Small mammals as biomonitors of metal pollution: a case study in Slovenia
The findings indicate that the majority of small mammals trapped in the area of the former lead smelter are at risk of toxic effects due to the very high bioaccumulation of Pb and Cd in the organism and suggests that Apodemus flavicollis and Myodes glareolus are very suitable biomonitors of metal pollution.
Seasonal effects of lead uptake by snow vole Chionomys nivalis (Martins 1842) in West Tatra Mts.: bone metal concentrations and hematological indices
It is shown that feeding on winter diet (mosses, lichens) could constitute a major pathway for the entry of Pb into food chain of alpine habitats.
Determination of the levels of some heavy metals in African pear ( dacryodes edulis ) marketed in Lagos metropolis, Nigeria
This paper presents the assessment of Pb, Cd and Zn concentrations in the African pear (Dacryodes edulis) sold in eight popular markets in Lagos metropolis, Nigeria. The concentrations of these
Evaluation of chromium accumulation and resulting histopathological changes in Libyan jirds (Mammals, Rodentia), affected by effluent from Ghazghan leather industrial town, Iran
Investigation of the toxic effects of Cr on lung, kidney, liver, and testicular tissues in Libyan jirds inhabiting the area surrounding Ghazghan leather industrial town, Mashhad, Iran found average Cr concentrations were found to be significantly higher in samples from contaminated areas than controls.
Bio-indication of environmental pollution in alpine environments using X-ray analysis in snow vole (Chionomys nivalis) population
In this study we focused on bio-indication of pollution in alpine environments the using snow vole as a bio-indicator species. The research took place in the Dolina Bielych Plies valley, Belianske
Metal pollution from WWTWs affects not only water quality of rivers, but also the diversity of resident aquatic insects and ultimately the ecology of N. nana populations, which may pose serious long-term health risks for these top predators.
Heavy Metal Pollution as a Biodiversity Threat
Heavy metals exert their toxic effects through different mechanisms. Lately, increasing attention has been focused on understanding the long-term ecological effects of chronically exposed populations
Mercury contamination of the snow voles (Chionomys nivalis) in the West Carpathians
The smaller (1-year-old) individuals had higher mercury concentrations in their tails than the bigger individuals, suggesting recent aerial contamination of alpine habitats, and the possible relationship between mercury in the tissues and the seasonal variability of the water cycle in the mountains is discussed.


Effect of soil pollution with metallic lead pellets on lead bioaccumulation and organ/body weight alterations in small mammals

The results suggest that metallic lead pellets deposited in an acidic sandy soil are transformed to a chemical form of lead, probably Pb2+, which is toxic to organisms and which can readily enter the terrestrial food chain.
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.
Food chain analysis of exposures and risks to wildlife at a metals-contaminated wetland
The weight of evidence from the food chain analysis and earlier bioassessment and ecological studies suggest that the health of the wetland receptors is at minimal risk due to the presence of elevated metals in sediments, upland soils, water, or food items at the site.
Uptake of environmental contaminants by small mammals in pickleweed habitats at San Francisco Bay, California
Small mammals were live-trapped in pickleweed (Salicornia virginica) habitats near San Francisco Bay, California in order to measure the uptake of several contaminants and to evaluate the potential

A biological monitoring study should be designed to obtain and make use of the optimum amount of available information by complementing existing environmental studies, or through the simultaneous collection of other environmental data.
A comparison of concentrations of lead in human tissues.

The concentrations of lead in tissues of a mixed group of subjects with no known occupational exposure to lead have been shown to be comparable to the findings in earlier studies, suggesting that children do not possess the same capacity as adults to retain lead in bone.
Lead: Levels in roadside invertebrates and small mammals
Concentrations of lead in the bodies of roadside invertebrates were generally below 50 p.p.m., but reached nearly 700 p.m. in woodlice (Isopoda) and in tissues of small mammals caught on roadside verges, and were thus less than the levels found in many of their prey.
