Accumulation and depuration of trinitrotoluene and related extractable and nonextractable (bound) residues in marine fish and mussels

To determine if trinitrotoluene (TNT) forms nonextractable residues in mussels (Mytilus galloprovincialis) and fish (Cyprinodon variegatus) and to measure the relative degree of accumulation as compared to extractable TNT and its major metabolites, organisms were exposed to water fortified with 14C-...

Zusammenfassung:	To determine if trinitrotoluene (TNT) forms nonextractable residues in mussels (Mytilus galloprovincialis) and fish (Cyprinodon variegatus) and to measure the relative degree of accumulation as compared to extractable TNT and its major metabolites, organisms were exposed to water fortified with 14C-TNT. After 24 h, nonextractable residues made up 75% (mussel) and 83% (fish) while TNT accounted for 2% of total radioactivity. Depuration half-lives for extractable TNT, aminodinitrotoluenes (ADNTs) and diaminonitrotoluenes (DANTs) were fast initially (
