Descrição

Polychlorinatedbiphenyls(PCBs)arelipophiliccontaminantsthattendtoaccumulateinorganisms.PCBs weredetectedin Chelon labrosus, Liza aurata and Liza ramada, alongdifferentagegroups. L. ramada presentedthehighestconcentration,anditincreasedwithage,whereas C. labrosus and L. aurata concentration remainedconstant.
