Effects of pH and humus on the bioavailability of 2,2n, 4,4n, 5,5n- hexachlorobiphenyl-14c in lake-water

The effects of treatment of lakewater with lime adn acid on the vailability of 2,2n, 4,4n, 5,5n- hexachlorobiphenyl to aquatic orgnaisms were studied. A closed laboratory system with hexane-filled dialysis bags of two pore sizes was used, in combination with a 14c labelled PCB isomer and liquid scintillation counting
