Personal and Microenvironmental Exposure Measurements

There is strong scientific interest in knowing individuals' total exposure to air pollution from all sources. Personal exposure measurements are considered the most accurate method to characterize total exposure. Microenvironmental measurements and time-activity diaries are often collected in conjunction with personal exposure measurements in order to identify where individuals receive their highest exposures and what sources are most likely responsible for the high exposures. STI staff use the latest measurement technologies and offer personal and microenvironmental measurement services for a variety of gases and particles, including ozone, nitrogen dioxide, carbon monoxide, VOCs, PM_2.5, PM₁₀, and aerosol chemical components.
