Community air sampling ranges from simple infrequent measurement of individual pollutants to complex, continuous monitoring of multiple pollutants. To aid in planning a sampling program, suggestions are given with respect to purpose, site, location, sampling frequency, methods, Quality Assurance, and data retrieval. To aid in site selection and/or estimate historical air pollution levels, estimating techniques and their limitations are discussed. Limitations on the use/usefulness of fixed location, outside air monitoring stations are discussed. The need for instrumentation to provide levels of individual ambient exposure is also discussed.
