如何计算PPM我国大气污染物的三级标准规定日均浓度限值:SO2:0.25mg/m3,NO2:0.15mg/m3,CO:6.00mg/m3,O3:0.20mg/m3,标态下它们各为多少ppm?

如何计算PPM
我国大气污染物的三级标准规定日均浓度限值:SO2:0.25mg/m3,NO2:0.15mg/m3,
CO:6.00mg/m3,O3:0.20mg/m3,标态下它们各为多少ppm?

1mg/m3=1000000ppm

SO2:0.25mg/m3=0.25ppm
NO2:0.15mg/m3=0.15ppm
CO:6.00mg/m3=6.00ppm
O3:0.20mg/m3=0.20ppm
