Abstract:The paper reported that the interactive damage of UV B(280~320nm) radiation and polycyclic aromatic hydrocarbons(anthracene) to DNA of Phaeodactylum tricornutum was studied using ecotoxicological and biochemical methods. The results showed that anthracene could inhibit the growth of Phaeodactylum tricornutum, the relative growth rate in Phaeodactylum tricornutum gradually decreased with the increment of anthracene concentration, and the calculated 48h· EC 50 of anthracene to Phaeodact...
