南宁５０ 名非职业性接触铅镉的女性，血液中铅镉含量分别为６８８０μｇ／ Ｌ（ Ｐｂ） 和１２５μｇ／ Ｌ（ Ｃｄ） ，人均通过空气和饮食摄入铅５０２０μｇ／ 日，镉２５３８μｇ／ 日。环境中空气和食物的铅暴露水平，对机体血铅含量的影响具有同等重要的作用；机体中镉主要来自环境中的食物，它占人均每天镉总摄入量的９４０ ％ ，空气镉的摄入量是十分微少的。
A total of 50 non-occupational women exposed to lead and cadmium in Nanning had a lead and cadmium content of 6880μg / L (Pb) and 125μg / L (Cd) respectively. Per capita intake of lead by air and diet was 5020μg / day , Cadmium 25 38μg / day. The exposure of air and food to lead in the environment has an equally important effect on the blood lead level in the body. Cadmium in the body mainly comes from the environment, which accounts for 94.0% of the total daily intake of cadmium per person. Cadmium in the air The intake is very small.
