Finally, industrial policy for sulfuric acid industry in China is given: using reasonably both international and domestic sulfuric sources; developing vigorously and steadily the process of sulfuric acid production from sulfur; enhancing recovery and utilization of effluent gases from non-ferrous metal smeltery and combination sulfuric sources with non-ferrous metal mine; maintaining production capacity and output with iron pyrite as raw material; strengthening home-built work for large-scale sulfuric acid plant.

最后阐述我国硫酸工业的产业政策：合理利用国际，国内两种资源，积极稳妥地发展硫磺制酸；加强冶炼烟气制酸和有色金属伴生硫资源的回收和利用；稳定硫铁矿制酸能力和产量；加强大型硫酸装置国产化工作。

A geostatistical method was put forward to analyse the spatial variability of combined heavy metal pollution in soils based on GIS. The spatial analysis showed a combined Cu and Cd pollution occurred in the research area, Cu was mainly concentrated in surface layer, but Cd had high concentrations in 0-60cm depth of soil profile. The correlation analysis revealed that the point source pollution was dominated by the pollution let-out of the smeltery.

研究首先建立了基于GIS的地统计学采样和分析方法的步骤，然后着重分析了土壤铜镉复合污染的空间变异特征和影响因素，发现研究区土壤铜镉复合污染为点源污染类型，铜在土壤中具有明显的表聚性，而镉容易迁移，在0-60cm的土层中均形成污染，同时土壤的复合污染已经在水稻籽粒中引起污染物超过食品食用标准。

Phytoremediation is an effective measure to eliminate heavy metals, contaminants from soils,, an experiment was carried Out during March-Dec. 2004, on effect of a green manure crop, Chinese milk vetch (Astragalus siniucus L.) in a field of heavy metals contaminated soil in the vinicity of a smeltery in Guixi City of Jiangxi Province.
