Temperature is a critical factor due to its effect on both physiology of the organism and the environmental chemistry of the metals. The present study focuses on the toxicity and the bioaccumulation kinetics of Cu and Pb in Notonecta glauca exposed to heavy metal contaminated water system at different temperatures. The result showed that the accumulation of heavy metal gradually increases with increase in temperature and duration of exposure while there was a decrease in LC50 value of Pb and Cu. The calculated uptake factor of lead at different temperatures showed that it has a higher uptake potential than copper.
