“…However, it is unlikely that pesticide and herbicide chemical contamination will have the same impact as NSAIDs (Pain et al 2003). The ingestion and bioaccumulation of lead in bone tissues can also be a major problem in long-living birds of prey including vultures (Mateo et al 1999(Mateo et al , 2001Gangoso et al 2009). Recent research on broad spectrum animal husbandry antibiotics by Lemus et al (2009) has found that fluoroquinolone residues were obtained from most unhatched eggs sampled in Central Spain.…”

Abstract:Of the nine Accipitridae vulture species found within Nepal the IUCN categorises White-rumped, Indian Vulture, Slender-billed and Red-headed Vultures as Critically Endangered and Egyptian Vulture as Endangered. Dramatic declines have occurred since the mid 1990s with the White-rumped Vulture, Indian Vulture and Slender-billed Vulture population declining by over 97%. The remaining species are listed as Near Threatened or Least Concern. Veterinary use of the non-steroidal anti-inflammatory drug (NSAID) diclofenac has been proven to be a key threat in the region for Gyps vultures and appears likely that it may also affect other Accipitridae vultures. The drug is transferred to vultures via consumption of dead livestock carcass. Ingestion of the drug causes visceral gout and kidney failure, which leads to the birds' death. Consumption of diclofenac and the majority of other non-steroidal anti-inflammatory drugs are fatal to individuals. Only one NSAID, meloxicam, has been tested and proven safe for vultures. There are other factors such as food shortage in local scale, habitat loss, climate change and pesticides/poisoning that play some role on population decline. Managing vulture conservation across Nepal can be problematic just as it is throughout the Indian subcontinent due to the variable level of protection afforded to vultures through legislation and enforcement in each political region particularly regarding NSAID regulation and use. However, great gains have been made on removing diclofenac from sale within the Indian subcontinent. Continuing and enhancing the holistic conservation approach between all stakeholders, government and non-government organisations, across the species range is required to conserve them for future generations. Indeed, it is likely that a number of species will become extinct if a greater conservation effort is not forthcoming in the very near future.

“…Pb in blood samples diluted 1:10 with 0.1% triton was analyzed using graphite furnace atomic absorption spectroscopy (GF-AAS; AAnalyst800 with autosampler AS800, Perkin-Elmer) following Mateo et al (1999). Calibration standards were prepared from commercial solutions containing 1 g/l of Pb (Panreac) and ultrapure grade water.…”

and in all common pochards (Aythya ferina) (n ¼ 4), but common coots (Fulica atra) (n ¼ 37) and moorhens (Gallinula chloropus) (n ¼ 12) were all o 20 mg/dl. ALAD ratio in mallards and coots decreased with PbB levels 4 6 mg/dl. In mallards, an inhibition of glutathione peroxidase (GPx) and an increased level of oxidized glutathione (oxGSH) in red blood cells (RBC) were associated with PbB levels 4 20 mg/ dl. In coots, PbB levels were negatively related to vitamin A and carotenoid levels in plasma, and total glutathione in RBCs; and positively related with higher superoxide dismutase and GPx activities and % oxGSH in RBCs. Overall, the results indicate that previously assumed background levels of PbB for birds need to be revised.

“…Noninvasive methods like regurgitated pellets or blood samples can be useful for determining heavy metal exposure, its seasonality, and food items with level of heavy metal load (Mateo et al, 1999). However, these methods can still be difficult sometimes for raptors inhibiting mountainous or wooded habitats in the nonbreeding season.…”
