A Study on the Accumulation of Copper and Zinc in the Mid-gut Gland Cultured Scallop for Environmental Monitoring

Abstract

Accumulation profile of copper and zinc in the mid-gut gland of cultured scallop was analysed statistically with reference to their ambient level. The levels of both copper and zinc found in the mid-gut gland increased as the organ weight increased, and a linear relationship was observed. The coefficient of the correlation eas characteristic with their ambient level. It was confirmed that the profile analysis of the heavy metals accumulation in the midgut gland is useful for estimating a trend of their level in the environment.And also cultured scallop could be a suitable indicator organism for environmental monitoring, which has been suggested in the previous paper.
