Assessment Quantifies Extent of Sediment Contamination, Toxicity in Chesapeake Bay

The National Centers for Coastal Ocean Science (NCCOS) has released “Magnitude and Extent of Contaminated Sediment and Toxicity in Chesapeake Bay“, a report that provides chemical contaminant and benthic organism information useful for management planning efforts and understanding the Bay ecosystem. Sediment contaminants often pose ecological and human health risks through degraded habitats, loss of […]
