Lead life cycle was traced based on the concepts of anthropogenic transfer and transformation. Lead transfer and the distribution of chemical species throughout the anthropogenic flow were identified in 2010 in China. The results show that 1.85 Mt lead ore was consumed(besides 1.287 Mt imported concentrated ore and 1.39 Mt lead scraps. After undergoing transformations, 3.53 Mt lead entered end services in chemical species of Pb, Pb O2 and PbSO4, altogether accounting for over 80% of the total lead products. Finally, 2.10 Mt ore was emitted into the environment in such species as PbSO4(26%), PbO(19%) and Pb(15%). Lead transfer begins in primary raw material sectors, and then transfers to manufacturing sectors. Lead provides services mainly in such industrial sectors as transportation, electrical power and buildings or construction.展开更多

Industrial eco-economics is one of the critical branches of eco-economics. It is a subject of objective law of structural upgrading, functional optimization and highly efficient running of industrial eco-economic system, which is combined with industrial economic system and eco-system under the condition of intellectual economy and circular economy combinations. Meanwhile, it is a relatively weak subject in the research field of eco-economics in China for the time being. Taking the practice road of new type industrialization needs the guidance of industrial eco-economics. The modern industrial eco-economics in the 21st century must be adapted to the need of new type road of industrialization in China. The paper analyzes the status quo of research and the main contents of industrial eco-economics and tries to study some key theories of the branch subject.展开更多
