| 摘 要： | 应用物质流动分析方法,分析2010年铅的环境排放现状。结果表明,2010年国内每消费1 kg精铅就有0.48 kg铅排放到环境中。2010年从人为循环中排放到环境中的铅共计1.89×106 t,主要来自使用阶段(39.20%)和管理回收阶段(33.13%)。量化了1960-2010年人为循环中铅的排放和环境累积,结果表明,这段时期内排放到环境中的铅累积总量为19.54×106 t,按现有人口及国土面积分别折合为14.26 kg和2.04 g/m2.

| Abstract: | Substance flow analysis was applied to analyzing the lead emissions in 2010. It turns out that in 2010, for every 1 kg of lead consumed, 0.48 kg lead is lost into the environment. The emissions in 2010 were estimated to be 1.89×10^6 t, which were mainly from use （39.20%） and waste management＆recycling （33.13%）. The accumulative lead in 1960-2010 from the anthropogenic flow was estimated and the results show that the total accumulative lead in this period amounted to 19.54×10^6 t, which was equivalent to 14.26 kg and 2.04 g/m^2 at the present population and territory. |
