浓度为 0.1-1.0 mg/1 的铁会导致分批培养中生长的藻类的主要类型从相对无害的绿色转变为形成浮渣的蓝绿色，而不会导致藻类总生物量发生显着变化。结果不依赖于锰浓度（0-0.40 mg/1.）或磷浓度（0.07-7.0 mg/1.）。也许最广泛宣传的控制湖泊过度藻类生长的方法是限制必需营养物，例如从污水和洗涤剂中去除磷。然而，并非所有类型的藻类都同样造成富营养化问题。蓝绿藻会形成表面浮渣并产生气味，在典型的藻华浓度为 6-12 mg/1（干重）时是非常不受欢迎的，而相同数量的绿藻则不那么令人反感。因此，了解控制主要藻类类型的化学和物理条件非常重要。众所周知，某些自然因素和人为因素可以增加绿藻与蓝绿藻的比率（G/BG），但不一定会改变藻类总生物量。生活污水分流外排
Iron, in concentrations of 0.1-1.0 mg/1., causes a shift in the dominant type of algae grown in batch cultures from relatively unobjectionable greens to the scum-forming blue-greens, without causing a significant change in the total algal biomass. Results were not dependent on the manganese concentration (0-0.40 mg/1.) or the phospho-rus concentration (0.07-7.0 mg/1.).Perhaps the most widely publicized method of control-ling excessive algalgrowth in a lake is by limiting an es-sential nutrient, such as the removal of phosphorus from sewage effluents and detergents. However, not all types of algae are equally troublesome in eutrophication problems. Blue-green algae, which form surface scums and cause odors, are very undesirable at typical algal bloom concen-trations of 6-12 mg/1.(dry weight) while the same amounts of green algae are not so objectionable. It is therefore important to understand the chemical and physical conditions that control the dominant algal type. It is well known that certain factors, bothnatural and man caused, can increase the green to blue-green algal ratio (G/BG), without necessarily changing the total algal biomass.
