New study: PFAS is transferred from mother to fetus

Already in the mother's womb, fetuses get PFAS. The substances pass through the placenta throughout the pregnancy and accumulate in the fetal tissue. This shows a new study by researchers at the Karolinska Institute in Stockholm.

The study was carried out in close collaboration with researchers from Copenhagen University and Rigshospitalet. The research was funded by the EU project ReproUnion, the Novo Nordisk Foundation, the Research Council Formas and the Jane and Aatos Erkko Foundation.

- Today, food is the main source of PFAS substances, in the form of fish, milk, meat and eggs, or drinking water if you happen to live in a polluted area. We get them as a cocktail of substances that can also interact with each other. It would be in line with the precautionary principle in the limitation of chemical substances to ensure that all PFAS substances disappear from our society, ”says Pauliina Damdimopoulou.

Highly fluorinated substances in the environment

PFAS is a collective name for approximately 3000 industrially produced chemicals. They are used in a large number of products, are widely distributed in the environment, extremely persistent and some are toxic. In the industry, they are used in surface treatment of food packaging and in the manufacture of fluoropolymers, which are used, inter alia, in frying pans and baking trays.

  • Perfluorinated substances are a group of organic substances characterized by being completely fluorinated, ie. they contain a carbon chain where each hydrogen atom is replaced by a fluorine atom. The chemical bond between carbon and fluorine is one of the strongest available.
  • In fact, the perfluorinated substances are probably not degraded at all in the environment.
  • Polyfluorinated substances are very similar to the perfluorinated substances, but are not as stable and can be degraded. In the environment, they can be broken down and become perfluorinated. They are often used as a substitute for perfluorinated substances.

The Madrid declaration on PFAS

  • Stop using PFAS where they are not essential or when safer alternatives exist.
  • We call on the international community to cooperate in limiting the production and use of PFAS.
  • As scientists and other professionals from a variety of disciplines, we are concerned about the production and release into the environment of an increasing number PFAS.
  • Increasing use of fluorinated alternatives will lead to increasing levels of stable perfluorinated degradation products in the environment, and possibly also in biota and humans.
  • PFAS are found in the indoor and outdoor environments, wildlife, and human tissue and bodily fluids all over the globe.
  • In animal studies, some long-chain PFAS have been found to cause liver toxicity, disruption of the immune system and tumors in multiple organ systems.
  • Although some of the long-chain PFAS are being phased out, the most common replacements are short-chain PFAS with similar structures.

Teflon is considered to cause cancer

Producers must pay around €780,000,000 in damages to victims.

DuPont knew about the health risks posed by C8 (also called PFOA which is a PFAS) in Teflon as early as mid 60’s after performing lab tests on animals (monkeys, dogs, rats) and all of the tests showed bad, bad health effects. By 80’s they were already warning their employees that C8 could cause cancer, but they were not telling the general public. They showed a conscious disregard for the health and safety of people.

People are going to become ill as times goes on. This is a product that is in their blood and stays there for a very long time. There is a dramatically increased risk of thyroid disease, testicular cancer and kidney cancer.

There should be no C8 (PFOA) in the environment or in anybody’s blood.
