In the air we breathe there are countless airborne chemicals that present known or suspected health hazards. Some examples include chemicals from fossil fuel burning in power plants and automobile exhaust, volatile organics from oil and gas production, other industrial releases, agricultural pesticides, flame retardants embedded into common textile products, in addition to other sources.
Prior to the introduction of MyExposome technology, the "grab sample" method was frequently used to measure airborne contamination. This approach used samples of air from a single place and time which is expensive when multiple samples are required to track airborne contaminants. Sampling static environments using this method is inherently periodic and can miss important exposure events, resulting in incomplete measurements to assess cumulative exposures. Additionally, stationary "grab samples" may not represent complex environmental exposure as accurately as a personal monitoring device.
