摘要

汞(Hg)的毒理学令人担忧,因为这种金属在环境中无处不在,生物体经常接触到低浓度到高浓度的汞。人们对汞的毒性作用进行了深入研究,发现汞的化学种类不同,毒性作用也会不同。在本章中,我们将强调汞在大脑发育过程中对神经的毒性作用。未成熟的大脑更容易受到汞暴露的影响,因为所有形式的汞化学物质,而不仅仅是有机汞,都会对大脑造成伤害。本章将讨论在发育早期阶段接触汞可能产生的后果、与其他同时存在的神经毒物的叠加效应,以及已知的作用机制和靶点。

Neurodevelopmental Effects of Mercury.

Neurodevelopmental Effects of Mercury.

The toxicology of mercury (Hg) is of concern since this metal is ubiquitously distributed in the environment, and living organisms are routinely exposed to Hg at low to high levels. The toxic effects of Hg are well studied and it is known that they may differ depending on the Hg chemical species. In this chapter, we emphasize the neurotoxic effects of Hg during brain development. The immature brain is more susceptible to Hg exposure, since all the Hg chemical forms, not only the organic ones, can harm it. The possible consequences of Hg exposure during the early stages of development, the additive effects with other co-occurring neurotoxicants, and the known mechanisms of action and targets will be addressed in this chapter.
