Conclusion As compared with foreign countries,PbB in China was low in the early days of the eighties,but in the nineties was moderately high.The change of CdB was not significantly in the period of 1981~1998.As compared with foreign countries,CdB in China is moderately high both in the early days of the eighties and now.
