摘要

Different sizes of Littorina littorea were collected from four areas in the Firth of Clyde, Scotland. Their metal- lothionein (MT) and heavy metal concentrations were analysed using the Silver Saturation Method and Atomic Absorption Spectrophotometry, respectively. Concentra- Tions of MT, Cd and Zn (as μg g~-1 dry soft-body weight) Generally decreased with an increase in size of L. Littorea. MT concentrations were better correlated with Cd than With Zn or Cu concentrations. Nevertheless, MT and the Metals in periwinkles (as μg individual~-1) increased sig- Nificanlty with increasing size.
