Atmospheric contaminants are ubiquitous and have a profound impact on ecosystem and human health. Environmental and health related costs are high with 87% of the global population living in areas with pollution exceeding WHO recommendations, and 10% of global deaths being attributable to air pollution1.

While long term data for established critical air pollutants are readily available, considerable gaps have opened up in the identification, photochemical conversion, transport and impact of poorly characterized (e.g., reactive gaseous mercury) and emerging species (e.g., ultrafine aerosols, biogenic toxins, SVOCs).

Using examples of compounds of anthropogenic and biological origin, Dr. Kos will demonstrate how organics, heavy metals and SVOCs can be assessed using mass spectrometric, spectroscopic and modeling techniques to study local effects, global transport, and health impacts.

Dr. Kos will also highlight how pollutants and their conversion products are tracked from source to sink and propose strategies to address knowledge gaps, such as the assessment of local air pollution and transport modeling results.
