The Chemical and Biological Processes Controlling the Bioaccumulation of Organic Chemicals by Phytoplankton

这项工作将评估控制持久性有机污染物(POP)在浮游植物中生物积累的过程。本研究的重点是多氯联苯，这是一种常见的有机污染物。实验室研究将阐明POPs被浮游植物细胞吸收的机制，并将研究结果纳入先前开发的生物积累模型。这些发现将与之前收集的现场数据进行验证。这项建议是应环境地球化学和生物地球化学征集NSF 99-9的要求提交的，并由海洋科学、分子和细胞生物科学部共同资助。

ABSTRACTThis work will assess the processes that control bioaccumulation of persistent organic pollutants (POP's) in phytoplankton. The study will focus on polychlorinated-biphenyls (PCB's) which is a common organic pollutant. Lab studies would clarify the mechanism of uptake for POPs into phytoplankton cells, and incorporate the findings into a previously developed bioaccumulation model. The findings will be validated against previously collected field data.This proposal was submitted in response to the Environmental Geochemistry and Biogeochemistry solicitation NSF 99-9, and is being funded jointly be the Division of Ocean Science, and Molecular and Cellular Biosciences.
