“…This has raised toxicological concerns for both wildlife and mankind, based on historical and ongoing trends in the use of organochlorines. The environmental contaminants especially the OCPs are persistent, and on many occasions, they tend to concentrate in wildlife through the food chain (Guitart et al 1994;Henriques et al 1997) and have profound consequences by way of increased reproductive dysfunction (Custer et al 2000), increased susceptibility to diseases or other stresses, and changes in normal behavior patterns (White et al 1986). Due to their lipophilic properties and resistance toward metabolic breakdown, organochlorines are transported through the food chain with strong biomagnifications at the higher trophic levels ( Van den Berg et al 1994).…”

The presence of persistent organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were determined in blood plasma of white-backed vulture Gyps bengalensis, Egyptian vulture Neophron percnopterus, and griffon vulture Gyps fulvus collected from Ahmedabad, India. All the samples had varying levels of organochlorine pesticides and PCBs. Statistically significant (P<0.05) differences among species were detected for beta-hexachlorocyclohexane (β-HCH), ∑HCH, and dichloro-diphenyl-trichloroethane (DDT). The mean concentration of ∑HCH, ∑DDT, and ∑PCBs among plasma ranged from 43.7 to 136, 8.8 to 64.8, and 226 to 585 ng/ml, respectively. Among the various OCPs analyzed, 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (p,p'-DDE) was detected most frequently. The concentrations of cyclodiene insecticides detected were lower than the other organochlorine residues. The levels of pesticides measured in plasma samples of three species of vulture were comparable to the results documented for a number of avian species and were lower than those reported to have deleterious effects on survival or reproduction of birds. Although no threat is posed by any of the organochlorine pesticides detected, continuous monitoring of breeding colonies is recommended. This study is also the first account of a comprehensive analysis of toxicants present in blood plasma of vulture species in India. The values reported in this study can serve as guidelines for future research in general as well as control values during the analysis of samples obtained from birds in the event of suspected organochlorine poisoning.

Organochlorine pesticide residues were determined in tissues of five Indian white-backed vultures and two of their eggs collected from different locations in India. All the samples had varying levels of residues. p,p'-DDE ranged between 0.002 microg/g in muscle of vulture from Mudumali and 7.30 microg/g in liver of vulture from Delhi. Relatively higher levels of p,p'-DDT and its metabolites were documented in the bird from Delhi than other places. Dieldrin was 0.003 and 0.015 microg/g while p,p'-DDE was 2.46 and 3.26 microg/g in egg one and two respectively. Dieldrin appeared to be lower than the threshold level of 0.5 microg/g. p,p'-DDE exceeded the levels reported to have created toxic effects in eggs of other wild birds. Although varying levels of DDT, HCH, dieldrin, heptachlor epoxide and endosulfan residues were detected in the vulture tissues, they do not appear to be responsible for the present status of population in India.

“…Equally, cadmium concentration in eggs of Black headed orioles in this present research work is at variance with the research work of [21] who also reported a higher cadmium concentration of 0.82±0.25mg/kg and 5.21±0.17mg/kg in yolk and shell of Black headed gull in Poland. Lower values of cadmium concentration of 0.694mg/kg and 0.915mg/kg were also reported in ju venile and adult birds respectively [22] in Lesser Scaups wintering in Indi ana Harbour canals in USA and also the work of [23] who reported cadmium concentration of 1.274mg/kg and 0.469mg/kg in liver and breast muscles of mallards and pheasants respectively from Slask in Poland. Metal accumulation in birds is a function of environmental pollution, so that a careful managed environment with strict adhesion to environmental laws will produce low metal concentration.…”

An investigation to determine cadmium concentration in Black-headed oriole Oriolus brachyrhynchus was carried out using Atomic Absorption Spectrometry (AAS). The organs are feather, liver heart, skin, nestling feather, egg and the carcass. A total of 30 birds were caught using mist net and 150 of these organs were obtained, whereas 9 eggs and 9 nestling were collected from different nest in the study locations. The concentration measured in mg/kg in the organs from the various locations Buruku, Daudu and Adega were compared using descriptive statistics. Cadmium concentration in the feather has the highest mean value of 4.26±0.59mg/kg in Daudu in the liver; 4.58±0.49mg/kg in Buruku, heart; 3.65±1.13mg/kg in Buruku and in skin; 0.41±0.35mg/kg in Buruku whereas carcass has 6.68±0.63mg/kg in Buruku. Equally, cadmium concentration in egg; 0.10±0.01mg/kg was highest in Daudu and nestling feather; 4.19±0.33mg/kg in Buruku. A very significant correlation (r 2 = 0.778) existed between feathers and carcass (P˂0.01), r 2 = 0.662 between weight of feather and heart (P˂0.05). Furthermore, a negative correlation (r 2 = -0.702) existed between weight of skin and heart (P˂0.05), and (r 2 = -0.723) between liver and skin (P˂0.05). Cadmium concentration in maize was highest 3.72±0.49mg/kg in Daudu and in rice; 1.53±0.04 mg/kg in Buruku while 3.76±1.46mg/kg in Daudu. In soil and water cadmium concentration was highest 6.04±0.19mg/kg and 0.07±0.1mg/l in Buruku respectively. The reason for high cadmium concentrations in the species from this study is due to agricultural activities such as application of fertilizer, production of bricks, bush burning and emission from exhaust of vehicles. However this call for concern since the permissible limit for wild birds has been exceeded.
