to investigate the presence of PFAS — or perfluoroalkyl and polyfluoroalkyl substances — in marine environments.

PFAS are human-made chemicals found in food packaging, nonstick cookware, water-resistant clothing, personal care items such as shampoo, and more. They are often called “forever chemicals” because they “usually take hundreds or thousands of years to break down,” the World Economic Forum

Per a University of Portsmouth article on

, scientists collected seawater samples before and after sewage discharges from a U.K. wastewater treatment plant servicing more than 400,000 people. The researchers found PFAS concentrations increased significantly after sewage discharges. Before sewage discharge, one detectable PFAS compound was found in tested waterways. Afterward, eight different PFAS compounds were detected — including two banned PFAS.

The research, recently published in

, also found that seaweed in the studied area contained more than 6,000 times the concentration of PFAS than the water surrounding it. Researchers say this data indicates that seaweed stores the forever chemical in high concentrations — and this stored PFAS could work its way up the food chain when ingested by algae-grazing marine animals.

Why is the presence of PFAS in waterways concerning?

People become exposed to PFAS by consuming contaminated food and water, using products made with PFAS, and breathing in air that contains PFAS. One

Most importantly, the researchers stress the need to develop and implement less polluting replacements for PFAS in products.

“These findings underscore the need for an urgent ban on PFAS from all uses where there are alternatives,” study co-author Francesca Ginley, chemicals policy and advocacy manager at the Marine Conservation Society, said in a
