| changes in contaminant levels in new jersey osprey eggs and prey, 1989 to 1998. | ospreys are good indicators of the health of estuarine areas because they feed almost exclusively on fish with the balance on other aquatic biota. through the 1980s, ospreys nesting on delaware bay in new jersey had reduced reproductive success relative to those nesting on the atlantic coast and the maurice river, a tributary of delaware bay. earlier research suggested that elevated levels of ddt and polychlorinated biphenyl (pcb) contaminants identified in addled osprey eggs contributed to this ... | 2001 | 11243331 |
| effects of contaminant exposure on reproductive success of ospreys (pandion haliaetus) nesting in delaware river and bay, usa. | despite serious water-quality problems and pollutant loading and retention, delaware river and bay (usa) provide important wildlife habitat. in 2002, we conducted a comprehensive evaluation of contaminant exposure and reproduction of ospreys (pandion haliaetus) breeding in delaware river and bay. sample eggs were collected from 39 nests and analyzed for organochlorine pesticides, polychlorinated biphenyls (pcbs), and mercury; a subset of 15 eggs was analyzed for perfluorinated compounds and poly ... | 2005 | 15779762 |
| concentrations of metals in blood and feathers of nestling ospreys (pandion haliaetus) in chesapeake and delaware bays. | in 2000, 2001, and 2002, blood and feather samples were collected from 40-45-day-old nestling ospreys (pandion haliaetus) from chesapeake bay and delaware bay and river. concentrations of 18 metals, metalloids, and other elements were determined in these samples by inductively coupled plasma-mass spectroscopy, and hg concentrations were measured by cold vapor atomic absorption spectroscopy. when compared to concurrent reference areas (south, west, and rhode rivers), mean as and hg concentrations ... | 2008 | 17763889 |
