Health perspectives and handling of PFAS contamination in Denmark.

Per- and polyfluorinated alkyl substances (PFAS) are a group of man-made extremely persistent chemicals that have been spread worldwide since the 1950s due to their properties as effective water- and grease-repellent and heat- and temperature-resistant. They are associated with an increasing number of health effects including immune and hormonal disturbances and some types of cancer. We present a review of PFAS pollution in Denmark, the current human exposure, suspected health effects, and patient management in environmental medicine.
