A database of avian blood spot examinations for exposure of wild birds to environmental toxicants: the DABSE biomonitoring project.

摘要: DABSE, a database for avian blood spot examination exposure to toxicants, is new biomonitoring project in wild birds that has the goal of providing reference values harmful agents, as measured whole stored dried spots. Once these “normal” have been established, diagnosis environmental contaminant-mediated ill-health (such manifestations sickness, increased mortality, reduction population, poor breeding success, abnormal behavior) an individual bird or population could be facilitated by comparing investigation same species database. One might then identify cause and pave way mitigating response. The toxicant component DABSE being examined at low ng ml−1 level 200 µl blood. As analyses are invariably very costly, effort made lower costs so enable more testing quantitating representative compounds markers group. These found birds' highest concentration all constituents groups comprise:- (a) elements—arsenic, cadmium, lead, mercury selenium; (b) organochlorine pesticides, p,p′-DDT, p,p′-DDE, β-HCH, HCB oxychlordane; (c) polychlorinated biphenyls (PCBs), marker congener 153; (d) polybrominated diphenyl esters (PBDEs), 47; (e) perfluorinated (PFCs), perfluorooctane sulfonate (PFOS) perfluorooctanoic acid (PFOA). will expanded determine infectious diseases perhaps acute toxicoses.
