Contaminated food was prepared by exposing pink shrimp (Penaeus duorarum) to 10 micrograms/1 1,2,4-trichlorobenzene -UL-(14)C (TCB) for 12 days; whole body concentration of TCB in the exposed shrimp was 0.59 micrograms/g. Juvenile spot (Leiostomus xanthurus) were fed the TCB-contaminated shrimp at a daily ration of 10% body weight for 28 days; they accumulated less than 0.05 micrograms/g TCB (detection limits). Spot were exposed to 10 micrograms/l TCB in water for 28 days and fed uncontaminated food bioconcentrated TCB approximately 100 times the aqueous exposure concentration. Spot, exposed simultaneously to contaminated food and water described above, bioaccumulated TCB equal to the aqueous exposure treatment. Results were compared with data from a TCB bioaccumulation with freshwater species; both studies indicated that TCB was accumulated moderately from contaminated water and accumulation from contaminated food was negligible.
