Toxic Effects of Tributyltin and Triphenyhin on Antioxidative Defense System in the Sea Urchin <i>Strongylocentyotus intermedius</i>

The aim of this study was to investigate the harmful effects of TBT and TPT using sea urchin Strongylocentyotus intermedius . At 2, 4, 6, 8, 10 days after TBT and TPT exposure, the examinations were taken. The results revealed that administration of TBT and TPT reduced the activities of antioxidants CAT and GPx, while MDA content increased. It was suggested that TBT and TPT were toxin with a variety of deleterious effects on sea urchin, indicating that oxidative injury and antioxidant defense system damage were induced by TBT and TPT.
