Ozone: Chemistry in indoor air and the role of human occupants
Published on Sep 18, 2017
Centre for Healthy Indoor Environments (CHIE, http://www.eat.lth.se/chie/ ) at Lund University in Sweden invited a world-leading expert in indoor air chemistry Prof. Charles J. Weschler from Rutgers University in USA to give seminars and discuss recent research trends in indoor air quality. The first seminar given by Prof. Weschler reviews chemical transformations known to occur in indoor air and on indoor surfaces, and the implications of this chemistry for human occupants.

Dermal uptake directly from air for phthalates and other common chemicals

Centre for Healthy Indoor Environments (CHIE, http://www.eat.lth.se/chie/ ) at Lund University in Sweden invited a world-leading expert in indoor air chemistry Prof. Charles J. Weschler from Rutgers University in USA to give seminars and discuss recent research trends in indoor air quality. The second seminar given by Prof. Weschler describes recent studies with human volunteers that confirm the importance of the dermal pathway for a number of common indoor pollutants. Numerous studies over the past five years have indicated that indoor exposures are responsible for a significant fraction of the plasticizers, flame retardants, surfactants and other additives found in our bodies. Models based on fundamental physical chemistry indicate that some of these compounds are dermally absorbed from air or clothing at rates comparable to or larger than inhalation intake. Yet, with a few exceptions, this pathway has been largely overlooked when performing exposure assessments.
Indoor Chemical Exposures: Humans’ Non-respiratory Interactions with Room Air
Berkley Labs Published on Mar 29, 2010
March 18, 2010 Berkeley Lab Environmental Energy Technology Division distinguished lecture: The marked difference in pollutant concentrations between an occupied and un-occupied room are only partially explained by human bio-effluents. Humans alter levels of ozone and related oxidants such as nitrate and hydroxyl radicals in the rooms they inhabit; in effect, they change the oxidative capacity of room air. Ozone-initiated reactions on exposed skin, hair and clothing generate products, including potentially irritating chemicals whose concentrations are much higher in the occupant’s breathing zone than in the core of the room. Charles J. Weschler is a Professor at the School of Public Health, the Department of Environmental and Occupational Medicine and the Environmental and Occupational Health Sciences Institute (EOHSI) at the University of Medicine and Dentistry of New Jersey (UMDNJ)/Robert Wood Johnson Medical School & Rutgers University (New Jersey). He is also a Visiting Professor at the International Centre for Indoor Environment and Energy, Technical University of Denmark (DTU, Lyngby, Denmark).
Distinguished Lecturer Series: Building Science – Adventures in Building Science Dr. Joseph Lstiburek

As an HVAC professional and perpetual student of building science, I highly appreciated this speech by Dr. Lstiburek, and derived much good info in spite of what some may perceive as caustic delivery from the speaker. Thank you, BerkeleyLab, for making this publicly available on YouTube. It is imperative we get both the envelope and the HVAC system right if we hope to achieve any reasonable measure of 'green' to our buildings.
