Volatile chemical products emerging as largest petrochemical source of urban organic emissions

Volatile chemical products emerging as largest petrochemical source of urban organic emissions | Atmospheric Chemistry | Scoop.it
Transport-derived emissions of volatile organic compounds (VOCs) have decreased owing to stricter controls on air pollution. This means that the relative importance of chemicals in pesticides, coatings, printing inks, adhesives, cleaning agents, and personal care products has increased. McDonald et al. show that these volatile chemical products now contribute fully one-half of emitted VOCs in 33 industrialized cities (see the Perspective by Lewis). Thus, the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted.
