“…The bird species feeding on primary producers such as vegetal nutrients, seeds, leaves, roots, fruits and algae are the group which are influenced the least from environmental pollutants (Zolfaghari et al,2007;Behrooz et al,2009). Parallel to other studies on this subject, the mercury concentration level was also found the lowest in the birds feeding on plants in our study (0.56 mg/kg).…”

Abstract. In this study, mercury (Hg) concentrations were detected in feathers of 22 bird species from 10 different families living in terrestrial and aquatic ecosystems in Van Lake Basin in Turkey. The mercury rates in feathers were detected based on nutrition status and taxonomic classifications of bird species. Mercury levels were detected in 0.002 ± 0.007 mg/kg and 2.700 ± 0.560 mg/kg dry weight range. It was observed that there was a significant difference between the groups classified taxonomically (p < 0.05). The highest concentrations were detected in European Honey-buzzard (Pernis apivorus) 2.7 mg/kg, Lammergeier (Gypaetus barbatus) 0.45 mg/kg and Long-legged Buzzard (Buteo rufinus) 0.28 mg/kg species from Accipitridae family. And the lowest mercury concentration was detected in Golden Eagle (Aquila chrysaetos) from the same family (0.002 ± 0.007 mg/kg). Mercury was detected in the feather samples taken from the Egyptian Vulture, Lammergeier, Northern Lapwing, and Great Bustard, and these species were determined to be within different endangered categories according to the International Union for Conservation Nature (IUCN). Considering the trophic level (type of food) and systematic groups of the sampled species, it was determined that average mercury level was statistically significant in both cases. It was suggested that the mercury level of the carnivorous ones were higher than that of the herbivorous ones.

“…A bigger sample sizes than those available in the present study are needed to conclude the transformation capability in the organisms or on the role of migration habitats in the contamination distribution. For instance, the purple heron migrates to the southwest of Iran (Khouzestan and along with Persian Gulf) and therefore may pick up an important load of pollution from these grounds (Mansoori 2008;Behrooz et al 2009). The role of contaminants picked up on wintering grounds is yet to be determined.…”

Mercury levels were determined in feathers from 83 birds belonging to 18 species (eight families), all collected from the northern region of Iran. Mercury levels were evaluated in relation to taxonomic affiliation and feeding strategies. Mercury levels in the feathers were between 0.05 ± 0.01 and 1.10 ± 0.15 μg g(-1) dry weight, and there was a significant effect of taxonomic groups (p < 0.05). The highest mercury levels were found in Accipitridae, and mercury was not detected in the family Upupidae. The pattern for mercury levels was Accipitridae > Pelecanidae > Sternidae > Ardeidae > Anatidae > Rallidae > Phasianidae (p < 0.05). Significant differences (p < 0.05) in the mean mercury levels were found among species as a function of feeding method and trophic level. Mercury levels were highest in the carnivorous species and lowest in the herbivorous species. Mercury levels in feathers of birds in this study were generally below the thresholds reported to affect reproduction.

“…Levels found in razorbill feathers are much higher than those found in the feathers of both aquatic and terrestrial bird species for RHCH and RDDT (Dauwe et al 2005;Jaspers et al 2006aJaspers et al , 2007aJaspers et al , 2007bJaspers et al , 2008Jaspers et al , 2009Behrooz et al 2009a;Behrooz et al 2009b), except an individual of European scops owl (Otus scops) ( P HCH = 212 ng/g; P DDT = 295 ng/g) and eleven individuals of Sparrowhawks (Accipiter nisus) ( P DDT arithmetic mean = 230 ng/g) which have similar levels (Behrooz et al 2009b;Jaspers et al 2007a). The razorbill diet, consisting mainly of fish (80-90% volume), and their migratory status are factors that increase OC exposure (Johnsgard 1987;Kinusue et al 2002).…”

“…Moreover, this result shows the capacity of feathers as an excretion route for this compound. Behrooz et al (2009aBehrooz et al ( , 2009b studied organic compounds in various bird species from Iran, and also found that lindane was the most predominant HCH isomer in feathers, which they felt was due to recent exposure of birds to c-HCH.…”

Razorbill (Alca torda) feathers as an alternative tool for evaluating exposure to organochlorine pesticides

The aim of this study was to explore the usefulness of feathers as a biomonitoring tool for organochlorine pesticides (OC) in a razorbill population (Alca torda). Fifteen OC were analyzed in feathers, including α-, β- and δ-hexachlorocyclohexane, lindane, aldrin, dieldrin, endrin, endosulfan I and II, endosulfan sulfate, p,p'-DDT, DDD, DDE, heptachlor and its epoxide. The geometric mean concentrations observed in this study were ∑DDT 67.40 ng/g, ∑HCH 62.88 ng/g, ∑Heptachlor 61.75 ng/g, ∑Endosulfan 19.70 ng/g, and ∑Drins 10.17 ng/g. The higher OC levels found in this study compared with other studies are probably affected by the razorbill diet and migration status. However, levels found in the feathers of the present study are related to concentrations in internal tissues below those which cause adverse reproductive and behavioral effects or other signs of organochlorine-pesticide poisoning in birds. Age does affect the concentration of OC pesticides in feathers. Thus, feathers would appear to be a promising tool for OC biomonitoring in seabirds, since it is possible to quantify OC compounds.
