Bisphenol Analogs in Aquatic Environments and Their Effects on Marine Species—A Review
AI summary Read the abstract
This review summarized concentrations of bisphenol A analogs found across aquatic environments globally and assessed their toxic effects on marine species, finding that many BPA substitutes show similar endocrine-disrupting, oxidative, and genotoxic activity to the compound they replaced. The findings raise concerns that current BPA alternatives may not represent a meaningful safety improvement for aquatic ecosystems.
Bisphenol A analogs are currently used in manufacturing and as plasticizers as a substitute for bisphenol A. This replacement is taking place because bisphenol A is recognized as an endocrine disruptor chemical (EDC) that can also cause oxidative stress and genotoxic effects in aquatic species. Bisphenol A analogs have a similar chemical structure to BPA, raising doubts about their use as safer substitutes. This review intends to summarize the concentrations of BPA analogs found in aquatic environments and the effects of these emerging compounds on marine species. Generally, studies indicate that BPA analogs have similar effects to their precursor, altering the neuroendocrine system in several marine species. Furthermore, BPA analogs can cause oxidative stress and developmental alterations. The available information on the biological effects of BPA analogs suggests that more effort should be performed to assess the effects of these compounds in marine organisms.

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.

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.
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.
