代谢
镉可以通过口腔、吸入和皮肤途径被吸收。镉最初与金属硫蛋白和清蛋白结合,并主要运输到肾脏和肝脏。当镉的浓度超过了可用金属硫蛋白的量时,就会观察到毒性效应,而且已经证实镉-金属硫蛋白复合物可能具有损害性。镉不为人所知地经历任何直接的代谢转化,并以原形排出,主要在尿液中。
Cadmium is absorbed from oral, inhalation, and dermal routes. Cadmium initially binds to metallothionein and albumin and is transported mainly to the kidney and liver. Toxic effects are observed once the concentration of cadmium exceeds that of available metallothionein, and it has also been shown that the cadmium-metallothionein complex may be damaging. Cadmium is not known to undergo any direct metabolic conversion and is excreted unchanged, mainly in the urine. (L6)
