Ambient Air Quality Research Networks

Exposure to trace gases and particles in ambient air is often an important contributor to total air pollution exposure. STI scientists are experts in the design, implementation, and operation of ambient air quality monitoring networks. Our network design experience extends over 30 years and covers criteria air pollutants, acid precipitation, and air toxics. STI scientists have extensive experience enhancing routine air monitoring networks in a cost-effective manner to address exposure assessment research objectives. STI services range from augmentation of existing networks to implementation of relatively large (10 to 20 station) networks. Current capabilities include continuous monitoring of ozone, NO, NO₂, NO_y, CO, SO₂, VOCs, polycyclic aromatic hydrocarbons, sulfate, nitrate, organic carbon, elemental carbon, PM_2.5 mass, PM₁₀ mass, and particle number, size, and light-scattering. Additional capabilities include filter-based integrated sampling for ozone, NO₂, VOCs, SVOCs, PM_2.5 mass, PM₁₀ mass, sulfate, nitrate, ammonia, ammonium, organic carbon, elemental carbon, trace elements, endotoxins, pollens, and spores.
