Indoor Environmental Quality in SchoolsNew Project with R. Corsi, A. Novoselac, Y. Xu (CAEE), S. Wu (Center for Sustainable Development) and S. Horner (School of Nursing)

• High schools ‐ virtually unstudied environments

• Field campaign in 6 high schools • 120+ Classroom visits & selected 

portables• Identifying relationship between health 

symptoms and– Environmental Conditions– Microbiome– Chemical contaminants   

• Integrating community engagement and research

Related Research• Toxicity of fine particulate matter 

(Reactive Oxygen Species in the indoor & outdoor environment) 

• Removal of pharmaceuticals and personal care products from water (with D. Lawler and C. Whitman (School of Pharmacy)

• Harvested Rainwater Quality        (Kirisits, CAEE)

• Removal of algae & P from water     (Katz, CAEE)

Opportunities for Collaboration

• Linking climate change mitigation strategies with protection of human health– Relationship between water/energy conservation measures & human exposure to contaminants

• Exposures:– Viruses– Nanoparticles – Lung Cell

• Links with Public Health Researchers
