The invisible, omnipresent “Forever Chemicals” has been linked to a wide range of serious impacts on human health, banning them with increasing calls. Although the fact that at least one of the more than 4,000 man-made chemicals called PFA causes cancer, researchers are still trying to fully understand their comprehensive health effects. Here we know till now.
What are PFAS?
Per- and polypraloralocill substances (PFA) are synthetic chemicals that have been developed to retrieve acute heat and water and grease in the first 1940s. They have since been used in a huge range of domestic and industrial products including food packaging, makeup, stain-proof clothes, nonstick cookware and flame retardments.
Because the PFA takes a long time to break – they earn their nicknames “forever” – they are in soil and groundwater, and from there the food chain and drinking water. These chemicals have been detected everywhere on Earth, from the top of Mount Everest to human blood and inside the brain.
Two biggest criminals
The two most researched PFAS compounds have already been banned or restricted in many countries, although they are detected throughout the environment. Perfluorooctanoic Acid (PFOA), which was once used to make nonstick cooking coating teflon, was classified as “Carcinogenic to Human” by the International Agency for Research on Cancer (IARC) in December.
The World Health Organization Agency said that “enough evidence” was that PFOA gave animals cancer during experiments, as well as “limited evidence” of kidney cell and testes cancer in humans. Perfluorooctanesulfonic Acid (PFOS), once the major component in the scotchguard brand of the fabric protector, was ruled by “possibly carcinogenic for humans”. IARC said there was a limited proof of cancer in animals but “insufficient evidence about cancer in humans”.
Other linked diseases
More broadly, observable studies have suggested that cancer, obesity, thyroid, liver and kidney disease, high cholesterol, low birth weight, infertility and even vaccines in contact with PFAS chemicals Is associated with increased rates. But such observation research cannot prove that chemicals directly cause these health problems, the health authorities say.
There are thousands of PFAs, which makes them difficult to study or determine the effects of any given substance with certainty. The risk can also vary greatly depending on the level of risk – almost all people on Earth have at least slightly PFA in their body. According to the IARC, there are risk people at risk for severe PFAS exposure who work with them directly in manufacturing, such as food, cloth or electronic industries.
Exposure question
In fact, at what level the PFAS exposure is dangerous has been the subject of debate. Earlier, guidelines in many countries ruled that less than 100 nanogram PFA per liter of tap water was safe. But the United States has proposed to reduce the boundary of four nanograms of PFOA and PFO – and the European Union is considering the following suit.
The 2023 media investigation found the level of PFAS over 100 nanograms per liter at 2,100 sites in Europe and Britain. According to the investigation conducted by 16 news rooms, the level of over 10,000 nanograms increased on 300 sites. Last year, a major study found the “dangerous” level of PFAS chemicals in Europe’s rivers, lakes and groundwater, while the other detected the substance associated with “Forever Chemicals” in the European Union’s bottled and tap water.
‘Chemical White-e-Mol’
Further complication of PFA’s ability to understand health effects is that new compounds are still being developed. Potentially dangerous compounds are sometimes replaced by members with low-study members of the PFAS family, warning by researchers. An environmental researcher at Harvard University, Elsei Sunderland has called the process “chemical whee-a-mole”.
Call for action
Environmentalists and health experts around the world have given a rapid voice to the alarm. On Thursday, French MP Nicolas Theory will introduce a bill, which will ban non-essential PFA in France from 2025. The European Union has also been considering the Europe-wide ban on PFA from the beginning of 2026.
What can you do?
It is almost impossible to avoid consuming small amounts of PFA. But experts recommend reducing contact with fast food rapper such as nonstick cookware and grease-proof food packaging. Drinking filtered or bottled water and remaining storage in glass containers instead of plastic can also help.
