Abstract: | The time-courses of uptake for 2,4,5,2,5-pentachlorobiphenyl (PCB) by 11 marine phytoplankton species were measured and found to be rapid, with equilibration occurring within 0.5 to 2.0 h. These data were described with the empirical Freundlich adsorption isotherm. The relationship between cell density and accumulation of PCBs was also investigated. Concentration factors on a volume per volume basis ranged from 1.23x104 to 2.41x106 for the 11 algal species examined. These values are comparable in magnitude to factors reported previously for phytoplankton in natural marine systems. |
