Radiobiological monitoring of striped field mouse populations in the Moscow recreation forest "Kuzminki".

The results of radiometric and haematological studies of striped field mice (Apodemus agrarius) sampled over the years 1995-2003 from the territory of the preserved radioactive waste burial (RWB), which is located in the Moscow recreation forest "Kuzminki", are presented and discussed in the paper. It was shown that the level of 90Sr-90Y content in mice sampled from the RWB area varies within the range of 0-1200 Bq/kg with an average of 98.7+/-21.

DNA-protein cross-links in leukocytes of mice induced by Zn, Cd, and Pb.

A single subdermal injection of CdCl2 or Pb(CH3COO)2 results, together with remarkable changes in the blood cell pattern, in increased DNA-protein cross-links in mouse leukocytes in 24 h; after 15 days the DNA-protein cross-linking returned to the initial level. In contrast, after injection of ZnSO4 a high level of DNA-protein cross-links is retained during the whole observation period (15 days). In the studied range of doses the formation of DNA-protein cross-links is proportional to the logarithm of the dose.
