American Marconi Wireless News - Post-it maker 3M faces Belgian trial over 'forever' chemicals

The residents are demanding almost 30 million euros ($35 million) in total in potential damages in the latest in a series of legal cases worldwide centring on the harm caused by per- and polyfluoroalkyl substances (PFAS).

Abnormal levels of groundwater and soil pollution were detected near a 3M site in Zwijndrecht, outside the port city of Antwerp, in 2021.

A blood-sampling campaign later confirmed that hundreds of people living nearby had been exposed to very high concentrations of perfluorooctane sulfonic acid (PFOS), a member of the PFAS family used as a waterproofing agent.

3M said it has not produced PFAS at the plant inaugurated in the 1970s since 2024 and has launched a soil remediation operation in the area.

But Geert Lenssens, a lawyer for the plaintiffs, said about 1,400 locals are seeking 20,000 euros each in compensation in anticipation of future needs, accusing the US group of "excessive neighbourhood disturbances".

"An illness can take several decades to develop, as we saw with asbestos," Lenssens said, adding his clients' properties in the area also stood to lose value.

- Human-made chemicals -

Heard by an Antwerp judge, the case is scheduled to last three days and follows the successful lawsuit brought by another local family against 3M before the same court, according to Lenssens.

A verdict is not expected before a month.

Often called "forever chemicals" as they take an extremely long time to break down, PFAS are human-made chemicals that repel heat, water and oil, and are used in nonstick pans, stain-proof carpets, and other products.

They are increasingly being restricted across the world due to adverse health effects.

Chronic exposure to even low levels has been linked to liver damage, high cholesterol, reduced immune responses, low birth weights and several kinds of cancer.

3M told AFP it is currently carrying out a large-scale clean-up operation in Zwijndrecht, following a 2022 agreement with local authorities, under which the firm committed to spending half a billion euros on remediation measures.

The company, which has also been sued in the United States over its use of PFAS, said it would end all PFAS manufacturing by the end of 2025.
