The aquatic environment has numerous physical and chemical parameters that may influence the physiology and chemical toxicity to freshwater organisms. Temperature is one of the these factors having a marked influence on heavy metal toxicity to fishes and macroinvertebrates. There is a limited and scattered information available on temperature induced changes in acute toxicity of zinc compounds to freshwater pond snails. This information is essential because there are large temperature differences with season and latitudes and the aquatic organisms are subjected to seasonal temperature changes of 20-25/sup 0/C or even more. It is proposed to study the effect of seasonal changes in temperature on zinc toxicity to a freshwater pond snail, Lymnaea luteola (Lamarck), which form an important link in aquatic food chain(s) and are widely distributed in lakes, ponds and rivers of India.
