Pfas: Persistent Pollutants And Their Impact On Our Health

Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals that have been widely used since the 1940s in a range of products, from industrial applications to consumer goods, due to their unique properties such as oil and water repellency, temperature resistance, and friction reduction. PFAS have gained notoriety as forever chemicals due to their persistence in the environment and their ability to accumulate in living organisms, including humans. PFAS contamination has been detected in drinking water, food packaging, and even remote islands, far exceeding European Union and United States standards. With growing concerns about the health and environmental impacts of PFAS, regulatory efforts are being implemented to address and mitigate PFAS pollution, including the Stockholm Convention, which aims to protect human health and the environment from persistent organic pollutants (POPs).

PFAS are toxic and persistent synthetic chemicals

Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals that have been widely used since the 1940s. They possess unique properties such as oil and water repellency, temperature resistance, and friction reduction, making them valuable in various industrial and commercial applications. PFAS can be found in a range of products, from non-stick cookware and fabric treatments to military and industrial uses. PFAS are also present in clothing, furniture, electronics, food packaging, and firefighting foam.

PFAS have gained notoriety as "forever chemicals" due to their exceptional persistence in the environment. They are resistant to breaking down, resulting in widespread contamination of water systems and ecosystems. PFAS have been detected in drinking water, even in remote locations, at levels exceeding international standards. Their persistence has raised significant concerns among scientists and environmentalists, as they negatively impact human health and the ecosystem.

PFAS exposure has been linked to various health issues, including reproductive and developmental problems, liver damage, and immune system disruption. They accumulate in the bodies of living organisms, including humans, and are found in higher concentrations at higher levels in the food chain. The health community remained largely unaware of the toxicity of PFAS until the late 1990s, and concerns have grown due to their persistence and ability to accumulate.

Regulatory efforts are being undertaken to address and mitigate PFAS pollution. The Stockholm Convention on Persistent Organic Pollutants (POPs) aims to protect human health and the environment from these harmful substances. Countries that ratify the convention agree to take measures to eliminate or reduce the release of POPs into the environment. Additionally, the EU Persistent Organic Pollutants (EU POPs) regulation restricts certain PFAS substance groups, and companies must disclose the import, production, and usage of specific PFAS under CEPA 71(1)(b).

PFAS are found in drinking water and food packaging

Per- and polyfluoroalkyl substances (PFAS) are man-made compounds that have been used in a variety of applications since the 1940s, including firefighting, and the stain and waterproofing of consumer products such as carpets, clothing, and food packaging. PFAS are also found in drinking water, with the Illinois Environmental Protection Agency (IEPA) detecting the presence of PFAS in community water supplies in 2021.

PFAS are often found in grease-resistant food packaging, resembling paper or cardboard. PFAS are used to make these materials resistant to heat, water, oil, and corrosion. PFAS have been detected in many types of food packaging, including paper bags for french fries, wrappers for hamburgers, molded fiber salad bowls, and single-use paper plates. Health and environmental advocates are pushing for restricted use of PFAS in food packaging, and some companies have committed to phasing out or reducing PFAS in their packaging.

PFAS exposure has been linked to a range of health problems in humans, including immune system suppression, lower birth weight, high blood pressure, disruption of the endocrine system, changes in liver function, and certain types of cancer. PFAS have been detected in human blood, indicating the potential for accumulation in the body over time. The presence of PFAS in drinking water can also increase the risk of PFAS-related health effects, especially when levels exceed established standards.

To minimize exposure to PFAS, individuals can take steps such as using in-home water treatment technologies like carbon filtration and reverse osmosis to remove PFAS from drinking water. Additionally, consumers can opt for food products packaged in materials with low or no PFAS content, such as those committed to phasing out PFAS.

While efforts are being made to reduce and eliminate the use of PFAS in food packaging and drinking water, it is important for individuals to remain informed and proactive in minimizing their exposure to these harmful "forever chemicals".

PFAS are restricted under EU POPs regulation

Per- and polyfluoroalkyl substances (PFAS) have been widely used since the 1940s due to their unique properties, such as oil and water repellency, temperature resistance, and friction reduction. They are extensively used in a variety of products, from industrial applications to consumer goods. However, PFAS are known as "forever chemicals" due to their persistence in the environment, resulting in widespread contamination of water systems and ecosystems. Studies have linked PFAS exposure to various health issues, including reproductive and developmental problems, liver damage, and immune system disruption.

