The minimum lethal lead dosage making 1.5 mg/kg of the live body weight leads to reduction of its mass recovering after its resoprtion in the stomach. Accumulation and elimination of lead from the body are related to dynamics of the body weight. The rate of these processes is in direct dependence and significantly different in various tissues and organs. Claws, kidneys, liver and feathers are characterized by very high rate of element accumulation and fat, heart and muscles - by the lowest rate. Intense elimination of lead from the body starts approximately in 2-2.5 months after the gastrointestinal tract is released from it.展开更多
