Quantitative Evaluation of Contaminants in a Chesapeake Bay Region of Concern: Assimilation Model of Exposure and Bioaccumulation in Baltimore HarborIn Chesapeake Bay, three areas are of special concern with regard to toxic contaminants: the Elizabeth River, the Anacostia River and Baltimore Harbor. This study will focus on Baltimore Harbor where sediments contain high concentrations of many organic contaminants, including DDT, PCBs, chlordanes and PAHs (polyaromatic hydrocarbons). Researchers will develop a simulation model specific to the harbor that will simulate both the carbon and the contaminant flows in the water column and in the sediments. They will use information gathered from all relevant state and national agencies on known organic contaminants in Baltimore Harbor, then screen this information before incorporating it into a database. By developing this contaminant-ecosystem model, the research team will be able to use this single Region of Concern to understand and predict how toxic organic compounds may threaten estuarine systems like the Chesapeake. |
