Japanese seabass (Lateolabrax japonicus) and three related species from western Japan were examined.

All 209 PCB congeners in tissues were analyzed by HRGC/HRMS; we determined 2485515000249&_mathId=si16.gif&_user=111111111&_pii=S2352485515000249&_rdoc=1&_issn=23524855&md5=35000492368fadfa0328da607bf4c43a" title="Click to view the MathML source">δ15N and 2485515000249&_mathId=si17.gif&_user=111111111&_pii=S2352485515000249&_rdoc=1&_issn=23524855&md5=e46ab80d7079d4808f72f439610034cb" title="Click to view the MathML source">δ13C signatures.
