A paper has just been released that will raise health concerns about Bisphenol A again. The paper, “Low-dose exposure to bisphenol A and replacement bisphenol S induces precocious hypothalamic neurogenesis in embryonic zebrafish” was published in the Proceedings of the National Academy of Sciences. This is a very interesting paper, but in terms of implications for human health everything hinges on what “low dose” means.
