This is an award to support preliminary research on the extent to which the pheriphytic biolayer of stream sediments mediates the transfer and transformation of polychlorinated biphenyls and to determine rates of their transformation and/or bioaccumulation and/or transformation. The research to be conducted will involve use of laboratory-scale artificial streams to assess interstream variability, to refine the technical protocols for determination of polychlorinated biphenyls in the sediment and periphytic layers, and to obtain preliminary data on the function of these layers in the transfer process. The proposal leading to this award was submitted in response to the Program Announcement NSF 90-121, Research Planning Grants and Career Advancement Awards for Women Scientists and Engineers. Results of this planning phase are expected to be utilized in developing a full research proposal for consideration of further support by the National Science Foundation.

该奖项旨在支持关于水系沉积物的水生生物层在多大程度上调节多氯联苯的转移和转化的初步研究，并确定它们的转化和/或生物积累和/或转化的速率。将进行的研究将涉及使用实验室规模的人工河流来评估河流间的变异性，完善测定沉积物和周围层中多氯联苯的技术方案，并获得关于这些层在转移过程中的作用的初步数据。导致这一奖项的提案是对NSF 90-121计划公告的回应，该计划是针对女性科学家和工程师的研究规划补助金和职业发展奖。这一规划阶段的结果预计将被用于制定一项全面的研究提案，以供国家科学基金会考虑进一步支持。
