文摘
Pelagic bacteria represent the potentially mostpredominant biological, particulate sorptive surfacefor hydrophobic organic contaminant (HOC) andconstitute a food source for the microheterotrophicfood web, which conceivably continues up to pelagicfish. However, no data have been reported on HOCsin bacteria. Therefore, this fraction (0.2-2 µm)wasisolated with a new technique in situ in the BalticSeafollowed by HOC analysis (HRGC-MS). Results showbacterial concentrations (PAHs and PCBs) in thesame order as or higher than the larger particulatefraction (2-90 µm), which clearly illustrates thesignificance of heterotrophes for the distribution anddynamics of HOCs in marine waters.
