Toxicity And Bioaccumulation Of Tnt In Marine Fish In Sediment Exposures, Guilherme R. Lotufo, William Blackburn, Sydney J. Marlborough, John W. Fleeger
Toxicity And Bioaccumulation Of Tnt In Marine Fish In Sediment Exposures, Guilherme R. Lotufo, William Blackburn, Sydney J. Marlborough, John W. Fleeger
US Army Research
The bioaccumulation potential and toxicity of 2, 4, 6-trinitrotoluene (TNT) spiked to sediment was evaluated in juvenile sheeps head minnows (JSHM, Cyprinodon variegatus) and adult freckled blennies (FB, Hypsoblennius ionthas). The JSHM were exposed for 4 days in the presence or absence of a mesh separating fish from sediment. FB were exposed to sediment for 7 days. During the 24-day storage period(4 °C), extensive transformation of spiked TNT occurred and concentrations are expressed as the sum of TNT, aminodinitrotoluenes and diaminonitrotoluenes (Sum TNT), on a dry weight basis. Sum TNT in the overlying water, not exchanged during exposure, …
