From Military Origins to Environmental Invasion

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are not a recent invention. Their history dates back to the 1930s when DuPont developed the first PFAS, perfluorooctanesulfonate (PFOS), for use in firefighting foams.

1930-1950: Quiet Beginnings

The initial development of PFAS occurred during a time of war and rapid technological innovation. Their unique properties, such as water and chemical resistance, made them particularly attractive for military and industrial applications.

  • 1940: PFOS used for the first time in firefighting foams for military aircraft.
  • 1945-1950: Development and use of PFAS in other military applications like lubricants and protective coatings.
  • 1950: Introduction of PFAS into civilian industries, especially in waterproof textiles and food packaging.
PFAS were initially developed for military applications, leveraging their lubricating properties

1950-1980: Expansion and Diversification

Post-war growth saw an exponential increase in PFAS usage across a variety of industrial and domestic applications.

  • 1960: PFBS introduced to the market.
  • 1967: PFOS first used in Teflon manufacturing, a revolutionary non-stick coating.
  • 1970s-1980s: Increasing use of PFAS in consumer products like waterproof clothing, carpets, furniture, and cookware.

The commercial success of PFAS was built on their performance and versatility. Their widespread adoption across various industries led to their pervasive presence in our environment and daily lives.

1980-2000: Initial Warnings and Research Development

During this period, scientists began questioning the environmental and health impacts of PFAS. Studies revealed these substances’ persistence in the environment and their ability to accumulate in living organisms.

  • 1999: Discovery of PFOS contamination in the blood of animals and humans.
  • 2000: Initiation of scientific studies to evaluate the potential health risks of PFAS.

A Turning Point in PFAS History

The 2000s marked a significant shift in PFAS history. Awareness of the potential dangers of these substances led to gradual regulation and efforts to remove them from the environment.

Conclusion

The history of PFAS from 1930 to 2000 is one of innovation and commercial success, but also of unawareness of potential dangers. The discovery of PFAS contamination and subsequent scientific studies triggered awareness and a series of measures to protect human health and the environment.
