汞

So-called dental amalgams , or fillings made with a mix of mercury and other metals, have been used since the 1800s.

所谓的银汞合金或者是填充材料，是用汞和其他材料混合制成的，这种方法从1800年就使用了。

"Dental amalgams contain mercury, which may have neurotoxic effects on the nervous systems of developing children and fetuses," reads a statement that has been added to the agency's Web site.

&银汞合金含有汞，对于成长中的儿童和胎儿的神经系统具有神经毒性作用，&这一段陈述已被加入到该机构的网站中。

In 1990, dental amalgams made up 67.6 percent of all dental restorations, but by 1999 it was 45.3 percent and, in 2003, an estimated 30 percent.

据ADA 统计，汞的使用在减少。1990年汞牙占牙齿复原的67.6%，但到1999年占45。

Mercury levels of 0.1 micrograms per gram of tissue are considered a threshold of concern for fish-eating mammals, though little research has been done on how different levels of mercury affect mink, otter and related animals.

汞含量0.1微克每克组织被认为是门槛关心鱼类为主食的哺乳动物，但很少有研究已经做了关于如何不同程度的汞影响水貂，水獭和有关动物。

The relationships between Hg concentrations (Hg, mg/kg flesh wt.) and fork length established in both oceans, as Hg=0.0207 FL-1.5542 (r=0.9022) for Atlantic Ocean and Hg=0.0080 FL+0.2186 (r=0.4864) for Indian Ocean, and with a significant difference of slope. It is suggested that different Hg accumulation patterns may exist in different oceans.

两洋区白色肉总汞浓度与尾叉长的直线相关式，分别是大西洋为Hg=0.0207FL-1.5542(r=0.9022)及印度洋为Hg=0.0080FL+0.2186(r=0.4864)，並呈现显著的斜率差异，因而推测不同洋区的剑旗鱼可能存在不同的汞蓄积模式。
