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.

摘要: We identified and quantified organochlorine (OC) pesticide residues in the plasma of 28 osprey (Pandion haliaetus) nestlings from a dense population Laguna San Ignacio, pristine area Baja California Sur, Mexico, during 2001 breeding season. Sixteen OC pesticides were quantified. α-, β-, δ- γ-hexachlorocyclohexane, heptaclor, heptachlor epoxide, endosulfan I II, endosulfan-sulfate, p,p′-DDE, p,p′-DDD, aldrin, dieldrin, endrin, endrin aldehyde, ketone OCs found nestlings, ranging 0.002 to 6.856 pg/μl (parts per billion). No differences concentration between genders (P > 0.05). In our work, concentrations detected lower than those reported be threat for species that affect survival reproduction birds. The presence remote Ignacio is an indication ubiquitous nature these contaminants. are apparently able travel long distances their source study area. A significant relationship hemoglobin mean corpuscular suggesting potential effect on health chicks may exist this caused by OC, e.g. anemia. total proteins positively correlated with α-BHC, I, p,p′-DDD. It has been suggested also affects competitive interactions status over term vertebrate species, results could used as reference information comparison other more exposed populations.
