Dr. Sahay Presents White Paper Findings at PAAA 2018 Conference


Montreal, October 7, 2018 Academicians, researchers, experts and industry professionals from the Pan American Association of Aerobiology (PAAA) assembled at Saint Hyacinthe, Canada for Spore Camp Fall 2018 Conference. The meeting’s goal was to present research findings, as well as to learn and share knowledge about sources, dispersal and deposition of airborne biological particles. At the conference, Dr. Rajiv Sahay, Director of EDLab at Pure Air Control Services Inc. presented his findings from the joint CABA white paper entitled “Human Skin Cells: Source of Building Contamination and Odor”.

Dr. Sahay discussed how he and his research team studied over fourteen thousand surface samples, as well as over six thousand air samples, to identify skin cells as a common constituent of indoor particles. He showed data outlining how indoor environmental dust is composed of approximately 75-90% skin cells. These skin cells can reduce the ozone levels within a building, but many times they are identified as a potential source of indoor pollution that can negatively impact the health and comfort of building occupants. Human Skin Cells White Paper Dr. SahayHe also illustrated that these particles are deposited throughout a building's air conveyance system, including the HVAC coils, and that they can affect the health of a building by causing odors or by acting as allergen trigger to occupants.

Finally, Dr. Sahay summarized that mitigation of these particles is important in order to enhance building well being and save energy through improved HVAC performance. Intervention such as good housekeeping practices, use of minimum efficiency reporting value (MERV) rated filters for HVAC systems, and periodical HVAC cleaning utilizing eco-friendly technology such as a steam cleaning are, in combination, an effective approach to minimizing the negative effects of skin cells on the health and hygiene of an indoor environment.
