Abstract

Abstract: In the last decades, the use of bisphenol A has attracted global attention resulting from its actions as an endocrine disrupting compound. In this regard, various bisphenol analogues have been manufactured as a replacement for this compound in consumer products. As a result of the high production volumes, different bisphenol analogues are entered into the terrestrial and aquatic environment, which consequently leads to their increasing contamination and may pose serious risk to organisms. Nevertheless, only few studies have reported on the toxic effect of bisphenol analogues on phytoplankton. Therefore, in this study, the anticyanobacterial activity of six bisphenol analogues and their mixture were investigated for the first time. Bisphenol AF, bisphenol B and bisphenol C (14 d, EC50 12.88–54.87 mg L −1 ) exhibit more toxic effect to both tested species in comparison to bisphenol A (14 d, EC50 55.27–78.96 mg L −1 ). Moreover, data show that mixture of bisphenol analogues (14 d, EC50 32.32–60.88 mg L −1 ) exhibit toxic effect similar to or even stronger than that of bisphenol A. The toxic effect of bisphenol analogues, singly and in combination on the growth of both cyanobacteria species was arranged in the following order: bisphenol AF > bisphenol C> bisphenol B> bisphenol A> bisphenol E> bisphenol BP and bisphenol B> bisphenol AF > bisphenol C> bisphenol A> bisphenol E> bisphenol BP for Anabaena variabilis and Microcystis aeruginosa, respectively. This research aims to assure a basic understanding of the toxic effects of bisphenol analogues on cyanobacteria and provides a more comprehensive view on environmental risk assessment. Graphical abstract: Image 1 Highlights: The toxicity of bisphenol analogues (individually and in a mixture) on cyanobacteria was studied. BPAF, BPB and BPC were found to be more toxic to Anabaena variabilis and Microcystis aeruginosa than BPA. Mixture of bisphenol analogues exhibit toxic effect similar to or even stronger than that of bisphenol A. Microcystis aeruginosa was more tolerant to bisphenol analogues than Anabaena variabilis.
