代谢
接触钍可能发生在吸入、摄入或皮肤接触之后。一旦进入人体,钍主要在肝脏、脾脏、淋巴结、肺和骨骼中积累。转铁蛋白在钍的运输和细胞摄取中起着主要作用。钍可能与氧结合形成Thorotrast(钍二氧化物),这是一种可能影响蛋白质摄取的胶体。钍和Thorotrast主要通过粪便排出。(L1838)
Exposure to thorium can occur following inhalation, ingestion, or dermal exposure. Once in the body thorium accumulates mainly in the liver, spleen, lymph nodes, lungs, and bone. Transferrin plays a major role in the transport and cellular uptake of thorium. Thorium may combine with oxygen to form thorotrast (thorium dioxide), a colloid which may affect protein uptake. Thorium and thorotrast are excreted mainly in the faeces. (L1838)
