Hudson River: Congener-Specific Analysis of PCB Residues in Tree Swallows

Date Posted: October 18, 2011

The Hudson River Natural Resource Trustees have released:  "Congener-Specific Analysis of Polychlorinated Biphenyl Residues in Tree Swallow Chicks, Eggs and Other Biota from the Hudson River." Dated August 1, 2011, this data report contains U.S. Geological Survey (USGS) Final Laboratory Report FY-97-30-01 dated November 25, 1996. This report addresses samples from tree swallows (eggs, pre-fledgling chicks and adults), wood ducks (eggs and adults) and mallard ducks (eggs and adults) collected from the Hudson River in 1995 and analyzed by the USGS, Biological Resources Division, Columbia Environmental Research Center in Columbia, Missouri. Insect samples were also collected and analyzed. This work was conducted as part of the Hudson River Natural Resource Damage Assessment (NRDA).

Natural resources of the Hudson River have been contaminated through past and ongoing discharges of polychlorinated biphenyls (PCBs). The Hudson River Natural Resource Trustees -- New York State, the U.S. Department of Commerce, and the U.S. Department of the Interior -- are working cooperatively to conduct this NRDA to assess and restore those natural resources injured by PCBs.
