[Discussion on the consistency of detection methods of main indexes of workplace air, ambient air and indoor air].

Major air pollutants include particulate matter, ozone, sulfur dioxide and nitrogen dioxide, etc. Recent posts have confirmed that air pollution has a variety of adverse health effects on people's health.For professional people, because of occupational hazards of these major atmospheric pollutants also exist in the workplace, is likely to suffer from the double hazards of occupational hazards and air pollutants in the workplace, if similar pollutants are present in the home, the daily exposure concentration of the occupational population may be significantly higher than that of the general population. Exposure limits and testing methods for major atmospheric pollutants (particulate matter or dust, ozone, sulfur dioxide and nitrogen dioxide) are set by relevant standards in workplace air, ambient air and indoor air. However, due to different places and different management departments, there are differences in the detection methods of the same indicators, which brings difficulties to estimate the total daily exposure level. The purpose of this paper is to discuss the "consistency" of the detection method of relevant pollutants in the air, in order to provide scientific basis for estimating the daily exposure level of pollutants in different populations.
