We evaluated the effect of cadmium (Cd) on the structure and function of the head
kidney in the freshwater fish Colossoma macropomum (C. macropomum). Juveniles
were exposed to 0.1 mg/L CdCl2 for 31 days. Blood samples were examined using
hematological tests and head kidney histology was determined by light microscopy.
The concentration of Cd in the head and trunk kidneys was measured using an
atomic absorption spectrophotometer. Cd produced histopathological changes in the
head kidney, the most evident of these being: the thickening of the vein wall, an
increase in the number of basophils/mast cells close to blood vessels and a
severe depletion of hematopoietic precursors especially the granulopoietic
series. In the blood, a decrease in the total leucocytes and hemoglobin
concentration was observed. Cd-exposed fish showed higher Cd concentrations in
the trunk kidney than the head kidney. In conclusion, exposure to Cd affected
precursor hematopoietic cells in C. macropomum.
