Abstract
During 24 and 48 hr of exposure, the digestive glands of Lymnaea treated with a lethal concentration of 0.038 mgl(-1) CuSO4 revealed intense activity of acid phosphatase in perilobular margin. On the other hand, same area of the gland showed moderate activity of ATPase during 24 and 48 hr of exposure. However, alkaline phosphatase showed average activity in perialveolar region and perilobular margin during 24 and 48, and 72 hr of exposure respectively The changes in the activity of these enzymes were nonsignificant in alveolar margin and perialveolar region of the gland. It is interesting to note moderate activity of acid phosphatase in perialveolar region during 24 hr of exposure.
