3M Knew About PFAS Toxicity Since 1970s While Continuing Production
Key points
- 3M knew PFAS were toxic since the 1970s.
- The company kept this information secret for decades.
- PFAS are now found in most people and environments globally.
- These chemicals are linked to developmental, immune, and hormonal effects.
Discovery of Widespread Contamination
"Forever chemicals," also known as PFAS, are now understood to be present in the bodies of most people on Earth. These human-made chemicals were used in products like nonstick pans, food packaging, mascara, firefighting foam, and stain-proof coatings for furniture and clothing. From these products and manufacturing facilities, PFAS have spread extensively into the environment.
3M's Concealed Knowledge
ProPublica reporter Sharon Lerner's investigation revealed that 3M, a company that pioneered the production of PFAS, knew about the toxicity of these chemicals and their presence in public bloodstreams as early as the 1970s. Despite this knowledge, 3M continued to produce and distribute these chemicals for decades, keeping the information secret.
Health and Environmental Impact
PFAS do not break down easily in the environment or in human bodies, earning them the moniker "forever chemicals." They are associated with developmental, immune, thyroid, liver, and hormonal system effects, and some types are linked to cancer and obesity. The widespread and persistent nature of these chemicals has transformed a localized issue into a global environmental and public health concern.

Reporting from
A report reveals that 3M, a pioneer in "forever chemicals" (PFAS) production, was aware of their toxicity and presence in human blood since the 1970s but kept this information secret. This concealment allowed the widespread distribution of these chemicals, which are now found globally in humans and the environment, leading to various health issues.
