Measurements in 2021 and 2022 confirm that sea foam may contain PFAS and that PFAS concentrations may change depending on the place and season or time. It is a guess as to the origin of PFAS in the sea foam. Deposition from the Scheldt is possible, but other currents or causes also lead to the PFAS deposition.
However, the health risks for coastal visitors are limited, according to the Agency for Care and Health. “Swimming, bathing or playing in seawater does not pose any health risks, because the concentrations of PFAS in seawater are much lower than in sea foam. The concentrations can be higher in the sea foam, but that is not always the case and there is also not always sea foam present Sporadic contact with sea foam is not a problem.
But it is recommended not to swallow the sea foam and not to let children play in the sea foam. Good hygiene after a day at the beach is always wise: rinse your body and wash your hands, especially before eating,” says Joris Moonens, spokesperson for Care and Health.
