Abstract
In small oysters (Ostrea edulis), transport of naphthalene between tissues is primarily by diffusion and not via the circulatory system. In intact oysters, accumulation in the adductor muscle and body followed accumulation in the gills after a large lag-time. In isolated tissues with no shell to impede water flux over the body and adductor muscle, there was no lag-time. The molecular diffusivity (D) of naphthalene in oyster tissue, estimated by Fick's second law of diffusion is D = 8 x 10 to the 8th power sq cm per s, a value similar to D determined for lateral diffusion of lipophilic compounds in lipid membrane systems.
