结合Zn-Mn电池汞含量的标准制定和变迁过程,对Zn-Mn电池中汞的使用量进行分析,阐明近十年来废旧Zn-Mn电池载汞量与载汞量变化趋势,为评价废旧Zn-Mn电池累积过程的资源性与潜在危害性提供参考。%In order to evaluate the effect of used Zn-Mn batteries contained mercury on the environment around us,this article is reviewing the policy of limiting mercury and Zn-Mn battery output from 1998 to 2007 and the number of batteries as well as their mercury amount were collected and calculated.The result showed that there were more than 40 million tons used batteries around us and these batteries contained more than 80000 kg mercury in them.Further more there was a bottle-neck factor in the process of recycling used Zn-Mn batteries which was not easy and economical to collect them because of more than 97 % used batteries were lost in environment and researchers pay little attention to the lost batteries and their hazardous till now although they had been doing much work on the recycling of used batteries.
