ABSTRACT |
The bioconcentration potential and effects of fluoranthene, one of the polycyclic aromatic hydrocarbons (PAHs), on the growth of Porphyra conchocelis were examined. The fluoranthene concentration in conchocelis was 3 to 5 times as much as the concentration of the culture medium when exposed at 0.01-1 ppm. At 10 ppm fluoranthene, however, the tissue concentration did not exceed the one of the medium. Usually the highest concentration was reached at week 2-3. The growth of conchocelis, estimated by tissue weight or chlorophyll a and carotenoids contents, was not influenced by 0.01-0.1 ppm fluoranthene exposed. With higher concentrations of fluoranthene, 1-10 ppm, chlorophyll a and carotenoids contents were markedly reduced after 4-5 weeks of exposure.
