The objective of the current study was to evaluate biochemical and immunological responses tilapia, Oreochromis niloticus due heavy metals pollution. Histomorphological alterations in liver kidney suggested tissue damages this polluted water exposure. brain acetylcholinesterase (AChE) as an indicator neurotoxicity significantly (P < 0.01) decreased after 10 days exposure fish metal contained river water, while plasma glutamate oxalacetate transaminase pyruvate were increased 0.01). Moreover, superoxide dismutase, catalase, glutathione peroxidase, S-transferase enzyme activities, well reduced malondialdehyde levels treated compared control. Additionally, glucose level blood serum Ca2+ concentrations exposed Hematological indices such Hemoglobin, RBC, WBC, MCV etc. different comparison that control fish. cytokines i.e. IL-1β, IL-6, TNF-α present findings explored detrimental effects on at levels.
