NSF Seeks to Increase Participation of Women in Science Careers In J u n e of this year the National Science F o u n d a t i o n (NSF) announced 23 awards, totaling over $1 million,

aimed at increasing the n u m b e r of women in scientific and technical fields, and a t improving the status of women who are already in science b u t underqualified for some of the better jobs. W o m e n presently comprise only a b o u t 10% of the scientific and engineering work force. T h e awards, made annually under N S F ' s W o m e n in Science program, will s u p p o r t 17 science career workshops and six science career facilitation projects. Science career workshops will advise women how to prepare for careers in science and engineering and present information a b o u t job opportunities. About 3000 women are expected to participate in the one- or two-day workshops, including u n d e r g r a d u a t e and graduate women, as well as women who hold at least a bachelor's degree in a technical area b u t who are unemployed or underemployed in their fields. T h e six science career facilitation projects will provide training to about 265 women with at least a bachelor's degree in science, m a t h e m a t i c s , or engineering, who are not employed in technical fields or are underemployed considering their potential. T h e women will receive 12 to 24 m o n t h s of special training designed to p r e p a r e t h e m to enter the job m a r k e t immediately or go directly to graduate school. T h e American University in Washington, D . C , for instance, will conduct a project in toxicology which will prepare women for jobs in industry and government in such areas as environmental protection, occupational safety, consumer product safety, and disease control.

EPA Solicits Grant Proposals In a booklet entitled " E P A and the Academic C o m m u n i t y " the Environmental Protection Agency describes the research projects of greatest relevance to its goals and mission. A number of the projects involve analytical chemistry and m e a s u r e m e n t science. In the area of pollution control processes, for instance, current priority concerns include the assessment of fuels and combustion processes to identify techniques t h a t can be used to reduce the formation and emission of pollutants, such as polycyclic organic c o m p o u n d s . Program elements include the analysis of fuels to identify potentially mutagenic and carcinogenic fractions, and the development of techniques to separate such fractions from fuels prior to processing or combustion. Another concern in the area of pollution control processes is the identification of pollutants from synthetic fuels processes, such as oil shale retorting, coal liquefaction, and gasohol production. In addition, the agency is interested in drinking water pollution control processes involving adsorption mechanisms. In environmental chemistry and physics, the agency is giving particular emphasis to m e a s u r e m e n t methods for volatile and organic aerosols; continuous monitoring devices for criteria and toxic pollutants in air; and the develo p m e n t of novel m e a s u r e m e n t methods for estimating dry deposition of gases and fine particulates. Also of interest is the fate of priority pollutants in the environment and the behavior of toxic metals in n a t u r a l water-sedim e n t systems, with emphasis on their speciation. G r a n t proposals are evaluated by a peer review panel primarily composed of n o n - E P A scientists acknowledged

News as experts in their respective fields. The panels review each proposal and rank it in accordance with its scientific merit. Criteria for review include qual­ ity of research, qualifications of the principal investigator, potential utility of the results, and the availability of suitable facilities and equipment. Interested persons should contact: Grants Administration Division, U.S. EPA, 401 M Street, S.W., Washing­ ton, D.C. 20460 for application proce­ dures and forms.
