air Pollution sampling

Description

The document discusses air pollution and methods for sampling air pollutants. It defines pollution and lists major sources of outdoor air pollution such as vehicles, power plants, and waste burning. It describes common air pollutants like particulate matter and gases. The document then discusses air sampling methods for particulate and gaseous pollutants using techniques like sedimentation, filtration, impingement, and adsorption. Specific instruments are mentioned like bubblers and impingers for liquid collection and activated carbon for gas adsorption. Spectrophotometry, chemiluminescence, UV fluorescence, and gas chromatography are also summarized as analytical methods for measuring gaseous pollutants.
