Due to their high assimilative capacities salt marshes may act as a sink for introduced compounds, retaining substances transported by terrestrial and tidal inflows, and often changing the chemical composition of transported substances through transformations that occur within the estuarine system. Of concern are polynuclear aromatic hydrocarbons (PAHs), halogenated organics and metals which are manufacturing byproducts which can threaten human health.

This study will use catabolic response profiles (CRP) to characterize differences in substrate utilization by microbial communities associated with Spartina alterniflora and Phragmites australis vegetation in contaminated and non-contaminated systems.
