Can BPA Analogs Affect Cellular and Biochemical Responses in the Microalga Phaeodactylum tricornutum Bohlin?
AI summary Read the abstract
Researchers tested three bisphenol A analogs (BPAF, BPF, BPS) and their mixture on the marine diatom Phaeodactylum tricornutum at environmentally relevant concentrations of 300 ng/L, measuring growth, cell size, and oxidative stress biomarkers. All three analogs and their mixture affected the microalga, raising concerns about the ecological risks of BPA substitutes in marine environments.
Bisphenol A analogs (BPA analogs) are emerging contaminants with a rising production caused by the replacement of BPA with these compounds. The increased production of BPA analogs is leading to their increased release into various ecosystems, including marine ones. The aim of this study was to evaluate the biological effects of BPA analogs on a primary producer, the diatom Phaeodactylum tricornutum Bohlin. Three different BPA analogs (BPAF, BPF, and BPS) and their mixture were tested at the environmental relevant concentration of 300 ng/L. Growth, cell size and several biomarkers of oxidative stress and oxidative damage were measured. Our results indicated that the tested compounds caused a reduced growth rate and induced oxidative stress, altering many antioxidant enzymes in P. tricornutum. However, no oxidative damages were observed.

Can BPA Analogs Affect Cellular and Biochemical Responses in the Microalga Phaeodactylum tricornutum Bohlin?
AI summary Read the abstract
This study tested three bisphenol A replacement chemicals (BPAF, BPF, and BPS) on a marine diatom at environmentally relevant concentrations, finding that all three disrupted algal growth and triggered oxidative stress. Although no actual cell damage was detected at these doses, the results suggest that BPA substitutes are not chemically inert and may still threaten marine primary producers. This is relevant to microplastics research because these bisphenol chemicals leach from plastics and are released alongside microplastic particles in the environment.
Single and multispecies microalgae toxicological tests assessing the impact of several BPA analogues used by industry
AI summary Read the abstract
Researchers tested five BPA chemical analogues (intended as safer BPA replacements) on three marine microalgae species, finding that several analogues — particularly BPFL and BPAF — were more toxic than BPA itself and that results from single-species tests did not reliably predict community-level outcomes, raising concerns about the safety of current BPA substitutes.
Ultrastructural changes, pigment responses and bioaccumulation in the microalga Phaeodactylum tricornutum Bohlin exposed to BPA analogues
AI summary Read the abstract
Researchers exposed the marine diatom Phaeodactylum tricornutum to multiple bisphenol A analogues and found dose-dependent ultrastructural damage, elevated reactive oxygen species, disrupted photosynthetic pigments, and intracellular bioaccumulation, indicating that BPA substitutes pose significant ecotoxicological risks to aquatic primary producers.
Ecotoxicological effects and bioaccumulation of BPA analogues and their mixture in the clam Ruditapes philippinarum
AI summary Read the abstract
Researchers exposed clams to three common bisphenol A substitutes (BPAF, BPF, and BPS) at environmentally relevant concentrations to evaluate whether these replacement chemicals are truly safer. The study found that all three BPA analogues caused oxidative stress, cellular damage, and neurotoxic effects in clam tissues, suggesting that these widely used substitutes may pose similar ecological risks as the compound they were designed to replace.
