The GreenHome Institute’s – “Chemical Product Emissions Emerging as Urban VOCS” – Free CE Webinar
September 22, 2021 @ 12:00 pm - 1:00 pm EDT
Details about this event
Over multiple decades volatile organic compound (VOC) emissions from the transportation sector have decreased by over an order of magnitude. As transportation emissions decline, other sources of urban VOCs are likely growing in relative importance. This talk focuses on emissions from the everyday use of volatile chemical products (VCPs), including personal care products, cleaning agents, inks, coatings, adhesives, and pesticides. Most of the emissions occur indoors and then are transported to the outdoor atmosphere, which then undergo chemical processing in the atmosphere and degrade air quality through the formation of ground-level ozone and fine particulate matter. In the Los Angeles basin, we estimate that VCPs now account for around half of the petrochemical VOCs emitted. Follow-on measurements in New York City with ground-based and mobile laboratory platforms also indicate that VCPs are important sources of anthropogenic VOCs, and also suggest the importance of indoor emission sources on outdoor air quality. We will discuss chemical tracers that can be used to detect with greater chemical specificity the types of chemical products emitted into the atmosphere, as well as modeling showing how different chemical products affect the formation of urban air pollution.
