Abstract:
Cadmium tolerance in terms of cadmium uptake (in mg/L) from the aquatic
environment, was studied in golden kuhol (Pomacea canaliculata). Snails of different
ages (one-month and three-months old) were exposed to varying concentrations of
cadmium (0.1875 ppm, 0.375 ppm, 0.75 ppm, 1.125 ppm, 1.5 ppm, 2.0 ppm). Water
samples were taken from each concentration and analyzed through atomic absorption
spectroscopy. Results showed that cadmium uptake was greater with three-month old
snails, and 0.1875 ppm concentration demonstrated maximum cadmium uptake. There
was no significant evidence to show interaction between the age of the snail and
cadmium concentration in aqueous solution to cadmium uptake of snails.
