypyridinone. The compounds of 2-hydroxy-6-pyridinone have been used to dyestuff and pesticide widely. The compounds of 3-hydroxy-2-pyridinone and 3-hydroxy-4-pyridinone are paid attention to, because they are very useful heavy metal chelations. Especially, they are wonderful candidate medicament for the toxicosis of depleted uranium, so they can settle the DU jeopardize to the people.

羟基吡啶酮化合物有不同的同分异构体，2-羟基-6-吡啶酮已被广泛用于染料和农药行业，而3-羟基-2-吡啶酮和3-羟基-4-吡啶酮也引起了人们的重视，因为这两种异构体的化合物是非常理想的重金属络合剂，尤其重要的是，它可作为解决贫铀中毒的候选药物，有望解决战争中由于贫铀中毒带来的危害。

The effect of using chelator was better than that of citric acid in heavy metal contamination soil.

结论］在重金属污染土壤上以施用螯合剂EDTA、DTPA为好。

The aim was to study the effects of different chelators on soil enzyme and soil respiration in heavy metal contamination soil.

［目的］研究不同螯合剂对重金属污染土壤酶和呼吸强度的影响。

Wastewater effluent has also caused environmental concerns because it contains high biological oxygen demand, lignins from the trees, and dissolved organic carbon, as well as heavy ls, alcohols, chelating agents, and chlorates.

废水污水也造成环境的关注，因为它含有高生物需氧量，木质素的树木，溶解有机碳，以及重金属，醇类，螯合剂和氯酸盐。

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。
