Additionally, these substances have been used in food packaging due to their ability to make materials grease-resistant and waterproof.
Brief explanation of Per- and Polyfluoroalkyl Substances (PFAS)
PFAS are a class of synthetic chemicals that contain fluorine atoms bonded to long carbon chains. They have been used for over 70 years in various industries due to their unique properties, which include high thermal stability, chemical resistance, and water repellency. However, these same properties make PFAS very persistent in the environment and in the human body, leading to potential health and environmental hazards.
Importance of PFAS regulations
Due to their potential health and environmental hazards, it is essential that we regulate the use and disposal of PFAS. Exposure to high levels of PFAS can lead to a range of negative health effects, including developmental problems in children, liver damage, and increased risk of certain types of cancer. In addition, PFAS can contaminate water sources and accumulate in the food chain, posing a threat to both humans and wildlife. Therefore, it is crucial that we implement regulations to minimize our exposure to these substances and ensure their safe disposal.
Current Regulations
United States Environmental Protection Agency (EPA)
- PFAS Action Plan
a. Lifetime Health Advisory for PFOA and PFOS
The EPA has established a lifetime health advisory for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), two types of per- and polyfluoroalkyl substances (PFAS), at 70 parts per trillion (ppt) each. This advisory is non-enforceable but provides a guideline for limiting human exposure to these contaminants in drinking water.
b. Testing and monitoring of public water systems
