英文摘要: The autochthonous dissolved organic matter (DOM) released by Microcystis aeruginosa (M. aeruginosa-DOM) during its growth period was characterized by spectroscopy. Furthermore, the relationships between the M. aeruginosa-DOM spectroscopic descriptors and the pyrene binding coefficient (KDOC) values were explored. The results showed that the spectroscopic characteristics of the M. aeruginosa-DOM and the binding properties of pyrene were dynamically changed along with the algae growth. Pearson correlation analysis demonstrated that a higher pyrene KDOC value was observed for the M. aeruginosa-DOM that has a higher humification index (HIX) value, a lower biological index (BIX) value and a lower absorption ratio (E2/E3). The presence of protein-like and long-wavelength-excited humic-like components may impose negative and positive effects on binding of pyrene by the M. aeruginosa-DOM, respectively. Principal component analysis (PCA) further supported that the binding affinity of pyrene may be primarily influenced by the humification degree of the M. aeruginosa-DOM. © 2016 Elsevier Ltd.
