title: Comparative disposition and biotransformation of naphthalene in fresh- and seawater-acclimated striped bass (Morone saxatilis).
abstract: 1. The disposition and biotransformation of naphthalene in striped bass (Morone saxatilis) acclimated to either fresh- or seawater have been determined. 2. The 24-h total concentration factor did not significantly differ between the freshwater (283.7 +/- 61.5 [+/- SD]) and seawater (245.5 +/- 44.4)-acclimated bass. At both salinities, the viscera/gonad and liver accumulated large concentrations of residues, whereas the skin retained the largest total residue mass. 3. During the 24-h depuration period, the freshwater-acclimated bass depurated 45% of retained residue and the seawater-acclimated bass depurated 85% of retained residue. 4. Naphthalene was primarily excreted unchanged (> 99% in freshwater-acclimated bass and > 88% in seawater-acclimated bass), but small amounts of 1,2-dihydro-1,2-dihydroxynaphthalene and 1- and/or 2-naphthylsulphate were formed.
