“…In our study in northwestern Poland, there was no significant correlation between Hg concentrations in the various organs and the age and sex of the mallards. This result is similar to those obtained with various Anseriformes from Europe and North America, including the mallard (Florijancic et al 2009; Kalisinska et al 2010; Vermeer et al 1973). …”

The aim of this study was to determine the concentration of mercury (Hg) in liver (L), kidney (K), breast muscle [BM (musculus pectoralis major)], breast feathers (BF), and stomach contents (SC) of mallard (Anas platyrhynchos L. 1758). Among the edible parts of mallard, the greatest concentrations of Hg were observed in K and L, although they did not exceed 1.5 mg/kg dry weight (dw). Average concentrations in K, L, and BM were 0.27, 0.25, and 0.13 mg/kg dw, respectively. Significant correlations were observed between Hg concentrations in BM and K and in BM and L (rs = 0.92) as well as between Hg concentrations in these tissues and BF. In addition, we found significant correlations between Hg concentrations in SC and BM (rs = 0.72) and in L and K (rs = 0.55). In conclusion, mallard exhibits a measurable response to environmental Hg pollution and meets the requirements of a bioindicator.

“…Mercury in crayfish tails (Orconectes virilis) sampled from the stomachs of hooded mergansers (Lophodytes cucullatus) from the Wabigoon-English River system in Ontario, Canada, ranged from 4.7 to 9.6 lg/g (Vermeer et al 1973). Wren and Stokes (1986) sampled crayfish (Cambarus spp.)…”

We collected two species of crayfish, Pacifastacus leniusculus and Procambarus clarkii, from Cache and Putah Creeks, California, and analyzed them for mercury and trace elements. Trace elements were higher in carcasses in 40 cases, higher in tails in 5 cases, and not different in 35 cases; no concentration exceeded levels considered harmful. Mercury concentrations were similar among sites, with no overall sex or species effect in tails. Mercury and methylmercury concentrations were higher in tails at all sites. Methylmercury concentrations in crayfish tails (0.156-0.256 microg/g) exceeded concentrations reported in health advisories for consumption of fish and crayfish from these watersheds.

“…Mercury levels of 0.5-1.5 ug-g" 1 decrease hatchability in Pheasant (Phasianus colchicus) eggs (Fimreite 1971). In contrast, total mercury levels ranging from 2 to 16 ug-g~* had no observable effect in Herring Gulls (Vermeer et al 1973). In the Common Tern {Sterna hirundo) a lower hatching success and reduced fledging rate were associated with mercury concentrations in eggs between 1.0 and 3.6 ug-g" 1 (Connors et al 1975).…”

Feathers of white storkCiconia ciconiachicks in North‐Eastern Greece, as indicators of geographical variation in mercury contamination

Variations in mercury contamination of ecosystems were assessed among areas of northeast Greece by sampling and analysing feathers of White Stork chicks. Mercury concentrations in stork chick feathers were highest in an area known to be affected by riverborne mercury pollution, and were lowest in an inland area away from rivers or lakes. Although regurgitated pellets indicated a predominantly terrestrial diet among White Stork adults, variation in mercury concentrations among localities seemed to relate to pollution of aquatic rather than terrestrial foods of storks. Toxic thresholds of mercury in this species are unknown, but the highest concentrations, observed in chicks from the Axios Delta (up to 4.1 μg.g -1 in feathers) were well above levels having toxic effects in gamebirds. Mercury concentrations in chick feathers increased slightly with chick age and with brood size, but these trends were small by comparison with variations among localities.
