碩士 / 國立臺灣海洋大學 / 環境生物與漁業科學學系 / 106 / Lead is a highly toxic metal which widespread use and has caused extensive environmental pollution and health problems, especially in aquatic ecosystem. This Study is on the Pb2+ accumulation level, chlorophyll a and phycobiliprotein content of Sarcodia suieae exposed to 1 and 5 mg/L Pb2+ concentration with time elapsed 0, 1, 2, 5 and 10 days.
Pb2+ level varied following the ambient Pb2+ concentrations and exposed time (p<0.05). Moreover, at the end of the experiment the lead content of the seaweed after soaking the acidic solution is reduced compared with the lead content of the algae which has not been soaked with the acidic solution.
Under the 5 mg/L lead concentration environment, the contents of chlorophyll a, phycoerythrin and phycocyanin decreased with the increase of lead concentration in the seaweed, and there was a statistically significant relationship (p<0.05).
At 1 mg/L lead concentration, phycoerythrin and phycocyanin were significantly reduced after 10 days compared with the control. (p<0.05). Allophycocyanin does not change significantly with the increase of Pb2+ level in seaweed (p>0.05).
