Four weeks of 'safe' low-level PFAS exposure in tap water altered embryo development in mice

An Adelaide University study has revealed that per- and polyfluoroalkyl substances (PFAS) found in tap water, at levels currently considered safe, affected the development of embryos, causing irreversible damage that may be passed on to future generations. The researchers examined the effects of tap water on female mice following daily consumption for four weeks or six months. The results, published in Environmental Research, showed exposure to PFAS chemicals, even in trace amounts, disrupts female fertility, causing cellular damage to ovulated eggs and embryos.
