Teflon is made of Polytetrafluoroethylene (PTFE)
Granite cookware is marketed as a non-toxic and easy-to-cook-and-clean option. However, it is prone to chipping and scratching, which affects its durability. Additionally, granite cookware may not distribute heat evenly, leading to unevenly cooked meals.
Teflon, on the other hand, is made of Polytetrafluoroethylene (PTFE), a chemical compound that forms a coating to prevent sticking. While Teflon offers non-stick properties and is suitable for low-fat cooking and delicate foods, it has some significant drawbacks. Firstly, it can release toxic fumes when heated to high temperatures, posing health risks to users. Secondly, Teflon-coated products are prone to chipping, and these chips can adhere to food and be ingested, leading to potential health issues.
It is worth noting that both PTFE and PFOA (perfluorooctanoic acid), a chemical previously used in the production of Teflon, are considered dangerous materials for cooking. While PFOA has been discontinued in the US and EU markets, PTFE is still present in some cookware. To ensure safety, it is recommended to choose cookware that is entirely PTFE and PFOA-free, such as vitreous enamel or porcelain-coated options, which are safer alternatives to Teflon-coated pans.

PTFE breaks down into toxic PFAS chemicals
Granite cookware is marketed as a non-toxic, easy-to-cook, and easy-to-clean option. However, it is important to note that granite pans may sometimes be coated with Teflon, which contains PTFE, a chemical that breaks down into toxic PFAS chemicals.
PTFE, or polytetrafluoroethylene, is a chemical substance known for its excellent heat resistance, electrical insulation properties, and water repellency. It is commonly used as a non-stick coating for pans and other cookware due to its non-reactive nature. However, despite being marketed as a safe alternative to other PFAS chemicals, PTFE itself is a member of the PFAS family.
PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals that have earned the nickname "forever chemicals" because they do not break down and remain in the environment indefinitely. This persistence allows PFAS to accumulate in animal tissue and the environment, causing continuous harm to human health and the ecosystem. PFAS are found in various products, including non-stick cookware, textiles, and even drinking water.
The production of PTFE contributes to the presence of PFAS in the environment. In the process of creating PTFE, PFAS are used, leading to emissions and wastewater discharge containing these toxic chemicals. This has been observed in areas surrounding manufacturing plants, where high concentrations of PFAS have been detected.
The health effects of PFAS exposure are concerning. Studies have linked PFAS exposure to various health issues, including cancer, ulcerative colitis, thyroid disease, and high cholesterol. The EPA has also classified GenX, a replacement chemical for PFAS, as more toxic than its predecessor.
To avoid exposure to PFAS and its potential health risks, consumers should opt for cookware that is not only PFOA-free but also PFAS-free and PTFE-free. While granite cookware may be marketed as a safe alternative, it is important to research the specific brand and its manufacturing processes to ensure it does not contain PTFE or other toxic chemicals.

PFAS chemicals are harmful to humans and the environment
Per- and polyfluoroalkyl substances (PFAS) are a large and complex group of synthetic chemicals comprising almost 15,000 variations. They have been used in various everyday products since the 1950s, including non-stick cookware, food packaging, clothing, carpets, and firefighting foam. PFAS molecules are composed of carbon and fluorine atoms, forming one of the strongest chemical bonds, which makes them highly persistent in the environment and resistant to degradation. This persistence leads to the bioaccumulation of PFAS in the bodies of humans and other organisms, posing significant health and environmental risks.
PFAS exposure can occur through multiple routes, including contaminated water, food, soil, dust, air, and consumer products. Surveys by the Centers for Disease Control and Prevention (CDC) indicate widespread PFAS exposure in the United States, with certain populations facing higher exposure levels due to occupational hazards or proximity to PFAS-producing facilities. Pregnant and lactating women, as well as children, may also be at increased risk of exposure due to higher water intake per pound of body weight.
PFAS chemicals, particularly Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS), have been associated with numerous health issues. PFOA, a carcinogen, has been linked to various health risks and is considered a "forever chemical" due to its persistence in the environment. While PFOA has been phased out in the United States and other countries, it has often been replaced by other PFAS chemicals, such as PTFE (polytetrafluoroethylene), which is commonly known as Teflon. However, PTFE has also been found to break down into PFAS, raising concerns about the potential toxicity of cookware coated with these substances.
The environmental impact of PFAS is significant due to their persistence and ability to move through the environment. PFAS can contaminate soil, water, and air, leading to the exposure of various organisms and the disruption of ecosystems. Their presence in water bodies, including public drinking water systems and private wells, poses a particular concern for human health. The complex nature of PFAS, with thousands of variations, also makes them challenging to study and regulate, hindering our full understanding of their health and environmental implications.
To address the risks associated with PFAS, regulatory agencies like the U.S. Environmental Protection Agency (EPA) and other federal agencies are authorized to develop and enforce regulations. These regulations aim to prevent the release of hazardous chemicals, including PFAS, into the environment and to protect human health and ecosystems. Additionally, initiatives such as the PFAS Strategic Roadmap outline commitments and actions to tackle PFAS contamination and find more enduring solutions.
In summary, PFAS chemicals are harmful to both humans and the environment due to their persistence, bioaccumulation potential, and widespread exposure. The health risks associated with PFAS exposure, particularly PFOA, have led to global efforts to phase out these substances. However, the replacement chemicals, such as PTFE or Teflon, may also pose health concerns. Regulatory actions and ongoing research are crucial in mitigating the impact of PFAS and finding safer alternatives for consumer products.
