Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The acute and chronic toxic effects of Bisphenol A (BPA) on <italic>Chlorella pyrenoidosa</italic> (<italic>C. pyrenoidosa</italic>) and <italic>Scenedesmus obliquus</italic> (<italic>S. obliquus</italic>) were not well understood. The indoor experiments were carried out to observe and analyze the BPA‐induced changes. Results of the observations showed that in acute tests BPA could significantly inhibit the growth of both algae, whereas chronic exposure hardly displayed similar trend. Superoxide dismutase (SOD) and Catalase (CAT) activities of both algae were promoted in all the treatments. Chlorophyll a synthesis of the two algae exhibited similar inhibitory trend in short‐term treatments, and in chronic tests <italic>C. pyrenoidosa</italic> hardly resulted in visible influence, whereas in contrast, dose‐dependent inhibitory effects of <italic>S. obliquus</italic> could be clearly observed. The experimental results indicated that the growth and Chlorophyll a syntheses of <italic>S.obliquus</italic> were more sensitive in response to BPA than that of <italic>C. pyrenoidosa</italic>, whereas for SOD andCAT activities, <italic>C. pyrenoidosa</italic> was more susceptible. This research provides a basic understanding of BPA toxicity to aquatic organisms. © 2012 Wiley Periodicals, Inc. Environ Toxicol 29: 714–722, 2014.</p> </abstract>
