Effect of laying sequence on egg mercury in captive zebra finches: An interpretation considering individual variation
Bird eggs are widely used as noninvasive bioindicators for environmental mercury availability. However, previous studies have found varying relationships between laying sequence and egg mercury concentrations. Some studies have reported that the mercury concentration is higher in first‐laid eggs or declines across the laying sequence, whereas in other studies mercury concentration was not ...

Mercury concentrations in Pacific lamprey (Entosphenus tridentatus) and sediments in the Columbia River basin
The authors investigated mercury accumulation in Pacific lamprey and sediments in the Columbia River basin. Mercury concentrations in larval lamprey differed significantly among sample locations (P < 0.001) and were correlated with concentrations in sediments (r2 = 0.83), whereas adult concentrations were highly variable (range 0.1–9.5 µg/g) and unrelated to holding time after collection. The ...

ZERO MERCURY - Key issues and policy recommendations for the EU Strategy on Mercury (December 2005)
Mercury is a highly toxic metal, causing damage to the nervous system even at relatively low levels of exposure. It is particularly harmful to the development of unborn children. It collects in human and animal bodies and can be concentrated through the food chain, especially in certain types of fish. The Commission’s Directorate General for Health and Consumer Protection has recommended that ...

Mercury Levels in Mink (Mustela vison) and River Otter (Lontra canadensis) from Northeastern North America
Aquatic ecosystems have received mercury released from anthropogenic sources. The northeast region of North America is at especially high risk because of local and regional emission sources, prevailing wind patterns, and certain hydrological and biogeochemical features. Here we examine regional variation in total mercury (Hg) in brain, liver, and fur from otter and mink collected across New York, ...

Unique pattern of molt leads to low intra‐individual variation in feather mercury concentrations in penguins
We hypothesized that the catastrophic annual molt of penguins (Sphenisciformes) would lead to reduced intra‐individual variation of mercury concentrations in body feathers. While mean mercury concentrations varied significantly among 8 penguin species, intra‐individual variability did not differ among species and was three times lower than values observed in other seabirds. Our findings ...

Gasmet CMM offers reliable and sensitive technology for continuous mercury monitoring
Mercury monitoring requires high standards of quality from a measuring technology. In the future, large industrial plants that are producing mercury emissions must ensure that they are able to keep up with the tightened mercury monitoring requirements. At a legislative level,? EU has only fairly recently set limits for the emissions to air of mercury for large combustion plants, among other ...

Bioaccumulation of heavy metals in some fauna and flora
Bioaccumulation of heavy metals in fauna and flora in the Ijaw area of the Niger Delta of Nigeria were investigated. The fauna-molluscs and crustacea, and flora Hibiscus esculentus and vernonia amygdalina were selected for this study. Results show that Molluscs and crustacea accumulate considerable amounts of heavy metals. Higher levels of all the metals determined Hg, Pb, Cr, Cu, Ni, and Zn were ...