To address these concerns, the European Union has implemented a comprehensive regulatory framework to manage the risks associated with PFAS. Three PFAS substance groups have been restricted under the EU Persistent Organic Pollutants (EU POPs) regulation. This includes Perfluorooctane sulfonates (PFOS), Perfluorooctanoic acid (PFOA), and perfluorohexane sulfonic acid (PFHxS). These restrictions aim to protect human health and the environment from the harmful effects of PFAS contamination.

The EU POPs regulation is aligned with international commitments under the Stockholm Convention, which includes PFOS and PFOA in its list of targeted chemicals for global elimination. The EU is also considering the inclusion of long-chain perfluorinated carboxylic acids (C9-21 PFCAs) in the Stockholm Convention, further demonstrating its proactive stance in regulating PFAS.

To comply with the EU POPs regulation, manufacturers must identify which components in their supply chain are likely to contain restricted PFAS substances. This crucial first step can be facilitated by data collection services that obtain and validate chemical data from suppliers. Electronics manufacturers, in particular, should take proactive measures to mitigate potential loss of market access due to regulatory violations, as some commonly used electronic components still contain restricted PFAS.

The evolving regulatory landscape for PFAS in the EU presents challenges and opportunities for companies. While the newly proposed restrictions are complex and broad in scope, businesses that proactively adopt safer alternatives to PFAS can gain a competitive edge and ensure continued market access.

PFAS manufacturers concealed health risks

Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals that have been widely used in various industrial and commercial applications since the 1940s. PFAS have unique properties such as oil and water repellency, temperature resistance, and friction reduction, making them valuable in non-stick cookware, fabric treatments, food packaging, and military and industrial uses. However, PFAS have gained notoriety as "'forever chemicals'" due to their persistence in the environment and their ability to accumulate in living organisms, including humans.

PFAS manufacturers have long been aware of the serious health hazards associated with their products but concealed this information from the public. A critical analysis of industry documents revealed that major PFAS manufacturers, including DuPont and 3M, knew about the chemicals' toxicity decades ago but failed to disclose it. This has led to PFAS contamination in water systems, ecosystems, and various consumer products, posing significant risks to human health and the environment.

PFAS exposure has been linked to various adverse health outcomes, including reproductive and developmental problems, liver damage, immune system disruption, increased cholesterol levels, and risk of obesity. Studies have also associated PFAS exposure with cancer (kidney and testicular), hormone disruption, thyroid issues, interference with vaccine effectiveness, and abnormal fetal development. The presence of PFAS in breast milk, umbilical cord blood, and bloodstreams underscores the urgency of addressing PFAS pollution to protect human health, especially that of children.

The widespread use of PFAS in clothing, furniture, electronics, food packaging, and firefighting foam has resulted in their detection in raindrops, leading to contamination from the sky. PFAS are also found in drinking water, soil, air, and food, with levels exceeding standards in remote areas. Electronics manufacturers are now facing the challenge of mitigating potential loss of market access due to regulatory violations regarding restricted PFAS substances in their products.

To address PFAS pollution and protect human health, manufacturers must be transparent and responsible regarding the safety of their products. Regulatory bodies, such as the U.S. Environmental Protection Agency (EPA), are taking action by issuing fines and working to prevent and clean up hazardous PFAS releases into the environment. However, ongoing research is still needed to fully understand the health effects of different levels of PFAS exposure, especially over extended periods.

PFAS are valuable in industrial and commercial applications

Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals comprising thousands of compounds. PFAS have been widely used since the 1940s due to their unique properties, making them valuable in industrial and commercial applications.

PFAS are used in a variety of products, from industrial applications to consumer goods. In industry, PFAS are used in the aerospace, automotive, construction, and electronics sectors. PFAS are also used in clothing, furniture, and food packaging. Their oil and water repellency, temperature resistance, and friction reduction properties have led to their inclusion in non-stick cookware, fabric treatments, and military applications.

PFAS are further used in food processing for their non-stick and grease-resistant properties. The US Food and Drug Administration (FDA) has authorized certain PFAS for use in specific food contact applications. The FDA conducts a rigorous review of scientific data prior to authorizing PFAS for market entry to ensure that there is a reasonable certainty of no harm under the intended conditions of use.
