Abstract

Concentrations of total mercury and total cadmium in P. alba were determined by atomic absorption spectroscopy. The results were greatly affected by the type of tissue analysed, the locality where the scallops were collected and, to a lesser extent, by the length of the scallops. Mean concentration of mercury was 0.02 µg g-1wet weight (range 0.01-0.04 µg g-1wet weight) in adductor muscle, 0.02 µg g-1(0.01-0.03 µg g-1) in gonads, and 0.04 µg g-1(0.01-0.11 µg g-1) in viscera. Mean concentration of cadium was 1.0 µg g-1(0.3-1.9 µg g-1) in adductor muscle, 0.9 µg g-1(0.5-1.4 µg g-1) in gonads, and 7.7 µg g-1(3.7-1 5.1 µg g-1) in viscera. The concentrations of mercury tended to decrease in sample..
