Abstract

ABSTRACT The surfactant perfluorooctanesulfonic acid (PFOS) is used in various products, but its impact on aquatic organisms like cyanobacteria is poorly understood. PFOS was tested for acute toxicity on the cyanobacterium Microcystis aeruginosa in terms of growth, photosynthetic pigment content, antioxidant response and microcystin production. When exposed to PFOS, the cyanobacterium was sensitive to it, showing significant inhibition of growth and reduction of pigment content. At the same time, exposure to PFOS resulted in a two-fold increase of the content of total carbohydrates and soluble proteins in the cells of M. aeruginosa. There was a significant increase in MDA and H2O2 levels in cells exposed to PFOS, but not in a concentration-dependent manner. Microcystin content tended to increase in PFOS-exposed cyanobacterial cells, although this change was not statistically significant (p > 0.05). These findings suggest that when surfactants like PFOS are used in large quantities or concentrations, they could adversely affect Microcystis populations in the aquatic environment.

接触表面活性剂全氟辛烷磺酸(PFOS)的铜绿微囊藻的生长、抗氧化反应和微囊藻毒素的产生

表面活性剂全氟辛烷磺酸(PFOS)用于各种产品中，但其对蓝藻等水生生物的影响尚不清楚。研究了全氟辛烷磺酸对铜绿微囊藻生长、光合色素含量、抗氧化反应和微囊藻毒素产生的急性毒性。当暴露于全氟辛烷磺酸时，蓝藻对其敏感，表现出明显的生长抑制和色素含量降低。与此同时，暴露于全氟辛烷磺酸导致铜绿假单胞菌细胞中总碳水化合物和可溶性蛋白质含量增加两倍。暴露于全氟辛烷磺酸的细胞中MDA和H2O2水平显著升高，但不呈浓度依赖性。暴露于全氟辛烷磺酸的蓝藻细胞中微囊藻毒素含量有增加的趋势，但这种变化无统计学意义(p < 0.05)。这些发现表明，当大量或高浓度使用全氟辛烷磺酸等表面活性剂时，它们可能对水生环境中的微囊藻种群产生不利影响。
