Bioaccumulation test of cadmium and magnesium in the liver of Oreochromis niloticus via Scanning electron microscope

Abstract EN

In this present study, the bioaccumulation of heavy metal, cadmium (Cd) and major element magnesium (Mg), in the liver tissues of Oreochromis niloticus, was investigated after exposing the fish over 96 h period to Cd LC50 (0.8 mg/l) and Mg LC50 (3.03 mg/l).

These tissues were investigated by light and scanning electron microscopy.

Scanning electron microscopic X-ray microanalysis of fish liver exposed to Cd or Mg confirmed that these metals were accumulated in liver tissuesز
