Air Monitoring Methods -
Passive air samplers are inexpensive compact, portable air pollutant sampling devices. They are ideal for determining base-line concentrations and as a survey tool. They are ideal for assessing personal and environmental exposures over time frames generally ranging from one day to two weeks. Exposure times as short as 8 hours and as long as one month are achievable under requisite concentration conditions.
