“…Similar amounts of it was measured in Hungary by Szabó (1998); 0.48 mg/kg in swan's feather, 0.52 ± 0.58 mg/kg in greylag gooses' feather (Anser anser) and 0.18 mg/kg in Mallards' feather (Anas platyrhynchos). Higher cadmium contamination was detected in Pakistan; 2.1 ± 1.28 mg/kg in Accipitridae, 3.22±0.38 mg/kg in Falconidae and 1.11±0.36 mg/kg in Strigidae (Nighat et al 2013). Also, significant concentrations (150±88.2 mg/kg) were measured in herons which live in wetlands (Jungsoo and Tae-Hoe 2007).…”

Concentrations of heavy metals (especially arsenic, cadmium, chromium, copper, mercury and lead) were measured in the contour (body) feathers of mute swans (Cygnus olor) and in its nutrients (fragile stonewort [Chara globularis], clasping leaf pondweed [Potamogeton perfoliatus], Eurasian watermilfoil [Myriophyllum spicatum], fennel pondweed [Potamogeton pectinatus]) to investigate the accumulation of metals during the food chain. The samples (17 feathers, 8 plants) were collected at Keszthely Bay of Lake Balaton, Hungary. Dry ashing procedure was used for preparing of sample and the heavy metal concentrations were analysed by inductively coupled plasma optical emission spectroscopy (ICP-OES). Copper (10.24 ± 2.25 mg/kg) and lead (1.11 ± 1.23 mg/kg) were detected the highest level in feathers, generally, the other metals were mostly under the detection limit (0.5 mg/kg). However, the concentrations of the arsenic (3.17 ± 1.87 mg/kg), cadmium (2.41 ± 0.66 mg/kg) and lead (2.42 ± 0.89 mg/kg) in the plants were low but the chromium (198.27 ± 102.21 mg/kg) was detected in high concentration.

“…Nighat et al (2013) measured similar amount of it in Accipitridae (17.64±4.05 mg/kg), in Falconidae (32.17± 13.66 mg/kg) and in Strigidae species (7.78±2.48 mg/kg).…”

“…As concentration in four species of Strigidae family was 1.06-6.44 mg/kg, and in the USA the concentration of 5 mg/kg was measured in a possible As contaminated area (Nighat et al, 2013;Wiemeyer et al, 1980). The average of Cd concentrations was from 0.09±0.03 to 0.20±0.18 mg/ doi: 10.34116/NTI.2019.AA.21 kg, which is much lower than the accepted threshold value for Cadmium in birds (3 mg/ kg according to Nighat et al, 2013). However, adverse effects can be realised due to level of 0.1-2 mg/kg, in other aspect (Burger, 1993).…”

“…Data for the Zn threshold value in feathers are nonexistent (Clair et al, 2015). The mean Zn values for different raptor species have been reported as 119.14 μg/g for the family Accipitridae (Nighat et al, 2013), 60.01 μg/g for Buteo buteo (Naccari et al, 2009), and 140 μg/g (Kavun, 2004) and 121.84 μg/g (Yamac et al, 2019) for Aegypius monachus.…”

Due to anthropogenic activity, most vulture species are threatened. Neophron percnopterus, the Egyptian vulture, is a vulture species with a declining population. One of the most important factors threatening the species is exposure to chemicals. The second largest population of this bird species is found in Turkey. Accumulation of heavy metals for this species has not been investigated. The aim of this study was to detect and measure As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn values in the feathers of Neophron percnopterus. Calamis and vane, which are different part of the feathers, were analyzed separately with ICP-OES. According to the results, the mean value of heavy metal accumulation is below the threshold levels, except for Pb (mean ± SD = 32.26 ± 74.71 μg/g d.w.) and Cr (mean ± SD = 17.82 ± 33.74 μg/g d.w.) in vanes. On the other hand, all heavy metal values other than Hg and Zn had critical levels, which may result in lethal and sublethal effects on individuals.
