Toxic Effect of Lead Pollution on Porphyra Yezoensis

This paper deals with the effect of different cincentation of Pb~(2+) on chlorophylla content,POD, SOD activity, total antioxicatability, soluble protein contents and MDA centent in Porphyra yezoensis.The results showed that with the increase of Pb~(2+)treatment concetration the chlorophylla content,POD, SOD activity, total antioxicatability,soluble protein contents and MDA content appeared a tendency to first increased and then decreased. Porphyra yezoensis is much endurable to Pb~(2+).
