This study is aimed at analyzing the total mercury in the tissues of mammals adapted to a semiaquatic or subterranean lifestyle and at analyzing the possible role of their antioxidant system in heavy metal detoxication. The water shrew Neomis fodiens Pennant, 1771, European mole Talpa europaea Linnaeus, 1758, muskrat Ondatra zibethicus Linnaeus, 1766, and water vole Arvicola terrestris Linnaeus, 1758 were the species under study. Our results indicate that mercury accumulation in the tissue… Expand

Concentration of Mercury in the Livers of Small Terrestrial Rodents from Rural Areas in Poland
The aim of this research was to verify the factors influencing Hg bioaccumulation and to analyze the concentration of total mercury (Hg) in the livers of four species of wild terrestrial rodents from different rural areas of Poland. Expand
Current and historical nephric and hepatic mercury concentrations in terrestrial mammals in Poland and other European countries.
Analysis of abundant data on mammalian hepatic and nephric THg concentrations showed that in 12 of 21 cases, Hg concentrations had dropped significantly since 2000, which signals a reduction in Hg contamination in terrestrial mammals, such as the Eurasian otter, and may be reason for cautious optimism.

Yellow-necked mice (Apodemus flavicollis) and bank voles (Myodes glareolus) as zoomonitors of environmental contamination at a polluted area in Slovakia
Bank voles seemed to be more heavy metal loaded zoomonitors than yellow-necked mice, bone seems to accumulate Cd and Zn following prolonged exposure, and kidney and liver store Cu and Fe after a long-term environmental exposure. Expand
Taiwan's industrial heavy metal pollution threatens terrestrial biota.
Data is presented for the first time on the impact of heavy metal pollution on various terrestrial organisms in Taiwan and a strong influence from industrial pollution on the biotic community is revealed. Expand
Resistance of Eisenia fetida (Oligochaeta) to cadmium after long-term exposure.
It is concluded that worms with a long-term history of exposure to the metal developed resistance to cadmium. Expand
Small mammals as monitors of environmental contaminants.
A relationship between contaminant exposure and trophic level emerged and a substantial number of these biomonitoring studies using small mammals collectively point to the importance of food habits and habitat of small mammals, and their availability and abundance as factors that should influence species selection for monitoring studies.

Hazardous exposure of ground-living small mammals to cadmium and lead in contaminated terrestrial ecosystems
The results indicate a greater risk of toxic exposure to cadmium and lead in soricine shrews than in microtine rodents, and the renal metal loads in shrews reached the critical level, but they remained far below this level in voles. Expand
Comparison between the antioxidant status of terrestrial and diving mammals.
Animals that routinely face high changes in oxygen availability and/or consumption seem to show a general strategy to prevent oxidative damage by having either appropriate high constitutive AD and or the ability to undergo arrested states, where depressed metabolic rates minimize the oxidative challenge.

Effects of Environmental Methylmercury on the Health of Wild Birds, Mammals, and Fish
Abstract Wild piscivorous fish, mammals, and birds may be at risk for elevated dietary methylmercury intake and toxicity. In controlled feeding studies, the consumption of diets that contained Hg (asExpand
Mercury concentrations in deer mouse (Peromyscus maniculatus) tissues from Isle Royale National Park.
Concern is warranted because Isle Royale National park is a protected area in a remote location and any exposure in deer mice represents a path for biomagnification in the terrestrial food web and the source of this mercury remains unidentified. Expand
Total Mercury and Methylmercury Residues in River Otters (Lutra canadensis) from Wisconsin

The Wisconsin Department of Natural Resources collected trapper-caught river otter from 3 distinct areas of Wisconsin and results suggest that Hg accumulates at higher concentrations in fur followed by liver, kidney, muscle, and brain. Expand
Total mercury body burden in Pacific harbor seal, Phoca vitulina richardii, pups from central California.
Because THg concentration and burden in muscle correlated most significantly with other tissue compartments, it is recommended that muscle from the specific sites the authors sampled be used instead of liver or hair for biomonitoring THg in harbor seals. Expand
