Introduction
Understanding and Avoiding PFAS Chemicals
- Definition: PFAS (per- or polyfluorochemicals) are a family of chemicals used primarily for water-, grease-, and stain-repellent coatings.
- Common Uses: They are found in a wide variety of consumer goods and industrial applications.
- Health and Environmental Risks: These chemicals are "notoriously persistent," meaning they do not break down easily in the environment or the human body, and are linked to serious health issues.
- EWG Resources:
- Tap Water Database: A tool to check for the presence of PFAS in local water supplies.
- Fast Food Report: A 2017 study highlighting the prevalence of these chemicals in food packaging.
- Primary Goal: The Environmental Working Group (EWG) provides specific guidance to help consumers identify and avoid exposure to these substances.
