In the present study accumulation of cadmium Cd copper Cu iron Fe and zinc Zn in critical organs of yellownecked mice Apodemus flavicollis and bank voles Myodes glareolus trapped in a polluted area in Nováky Slovakia was investigated. Methods Yellow-necked mice n 8 and bank voles n 10 were collected using standard theriological methods for wood ecosystems. All animals were adult males in good physical condition. The concentrations of Cd Cu Fe and Zn in the liver kidney and bone were determined by atomic absorption spectrophotometry. Results The highest concentrations of Cd and Zn were found in the bone of both species while Cu and Fe accumulated mainly in kidney or liver. Significant higher concentrations of Cd and Cu were detected in the liver of bank voles than in yellow-necked mice. Similar significant higher levels of Cd and Zn were found in the bone of bank voles. In contrast significant higher concentrations of Cu and Fe were present in the kidney of yellow-necked mice. Conclusions In the yellow-necked mouse and bank vole bone seems to accumulate Cd and Zn following prolonged exposure. On the contrary kidney and liver store Cu and Fe after a long-term environmental exposure. In the present study bank voles seemed to be more heavy metal loaded zoomonitors than yellow-necked mice. Background The importance of monitoring the exposure and studying the effects of heavy metals on living organisms has increased in the last decades. Studies of small mammals mainly free-living .
