本文提出一种有色金属材料LCA定量评价方法--综合比例系数法.该法根据金属元素的环境特征、实际提取冶金过程、社会功能和生物效应等要素,确立了纯金属的环境负荷定量计算原则并求出其相对环境负荷,而后由此计算金属材料的环境负荷比例系数;再根据推导出的模型计算出金属材料的环境负荷定量值.该模型数学原理可靠,公式运用简便.通过对ZL110和ZA8两种不同材料的LCA实例定量评价可知,该法是目前一种能较为客观、地定量计算有色金属材料环境负荷大小的方法.

This paper puts forward an LCA ( Life -Cycle Assessment) quantitative assessment method for non -ferrous metal materials - -comprehensive percentage coefficient method. Based on the elements such as the environmental characteristics, the actual extracting metallurgical process, social functions and biological effects of the metallic elements, this method defines the quantitative calculating principles of environmental load of pure metals and figures outthe relative environmental load, subsequently calculating the percentage coefficients of environment load of the metal materials. It calculates the environmental loading quantitative value of the metal materials again based on the assumed model. This model is reliable in mathematical principle and it is easy to use the formulae. It is known from the LCA example quantitative assessment of the two different materials of ZL110 and ZA8 that this method is an advanced one which calculate objectively the environmental load of the non -ferrous metals at present.
