基于LCA理论半刚性基层人体健康损害因素分析
|
摘要
采用定额数据结合工程背景,对半刚性基层生命周期过程中排放的污染物进行健康损害因素分析。通过SimaPro软件确定了各阶段污染物排放量、资源、生态和人体健康损害评价。结果表明:排放物过程中的污染物含量,CO_2> NO_2> CO> SO_2> PM;原材料生产阶段污染物排放量占比最高达到37.64%,另外其他阶段损害因素排放负荷不可忽视;原材料和混合料运输过程NO_2占总量的66%,呼吸无机物所造成的损害最大。
Using the fixed data combined with the engineering background,to analyze the health damage factors of pollutants discharged during the semi-rigid base life cycle,the evaluation of pollutant emissions,resources,ecology and human health damage at various stages was determined by Simpro software. The results shows that:pollutant emissions CO_2> NO_2> CO> SO_2> PM;The discharge of pollutants in the raw material production stage accounts for up to 37.64%,and the discharge load of damage factors in other stage cannot be ignored;During the transportation of raw materials and mixed materials,NO_2 accounted for 66% of the total,the damage caused by respiratory inorganic substances is the biggest.
