United States Air and Energy Engineering Environmental Protection Research Laboratory Agency Research Triangle Park NC 27711 Research and Development EPA/600/S2-91/061 Dec. 1991 vsrEPA Project Summary Evaluation of VOC Emissions from Heated Roofing Asphalt Peter Kariher, Michael Tufts, and Larry Hamel A short-term in-house project to charecterize emissions from a simulated asphalt roofing kettle was performed at EPA/AEERL. Hot asphalt surfacing and resurfacing has been identified as a possible significant source of volatile organic compound (VOC) emissions that may affect human health and contribute to the ozone non-attainment problem. This Project Summary was devel- oped by EPA's Air and Energy Engi- neering Research Laboratory, Research Triangle Park, NC, to announce key find- ings of the research project that is fully documented in a separate report of the same title (see Project Report ordering information at back). The purpose of the study was to col- lect, identify and semi-quantitate as many compounds as possible that are discharged during the open heating of roofing asphalt and relate them to the amount volatilized into the air Types 1, 2, and 3 mopping grade as- phalts were chosen for this study. They constitute more than 90% of roofing as- phalt used Samples of each type of as- phalt were placed in a simulated roofing kettle, heated to predetermined tempera- tures, and sampled for volatile and semi- volatile organic emissions. Compounds identified during this study were alkanes, aromatics, a ketone, and an aldehyde. ------- P. Kariher, M. Tufts, and L Hamelare with Acurex Corp., Research Triangle Park, NC 27709. Bobby E.
