| incidence of organochlorine pesticides and the health condition of nestling ospreys (pandion haliaetus) at laguna san ignacio, a pristine area of baja california sur, mexico. | we identified and quantified organochlorine (oc) pesticide residues in the plasma of 28 osprey (pandion haliaetus) nestlings from a dense population in laguna san ignacio, a pristine area of baja california sur, mexico, during the 2001 breeding season. sixteen oc pesticides were identified and quantified. α-, β-, δ- and γ-hexachlorocyclohexane, heptaclor, heptachlor epoxide, endosulfan i and ii, endosulfan-sulfate, p,p'-dde, p,p'-ddd, aldrin, dieldrin, endrin, endrin aldehyde, and endrin ketone ... | 2010 | 20949316 |
| mercury residues and productivity in osprey and grebes from a mine-dominated ecosystem. | mercury (hg) and reproduction and status of western and clark's grebes (aechmophorus sp.) and osprey (pandion haliaetus) were studied from 1992 through 2001 and then less intensely through 2006 at clear lake, california, usa. remediation to reduce hg loading from the sulphur bank mercury mine was initiated in 1992. mercury in grebe feathers declined monotonically from approximately 23 mg/kg dry mass (dm) in 1967-1969 to 1 mg/kg in 2003, but then increased to 7 mg/kg in 2004-2006. mercury in ospr ... | 2008 | 19475927 |
