Peroxidases are involved in redox reactions [l-2] and in particular the redox reaction of haem-containing horseradish peroxidase has been exploited in a diagnostic procedure such as serum cholmterol determination 131. The current chemical techniques for the determination of serum cholesterol is subjected to various interference 14-61, The use of biological catalysts such as horseradish peroxida...

background: the development of toxicity tests regarding toxic responses of different fish species could be more effectively used in predictive toxicology and risk assessment. in this study lethal concentrations (lc50-96 h) values of copper sulphate an important toxic industrial pollutant, on capoeta fusca were determined. behavioral changes at different concentrations of cuso4 were determined f...
