Figure 2

Histopathological observations in the kidney of Diplodus cervinus after 28 days of exposure to Hg²⁺. (a) control group: posterior kidney section (bar = 50 𝜇m); (b) exposure to Hg²⁺: posterior kidney section showing a massive necrosis area (nec) and cytolysis (cy) (bar = 200 𝜇m). (c) exposure to Hg²⁺: occlusion of the tubular lumen (otl) (bar = 50 𝜇m).
