| Abstract: | By using fuzzy mathematics method,the geochemical assessment on environmental quality of air dust near ground in Chengdu economic region was performed according to index-weight determination of element toxicity.The result shows that for cities,the atmospheric environment qualities(AEQ) of cities including Chengdu,Leshan,Meishan are fine,belonging to the first order of clean level;AEQ of Meishan and Yaan fall in the second order of safety level;AEQ of Deyang belongs to the third order of alarm level,which sh... |
