The susceptibility of the dinoflagellate Lingulodinium polyedrum to Arochlor 1254, a commercial mixture of polychlorinated biphenyl (PCB) congeners was examined through toxicity bioassays based on cell survival and measures of oxidative balance and adaptive response to PCB stress. The highest Arochlor 1254 concentration that did not cause observed effects (NOEC) on cell growth was 100 (48 h) and 25 ppb (96 h). The concentration that caused maximum effect (MEC) was 300 ppb (48 h) and 250 ppb… CONTINUE READING
