| Abstract: | To investigate the effects of polycyclic aromatic hydrocarbons (PAHs) and metals on the population reproduction,antioxidative defense system and cell ultrastructure of the marine diatom,fluoranthene and Cu2 were selected to test their toxicity to Phaeodactylum tricorntum,in the laboratory.The results indicated that both fluoranthene and Cu2 inhibited population reproduction of P.tricorntum.When the algal cells were exposed to fluoranthene or Cu2 for 72 h,ultrastructure damage in the cells was observed un... |
