EPA PROJECT SUMMARIES

The following are several-page, detailed synopses of key findings of projects supported by the U.S. EPA, available at no charge from its Center for Environmental Research Information (CERI), 26 W. Martin Luther King Dr., Cincinnati OH 45268 (513-569-7562). Order full reports (same title and same EPA number without the "S") from NTIS. CERI issues publications announcements several times a year listing new project summaries.

Item #d90jun71

Sensitivity of a Regional Oxidant Model to Variations in Climate Parameters (EPA/600/S3-89/068), R.E. Morris et al. (Systems Applic. Inc.), 5 pp., Sep. 1989. Full report NTIS: PB89-224 943/AS; $21.95.

Ozone concentrations predicted by a complex model using current atmospheric chemistry are sensitive to the climate change scenarios studied. Results suggest potentially significant increases in photochemical pollutants due to future climate changes.

Item #d90jun72

N₂O Field Study (EPA/600/S2-89/006), R. Clayton et al. (Acurex Corp.), 4 pp., Aug. 1989. Full report NTIS: PB89-166 623/AS; $15.95.

N₂O levels were determined on-line at three coal-fired utility boilers and compared with samples collected in stainless steel containers. Results showed no apparent differences related to different boiler types and load conditions.

Item #d90jun73

Potential Technologies for Collection and Destruction of CFCs, Halons, and Related Compounds (EPA/600/S2-89/037), K.E. Hummel, T.P. Nelson (Radian Corp.), 3 pp., Aug. 1989. Full report NTIS: PB89-219 968/AS; $15.95.

A multi-disciplinary panel of experts reports on new and modified technologies and identifies those that are the most promising. Suggests general areas of research and development needed to develop collection and destruction technologies.

Item #d90jun74

Technologies for CFC/Halon Destruction (EPA/600/S7-89/011), J.C. Dickerman (Radian Corp.), T.E. Emmel et al., Oct. 1989. Full report NTIS: PB90-116955/XAB; $15.95.

Key findings address the ability of the various technologies to effectively destroy CFCs and halons, the environmental consequences of such destruction, the ability of current emission monitoring systems to verify that the CFCs have indeed been destroyed, the impacts of current regulations on CFC destruction, and the existence of any significant data gaps.

Item #d90jun75

Evaluation of Refrigerant from Mobile Air Conditioners (EPA/600/S2-89/009), L. Weitzman (Acurex Corp.), 4 pp., June 1989. Full report NTIS: PB89-169 882/AS; $15.95.

Examined 227 cars to evaluate the quality of refrigerant from air conditioners in cars of different makes, ages and mileages from different parts of the country, with both failed and properly working air conditioners. Refrigerants were found to be pure with no acid accumulation. Concludes that CFC-12 does not degrade significantly with use.
