ABSTRACT
The quantification of pollutant mass is primarily the job of the analytical laboratory or of the lab personnel. The quantification of the volume of gas sampled, however, is the job of the air sampling or field personnel. The air sampling refers to five distinct sampling categories: source or emission sampling, ambient sampling, industrial hygiene air sampling, residential indoor sampling, and process or quality control. Air sampling, the collection of a sample for later analysis, has become a good deal due to three developments: widespread awareness of the dangers of even small quantities of organic or other toxic pollutants in the air. It also include: the development of toxic air pollutant regulations by state air pollution control agencies, under the guidance of the Environmental Protection Agency and the development of highly sophisticated laboratory techniques for measurement of minute quantities of pollutants collected from air or exhaust gas streams.
