Effect of nitrogen/phosphorus concentration on algal organic

发布时间：2024-02-26 21:56

　　Critical algal blooms in great lakes increase the level of algal organic matters(AOMs),significantly altering the composition of natural organic matters(NOMs) in freshwater of lake.This study examined the AOM’s characteristics of Nitzschia palea(N.palea),one kind of the predominant diatom and an important biomarker of water quality in the great lakes of China,to investigate the effect of AOMs on the variation of NOMs in lakes and the process of algal energy.Excitation–emission matrix fluorescenc...
