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