Description 324-328
 Laboratory studies
were made to determine the toxicity of cadmium in an intertidal gastropod, Turbo
intercostalis in relation to temperature, salinity and size. The snails
were exposed to various concentrations of cadmium at two different temperatures
and salinities. The tolerance experiments were also conducted with medium and
small sized snails. Mortality rates increased with increasing cadmium
concentration at all the different parameters studied. At ambient
temperature(29°C) and salinity (32%), the LC50 of 6.1844 ppm
was obtained for 96 hr when the medium-size snails were exposed to different
concentrations. The LC50 values of 0.3629 and 0.0577 ppm obtained at
low (25°C) and high (33 °C) temperatures respectively were found to be
significantly (P < 0.05) lower than that of ambient temperature. Similarly,
low LC50 values of 1.154 and 0.3722 ppm were observed at low (20%o)
and high (35%o) salinities respectively. The small size animals
showed LC50 value of 2.774 ppm, which is significantly lower (P
