8、04质量百分浓度 5、ppm是重量的百分率，ppm=mg/kg=mg/l 即:1ppm=1ppm=1000ug/l 1ppb=1ug/l=0.001mg 式中：e溶质的克当量； d溶液的比重； m溶质的摩尔质量；            体积浓度是用每立方米的大气中含有污染物的体积数（立方厘米）或（ml/m3）来表示，            常用的表示方法是ppm，即1ppm=1立方厘米/立方米=1

9、0-6。除ppm外，还有ppb和ppt，            他们之间的关系是：              1ppm=10-6=一百万分之一，            1ppb=10-9=十亿分之一 ，
