摘要：
In this study, we investigated the accumulation of cadmium (Cd), lead (Pb), and aluminum (Al) by the alga Enteromorpha prolifera. The metal ions, Cd2+ (5, 20, 80 μg/L), Pb2+ (5, 20, 80 μg/L), and Al3+ (5, 20, 80 μg/L), were added to different culture ponds. Inductively coupled plasma mass spectrometry was used to determine the content of Cd, Pb, and Al in Enteromorpha prolifera. The changes in mineral content were fitted nonlinearly and their kinetic parameters were obtained. The results showed that the accumulation of Cd, Pb, and Al in Enteromorpha prolifera positively correlated with exposure concentration. Accumulation of Cd and Pb satisfied the two-compartment kinetic model, while Al fitted the logistic kinetic model. The two-compartment regression accumulation rate constants (Ka) for Cd were 418.68, 234.30, and 105.57, while the bioaccumulation factors (BCFs) were 1785.12, 1429.67, and 625.69. For Pb, Ka values were 1257.30, 768.81, and 863.83, while the BCFs were 11028.95, 50249.08, and 9119.79. Logistic model regression accumulation rate constants for Al were 0.39, 0.42, and 0.46. Enteromorpha prolifera had relatively strong accumulation effect to Cd, Pb, and Al, which can be significantly predicted for Cd and Pb by the two-compartment model and for Al, by the logistic model. ©, 2014, South China University of Technology.
