and animal tests conducted by PFAS producing companies in the 1970s concluded that PFOS and perfluorooctanoic acid (PFOA) should be regarded as toxic. In 1998, the United States Environmental Protection Agency (EPA) was first alerted to the risks associated with PFAS and a year later PFOS contam...
Researchers and manufacturers are also working to incorporate shorter-chain PFAS in place of the long-chained chemicals, to see if the chemicals can achieve the same useful properties, according to the ITRC. Short-chain PFAS may be less harmful and are less likely to accumulate in humans and a...
PFAs, or per- and polyfluoroalkyl substances, to give them their full name, are a subset of chemicals which are infamous for their extremely long half-lives. This has led to them being dubbed “forever chemicals”, since many of them can persist in the natural environment for centuries or ...
Some PFAS compounds known to be toxic have been registered as substances covered by the Stockholm Convention on Persistent Organic Pollutants and are now prohibited or restricted from being manufactured or used. In April 2024, the US Environmental Protection Agency (EPA) published Final Maximum Cont...
New testing indicates major fast-food chains are still serving up PFAS (per- and polyfluoroalkyl substances) with some of their most popular takeout foods, despite increasing consumer demand and legislative action to phase out the use of toxic PFAS chemicals. ...

eliminators, you and your toddler won’t inhale potentially harmful synthetic scents; if you skip dry cleaning, the person who works at the cleaners may be exposed to fewer cancerous solvents; if you opt out of waterproof-ing your boots, your whole community may have fewer PFAS in the ...
Added chemicals can include highly toxic compounds like carcinogens, endocrine disrupters, and neurotoxicants, or chemicals with reproductive effects, such as BPAs, phthalates, bisphenols, and per- and polyfluoroalkyl substances (PFAS). A series of studies has begun bearing out the human toll of ...
According to theAgency for Toxic Substances and Disease Registry, there are a number of health impacts of PFAS exposure, including: Reduce fertility in women Increase cholesterol levels Increase the risk of certain cancers Affect the immune system ...
impacts of toilet paper occur all along its supply chain. Making TP is an energy- and water-intensive process, and also requires toxic PFAS and other chemicals. Upon disposal, toilet paper can become an insoluble pollutant that resists wastewater treatment and adds bulk and chemicals to sewage ...
