A flow-through system was used to follow naphthalene and naphthalene metabolite accumulation in the seawater and in the tissue of the oyster Ostrea edulis. After 72 h, 82.5% of the naphthalene carbon was recovered from the system. Glucose was added to seawater to stimulate the pathways of glucose me

โฆ Synopsis
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 -s cm 2 s -1 , a value similar to D determined for lateral diffusion oflipoph/lic compounds in lipid membrane systems.
