摘要：The oyster was bred for a week in natural sea water containing 0.1 (control), 20 and 60 ppb Cd (CdCl₂). After the breeding, Cd content in each tissue of the oyster meat was determined by atomic absorption spectroscopy. When the exposure to 60 ppb Cd for a week, the rate of accumulation of Cd in the gill raised up to 56 times the control. Each tissue was homogenized in 0.5 M NaCl solution and an aliquot of the NaCl-soluble fraction was chromatographed on Sephadex G-50. Almost Cd was eluted at the column volume. This suggests that the chemical form of Cd in the oyster meat was characteristic of the low molecular weight materials.
