摘要

Crabs were exposed to sub-lethal concentration of Copper Sulphate, Zinc Sulphate and Cadmium Sulphate. Before exposure they were starved for 24 hours to eliminate nutritional effect. After 24, 48, 72, 96 hours exposure time period the rate of heart beat was studied. It was found each metal had different effect upon rate of heart beat.
