“…Heavy metals are ubiquitous, highly persistent, and non-biodegradable with long biological half-lives (Burger et al 2007). Toxic concentrations of heavy metals affect the central nervous system and disrupt the functioning of internal organs (Lee et al 2006).…”

“…''Different species of birds such as herons and egrets have been used as a bio-indicator and/or bio-monitor of local environmental contamination because they are high on the food-chain, exposed to a wide range of chemicals, susceptible to bioaccumulation and are geographically widespread'' (Burger 1994(Burger , 1995Scheifler et al 2006;Burger et al 2007;Deng et al 2007;Horai et al 2007). Various studies have evaluated heavy metal accumulation in different body organs (Elliott and Scheuhammeri 1997;Mateo and Guitart 2003;Deng et al 2007;Horai et al 2007;Kojadinovic et al 2007), blood (Scheifler et al 2006), eggs (Fasola et al 1998;Burger and Gochfeld 2004), eggshells (Ayas 2007), feathers (Fasola et al 1998;Movalli 2000) and prey samples (Zhang et al 2006) of different bird species.…”

“…Variation in heavy metals concentration in different feathers of an individual bird has been related to molting pattern, differences in pigmentation or external contamination. Fledging feather contaminant concentration has been used as a bio-indicator of heavy metal pollution of local environment (Fasola et al 1998;Burger et al 2007). Bird's feathers have a potential in environmental studies to assess ecological health of the local ecosystem, and can be used as a non-destructive bio-monitoring tool.…”

Concentrations of metals such as Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Ni, Pb, and Zn were analyzed in the feathers of cattle egret (Bubulcus ibis) from three breeding colonies in the Punjab province, Pakistan. The mean concentrations of Ca, Cd, Fe, Pb and Mn were significantly different between the three study sites (River Chenab, River Ravi and Rawal Lake Reservoir). The mean concentrations of Ca, Cd, Fe and Mn were significantly greater at the River Chenab heronry and Cr, Co, Zn, and Pb concentrations at the River Ravi heronry. The feathers of cattle egrets collected from the Rawal Lake Reservoir heronry were least contaminated. Multivariate statistical methods viz., Factor Analysis based on Principal Component Analysis (FA/PCA); Hierarchical Cluster analyses (HACA), and Correlation Analyses identified relatively similar associations of metals and their sources of input. Metals such as Ca, Mg, and K were related with natural input from parent rock material whereas trace metals viz., Cu, Cd, Co, Pb, Ni, and Zn were associated mainly with anthropogenic processes. Metals such as Fe, Mn, and Li were either correlated with natural input or with anthropogenic activities. Concentration of heavy metals such as Cd, Pb, and Cr were well above the threshold level that can cause adverse effects in birds and pose menace to the cattle egrets population in Pakistan. The study suggested that the feathers of cattle egret could be used as a bio-monitor of the local heavy metals contamination.

“…Teški metali ulaze u lance ishrane preko prirodnih ili antropogenih izvora (Qadir and Malik, 2009). Teški metali su stalno prisutni nebiorazgradivi elementi sa dugim biološkim poluživotom (Burger et al, 2007). Oni se akumuliraju u različitim tkivima i organima, sa majke se prenose na jaja i mladunce.…”

“…Iako cink (Zn) ima bitnu ulogu kao kofaktor preko 300 enzimskih sistema (ATSDR 2005), kao i ulogu u formiranju pera, povećane koncentracije dovode do sličnih simptoma kao i povećane koncentracije bakra. Mangan (Mn) je deo mnogih enzimskih sistema i pored drugih funkcija povezan je sa formiranjem kostiju (ATSDR 2008), ali u visokim koncentracijama dovodi do redukovanog rasta, smanjenja sinteze hemoglobina, anemije (Burger et al, 2007). Nikl (Ni) je važan u procesu pigmentacije pera kod ptica, a eliminiše se tokom mitarenja (Honda et al, 1986).…”

The Aleutian Archipelago is an isolated arc of over 300 volcanic islands stretching 1,600 km across the interface of the Bering Sea and North Pacific Ocean. Although remote, some Aleutian Islands were heavily impacted by military activities from World War II until recently and were exposed to anthropogenic contaminants, including mercury (Hg). Mercury is also delivered to these islands via global atmospheric transport, prevailing ocean currents, and biotransport by migratory species. Mercury contamination of freshwater ecosystems is poorly understood in this region. Total Hg (THg) concentrations were measured in threespine stickleback fish (Gasterosteus aculeatus) collected from eight lakes at Adak Island, an island in the center of the archipelago with a long military history. Mean THg concentrations for fish whole-body homogenates for all lakes ranged from 0.314 to 0.560 mg/kg dry weight. Stickleback collected from seabird-associated lakes had significantly higher concentrations of THg compared to non-seabird lakes, including all military lakes. The δ13C stable isotope ratios of stickleback collected from seabird lakes suggest an input of marine-derived nutrients and/or marine-derived Hg.
