铅通过胃肠道和呼吸道进入人体后 ,随血流分布到全身各器官和组织 ,其体内动力学和分布具有三室模型的特征 :1室主要是血液 (特别是红细胞 ) ,或许还有某些软组织 ;2室主要是软组织 ,也许还包含某些含骨骼的活性交换部分 ;3室主要是骨骼。成人身体中的铅 90 %以上与骨骼相结合
Lead enters the body through the gastrointestinal tract and the respiratory tract and is distributed with blood flow to various organs and tissues throughout the body. Its kinetics and distribution in the body have the characteristics of a three-compartment model: Room 1 is predominantly blood (especially erythrocytes), and perhaps some Soft tissue; Room 2 is predominantly soft tissue and may also contain some active exchange parts with bones; More than 90% of the body’s lead is combined with bones
