Frequently Asked Questions
If your film is about PFASs, why does the title focus only on GenX?
We chose the GenX compound to address the misconception that we only have to be concerned about a single chemical. While many folks have already heard of GenX, it is simply one of many PFASs which exist.
What are PFASs?
PFAS stands for Per & Poly-Fluorinated Alkyl Substance (PFAS). Since the 1950s, PFASs have been used to protect the surfaces of cloth and leather, as coating in food packaging and paper products, and fire fighting foam. C8, the PFAS that came before GenX, was used in the production of Teflon cookware. Ever worn a rain jacket, cooked in a nonstick pan, or gotten French Fries from a fast-food joint? Then you've been using PFASs.
If PFASs are so useful to daily life, what's the problem?
PFASs used in manufacturing have been found in drinking water, air, soil, dust, and food. In some cases, they are detected at great lengths from the facilities from which they are released. They can accumulate inside of people for years and are linked to a wide range of health disorders including but not limited to various forms of cancer, thyroid disease, and birth defects.
Where else are PFASs found?
They have been detected in water, food, air, dust and soil on a global scale including but not limited to: the United States, China, Germany, Korea, the Netherlands, Canada, Denmark, Sweden, Australia, Japan, and the United Kingdom
Is there anything I can do to limit my exposure right now?
Testing by Professor Knappe at NCSU advises that under-the-sink reverse osmosis is the best way to filter the water you drink of PFASs. Additionally, avoiding foods packaged in stain/grease-resistant coatings can help reduce food exposure.
Does my Brita filter do anything to help?
Probably not, as Brita appears to use activated carbon and ion-exchange. These were tested by labs at NCSU and the only effective method for an individual seems to be under the sink Reverse Osmosis.
