摘要

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 conducting a natural resource damage assessment (NRDA) to assess and restore those natural resources injured by PCBs. As a means of evaluating regional avian contamination, a screening level survey of Eastern screech owl (Otus asio) eggs was conducted in April 2003. This Data Report provides the results of that preliminary investigation conducted pursuant to the NRDA. This collection supplements the avian egg data from the Trustees' Hudson River avian egg exposure preliminary investigation that was conducted from April 2002 through June 2002. In that investigation, 168 eggs from 11 avian species were collected and analyzed. However, only one Eastern screech owl egg was collected and analyzed. In that egg total PCBs (fresh weight basis, as sum of homologues) measured 8,010 ppb.
