Toxicity Assessment of Textile Dye Wastewater Using Swiss Albino Rats

Haematological and serum biochemical studies on Swiss albino rats were carried out for a period of 15 days to investigate the effects of untreated (Infl uent) and treated (Effl uent) textile dye wastewaters collected from an Effl uent Treatment Plant in Sanganer, Jaipur, India. In comparison to control animals (potable water), values of RBC, WBC, Hb, PCV and MCHC decreased signifi cantly in wastewater exposed animals (12-46%). Also RBC size decreased (13-27%) and the shape modifi ed (poikilocytosis). In contrast, WBC size increased (8-23%). The serum biochemical parameters viz. AST, ALT, urea, creatinine and bilirubin increased signifi cantly (5-97%), whereas an opposite trend was noted for cholesterol, glucose, total protein, albumin and globulin contents (8-53%). The alteration in values was more pronounced in the infl uent-treated animals. When wastewater-exposed animals were kept under control conditions (supplied with potable water) for a period of 45days, the effl uent group recovered faster, attaining values of various investigated parameters similar to the controls. The present study has thus established the toxicity of both untreated and treated textile dye wastewater to the haemopoietic system of male albino rats.
