项目摘要
DESCRIPTION (Taken from application)
Large quantities of toxic metals remain dispersed in the environment where
their distribution and fate are imperfectly characterized, especially near
large urban centers where both emissions and population density are
concentrated. Moreover, significant quantities of metals continue to be added
to the environment, particularly to natural waters where they accumulate in
sediments and, in cases such as Hg, can be accumulated by fish and thus reach
human diets. A central aim of this project will be to better characterize
current sources and transport mechanisms of Pb, Hg and other metals to the NY
metropolitan area and Hudson River basin. We will continue to work in very
close collaboration with ongoing research on chlorinated hydrocarbons. Our
approach will be to reconstruct and extend temporal trends in contaminant
levels, including Pb isotope compositions, through analysis of dated
environmental samples (airborne particulate matter from filters, sediments
core depth profiles and landfill ash deposits of known age) to assemble the
history of development and use of municipal and non-municipal waste
incinerators in New York City, and to compare our sediment-derived contaminant
history to NYS DEC's database on contaminant levels in fish from several parts
of the Hudson River basin. We will expand our use of urban lakes and park
soils to characterize the temporal history and geographical extent of urban
atmospheric deposition rates of metals. Data generated should allow us to
investigate potential for human exposure to metals and chlorinated
hydrocarbons from city parks and community gardens, to investigate human
exposure pathways of chlorinated organics and Hg via fish consumption, and
contribute to ongoing state and federal investigations of Superfund sites
within the metropolitan area and Hudson River Basin.
