Author Interviews, Environmental Risks, Exercise - Fitness / 09.01.2021 Interview with: Zach Finewax, PhD Research Scientist I Cooperative Institute for Research in Environmental Sciences (CIRES) National Oceanic and Atmospheric Administration (NOAA) Chemical Sciences Laboratory (CSL) Chemical Processes and Instrument Development (CPID) University of Colorado, Boulder, CO What is the background for this study? gym-exercise-sweat.jpegResponse: Humans on average spend 90% of their time indoors. As a result, they are exposed to indoor air far more often than outdoor air (the atmosphere). Yet, the chemistry (and air quality) of the atmosphere has been studied far more often than indoor air. Air quality is linked to direct health impacts, and the emissions indoors can be ventilated outdoors where they can undergo chemical transformations that have climate and health impacts. Beyond exposure to indoor air, humans contribute significantly to overall indoor air quality by breathing, sweating, and applying personal care or hygiene products. Previous studies have investigated these emissions at a high level of chemical detail for seated or standing individuals indoors, but limited chemical and time-resolution studies have been conducted while people are exercising indoors.

Author Interviews, Environmental Risks, Microbiome, Pediatrics, Weight Research / 20.09.2018 Interview with: Anita Kozyrskyj PhD Professor in Pediatrics Faculty of Medicine & Dentistry School of Public Health University of Alberta What is the background for this study? Response: Data for this study were collected in the Canadian Healthy Infant Longitudinal Development (CHILD) cohort of over 3,500 full-term infants born between 2009 and 2012. When infants were 3-4 months of age, parents provided a sample of their poop. At that time, parents checked-off responses to questions about their home, including type and frequency of cleaning product use. The infant poop was initially frozen, then thawed later to extract DNA from the sample and identify microbes on the basis of their DNA sequence.  (more…)
