Cover Story: This study tests the hypothesis that microalgae (Phaeodactylum tricornutum) exposed to BPA analogues, namely, BPAF, BPF and BPS, exert negative effects on primary consumers, such as the clam Ruditapes philippinarum. After exposure to BPA analogues, microalgae were supplied as food to bivalves. The effects of this dietary exposure were evaluated on a battery of biomarkers measured in the haemolymph/haemocytes, gills and digestive glands of the clams. Bioaccumulation in the clams was also evaluated. The results obtained demonstrated that a diet of BPA-analogue-exposed microalgae can induce significant alterations in some important biological responses of R. philippinarum, suggesting a potential ecotoxicological risk for the marine food chain, at least at the first few levels. View this paper
