Effects of PAH Mixtures on Haematological, Hepatic and Oxidative Stress Biomarkers in Clarias gariepinus

Haematological, hepatic and oxidative stress parameters in juvenile Clarias gariepinus exposed to a combined ternary mixture of naphthalene, phenanthrene benzo[a]pyrene were investigated under static-renewal bioassay conditions. The test organisms two levels treatments the mixed compounds for period 35 days. Red blood cell (RBC) count, haemoglobin (Hb) concentration haematocrit (Hct) significantly lowered fish compared control. Significant decreases also observed mean corpuscular volume (MCV), (MCH) (MCHC). White (WBC) platelet (PLT) counts raised There significant reductions total plasma protein bilirubin. While increases superoxide dismutase (SOD) catalase (CAT) significant, that glutahthione s-tranferase (GST) was not significant.
