RIVM has derived temporary background values for two types of PFAS in Dutch soil: PFOS (perfluorooctane sulfonate) and PFOA (perfluoro octanoic acid).

Research by RIVM shows that the participants in the so-called tROM project, their supervisors and other people involved may have been exposed to chromium-6.

RIVM proposes water quality standards for perfluoro octanoic acid (PFOA). PFOA is a man-made chemical that is used to protect surfaces.
