  Abstract
  Aquatic ecosystem is one of the most exposed environments to pollutants. In fact all chemicals whether initially released on land in the atmosphere or directly in rivers will eventually find themselves in the rivers and oceans at the end. Therefore aquatic systems contain a wide range of pollutants from sewage effluents factory wastage agrochemicals pesticides heavy metal etc. Cadmium is considered heavy metal pollutants. Cadmium is a non essential heavy metal. Cadmium act as an endocrine disrupter interfering with biological functions in fish and cause and severe histopathological, biological and physiological changes in various fish species. The present reviews summaries the impact of Cd on gonad (Ovary) with special reference to histological changes and alteration in gonadal hormones.

  Abstract
  The kinetics of the photo-oxidation of dicarboxylic acids by chloramine-T (CAT) in an aqueous medium has been studied. The acids selected for the study are glutaric acid and adipic acid. It is found that reaction obeys first order kinetics with respect to the oxidant (CAT). The reaction shows zero order dependence with respect to substrates. The reaction is found to be catalysed by H+ ions. Different parameters like the effect of the variation of concentration of the reactants, product and intensity of light on the reaction rate have been studied. A suitable mechanism has been proposed depending on the experimental findings.
