Dairy effluent induced alterations in the protein, carbohydrate and lipid metabolism of a freshwater teleost fish Oreochromis mossambicus. Polln Res, 21(3) (2002), 293-295 [10 Ref]. Static bioassays reveal that the LC50 96 hour of dairy effluent for a freshwater fish Oreochromis mossambicus was 50% of the effluent. The fish were reared in different sublethal concentrations (10 and 15%) of the effluent for 30 days. Various biochemical constituent in three tissues (gill, liver, muscle) of the fish were estimated. These concentrations were found to decrease depending on the dose of the effluent. 0301-173. Anand M, Gupta GSD, Rana MD, Khanna RN (Indl Toxico Res Cent, PB No. 80, MG Marg, Lucknow 226001). Peripheral neurotoxicity of cadmium and hexachlorocyclohexane (HCH) in rats. J Ecophysio Occupl Hlth, 2(3&4) (2002), 281-290 [18 Ref]. Male albino rats were divided into five groups and were orally administered cadmium (0.4 mg/kg) and HCH (10 mg/kg) daily for 90 days. After 45 days one group of Cd and HCH was supplemented vitamin E (50 mg/kg) till the end of experiment. The group dosed with HCH + Cd had a significantly higher concentration of HCH in plasma and tissues than the group dosed with HCH alone. The brain content of Cd was significantly increased whereas a marked depletion of copper and iron was observed in the group of Cd + HCH. Vitamin E affords protection against the Cd + HCH induced neuronal toxicity. 0301-174. Asthana A, Pillai A, Gupta VK* (*Sch Std Chem, Pt Ravishankar Shukla Univ, Raipur, Chattisgarh). Spectrophotometric determination of endosulfan. Cheml Environ Res, 11(1&2)(2002), 39-45 [24 Ref]. A sensitive spectrophotometric method is proposed for the determination of widely used pesticide endosulfan. The method is based on the liberation of sulphur dioxide from endosulfan by adding acid reagent and alcoholic potassium hydroxide. The liberated sulphur dioxide is then passed through potassium iodate solution and the iodine liberated is then reacted with N-chlorosuccinimide and leuco crystal violet. The method has been applied for the determination of endosulfan in water, soil and vegetables. 0301-175.

Fenvalerate is used extensively and is most effective pyrethroid. The technical isomer is a mixture of four optical isomers 2 S, a S, 2R and a S. The 2S isomers are more toxic than 2R. The toxic action of the toxicant depends on metabolism and mode of action in aquatic organism. Hence to study it static and continuous flow through tests were conducted to determine LC50 values to the freshwater fish. The possible mechanism of toxic action is presented. 0301-222.
