Trace Metals

While the Hudson and New York/New Jersey Harbor complex are best known for incidents of PCB and dioxin contamination, the sediments are also among the nation's most contaminated with trace metals (Table 26.1).

The use of 137Cs analyses to guide interpretation of trace metal data in Hudson sediment samples dates back to the 1970s (Williams etal., 1978). Copper, lead, and zinc levels were interpreted in terms of three-endmember mixing. The "recent harbor" endmember had detectable levels of 137Cs and the highest trace metal levels.
