A major new study has found that personal-care products, paints, indoor cleaners and other chemical-containing agents are the increasingly dominant sources of air pollution. Conducted by scientists from the National Center for Atmospheric Research, and universities in the United States, Canada and South Korea, and published in the journal Science, the study looked at products that release volatile organic compounds, or VOCs, petroleum-based substances that can contribute the formation of ozone and small-particulate pollution one released to outdoor air. According to the study, the contribution of these chemicals to the levels of VOCs has been significantly underrepresented in inventories for sources of pollution, and as the transportation sector becomes cleaner, the sources of air pollution of becoming more diverse. For example, VOCs can take a variety of forms and have complicated origins, and are released by trees and grass, as well as from cars, consumer and industrial products like pesticides, coatings, printing inks, adhesives, cleaning agents, and personal care products.
