Assessment of anthracene on hepatic and antioxidant enzyme activities in Labeo rohita (Hamilton, 1822)

Abstract

Polycyclic aromatic hydrocarbons (PAHs) are widespread pollutants across the global aquatic environment and demonstrate a wide variety of toxic effects in freshwater and marine organisms. The present study aim to estimate the risks of PAHs (Anthracene) to aquatic organisms’ enzymatic biomarkers in Labeo rohita were assessed. Those include antioxidant enzymes (SOD, CAT, GSH), liver damaging enzymes (GOT, GPT,) and LDH, ALP in the liver, kidney, gills and muscle. Fish were grouped into six. Each group was exposed to any one of the different concentration (0(control), 0.5, 1.0, 2.0, 3.0 and 4.0mg/L) of anthracene. The exhibited induction of LDH activity suggesting an increase of anaerobic pathway of energy production. Antioxidant enzymes elevations suggest anthracene induced oxidative stress in aquatic organisms. The increased liver damaging enzymes suggest liver dysfunction due to anthracene in liver cells. The overall results suggest anthracene is a potent toxicant to aquatic environment.
