Sediment from Chesapeake Bay was fortified with naphthalene‐d 8 , diphenyl‐d 10 ether, di‐ n ‐octyl phthalate‐2,3,4,5‐d 4 , p,p ‐DDT‐d 8 and chrysene‐d 12 to measure the bioaccumulation of sediment‐sorbed chemicals by baltic clams ( Macoma balthica ) and soft‐shell clams ( Mya arenaria ). Macoma bioaccumulated the deuterated chemicals from sediment at measurable rates. Uptake transfer coefficients were derived from bioaccumulation, and for Macoma they ranged from 4.95 × 10 −2 h −1 for diphenyl‐d 10 ether to 1.47 × 10 −3 h −1 for chrysene‐d 12 . Transfer coefficients for Macoma were inversely related to the water solubilities of the sorbed chemicals. Mya did not show bioaccumulation of the sediment‐sorbed chemicals. Bedded sediments contaminated with trace organic chemicals may be a relevant source of exposure to toxicants in estuarine habitats for depositfeeding bivalves.
