Humans Identified as the Largest Source of Volatile Organic Chemicals in Indoor Air
US researchers found that people and their possessions directly emitted 57% of the volatile organic compounds (VOCs) they measured in the air of a university lecture theatre. We spend approximately 90% of our life inside, where concentrations of VOCs are consistently found to be much higher than in outdoor air. This research is one of the first few to detail the important role that emissions from direct human occupancy plays here.
