Abstract

Polycyclic Aromatic Hydrocarbons (PAHs) have become ubiquitous pollutants of water resulting mainly from petroleum products. These are absorbed into the living systems and converted into secondary metabolites which show bioaccumulation in the living systems and have several deleterious effects on them. The present study attempts to evaluate toxicity of two such PAHs— Naphthalene and Anthracene—on the freshwater fish, Rasbora daniconius, using pure PAHs dissolved in dichloromethane. LC50 values were seen in the range of 3.6–4.4 in case of Naphthalene and 0.5–2.4 in case of Anthracene after exposure of fish to these PAHs for 24–96 h. Studies indicated that Anthracene is comparatively more toxic to fish Rasbora than Naphthalene. This paper discusses in detail the toxicity of few PAHs on freshwater fish R. daniconius and the morphological changes observed.
