Research Highlights:
Identified phthalates, organophosphates and cyclic siloxanes in indoor airborne particles (early ’80s).
Identified certain reactions catalyzed by transition metals as sources of free radicals within aqueous atmospheric aerosols (mid ’80’s).
Early assessment of indoor ozone exposures showing that they are often comparable to or larger than outdoor exposures (late ’80s).
Demonstrated substantive impact of ozone-initiated chemistry on indoor environments (early ’90s).
Outlined circumstantial evidence for meaningful levels of nitrate radicals indoors (early ’90s).
Predicted, and later confirmed, significant indoor levels of hydroxyl radicals from ozone/terpene reactions (mid 90s).
Called out broad influence of indoor chemistry and suggesting areas for future research; follow-up reviews at 7-yr intervals (mid ’90s).
Identified ozone/terpene chemistry as a strong indoor source of secondary organic aerosols (late ’90s).
Recognized the potential adverse health effects of ozone reaction products indoors (mid ’00s).
Critically reviewed indoor pollutants, primary & secondary, resulting from the use of cleaning agents and air fresheners indoors (mid ’00s).
Discovered the importance of ozone/skin oil chemistry as a sink for ozone and a source of oxygenated organics in occupied environments (late ’00s).
Cataloged the changing nature of the chemicals found indoors over the past 50 years (late ’00s).
Presented a physical-chemistry based framework for better understanding of SVOC dynamics in indoor environments (late ’00s).
Demonstrated that city-to-city differences in indoor exposures to outdoor ozone partially explain city-to-city variability in short-term mortality coefficients associated with ozone; similarly for PM10 (early ’10s).
Identified dermal absorption, directly from air, as a significant exposure pathway for certain indoor organic pollutants (early ’10s).
