Abstract

This study demonstrated that although TBBPA had no effects on the growth rate of the R. subcapitata at environmentally relevant concentrations, it induced the production of chlorophyll-a and cell multiplication, which can unbalance food webs. Further studies should investigate the effects of TBPPA on the photosynthesis-related and defense genes against toxicity of microalgae, as well as the potential biomagnification of this emerging pollutant on food webs.
