Abstract

The present work aims to check the automotive traffic impact caused by analyze toxic metal concentration in environmental samples in areas near and far from the road and its correlation with lipoperoxides formation in population of Ctenomys minutus (tuco-tucos). Individuals were captured seasonally in three different traffic impact area. From each individual were collected blood to quantify lipoperoxidation by the biochemical assay TBARs (Tiobarbituric acid reactive). In samples of fur, spraints, soils and food vegetation were analyzed Cd, Ni, Pb and Zn. This study show significant difference of toxic metals in areas near the traffic road. The TBARs assay indicates strong seasonal differences. In summer, when the traffic road increase, the index injury was biggest in all the study areas and even greater near the road.
