Four populationsof Rhinella arenarum from aquatic environments with different degrees ofdisturbance in central Argentina were compared to assess the ability ofcytomorphology and cytomorphometry of blood cells as a hematological biomarker.A total of 93 specimens of R. arenarum (adults sexually mature) werecaptured during the spring. From the analysis of cell, no variations were foundin terms of morphology, whereas, nuclear and cell areas and Price-Jones curves,we observed a smaller size in erythrocytes of individuals inhabiting the sitemost altered, Villa Dalcar. As well as for leukocytes: lymphocytes, neutrophilsand eosinophils for the same site. This could be caused by presence ofdifferent pollutants in the lake. Furthermore, this was confirmed by the highlevels of environmental variables (conductivity, total dissolved solids andsalinity) show that Villa Dalcar is the site most affected by human activities
