PFAS Testing

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been widely used in various industrial and consumer products since the 1940s. Known for their resistance to heat, water, and oil, PFAS are often referred to as “forever chemicals” due to their persistent nature in the environment and human body. These substances are commonly found in products such as non-stick cookware, water-repellent clothing, stain- resistant fabrics, food packaging, and firefighting foams.

Given their widespread use, PFAS contamination has emerged as a significant environmental and public health concern. Studies have linked PFAS exposure to various health issues, including hormonal disruption, immune system impacts, and increased risks of certain cancers. As regulatory scrutiny intensifies, accurate testing and analysis of PFAS in various matrices become essential for compliance and safety.

Human Exposure to PFAS

People can be exposed to PFAS through several pathways, primarily due to the widespread use of these chemicals in various products and industrial processes. Here are the main routes of exposure:

Contaminated Water

Drinking Water: One of the most common sources of PFAS exposure is through contaminated drinking water. PFAS can leach into groundwater from industrial sites, landfills, and wastewater treatment plants, affecting nearby water supplies.
Surface Water: Recreational activities involving lakes, rivers, and other bodies of water can also lead to exposure if these sources are contaminated.

Food Sources

Food Packaging: PFAS are often used in food packaging materials, such as microwave popcorn bags, fast-food wrappers, and pizza boxes, leading to potential leaching into food.
Contaminated Food: Foods grown in soil or water contaminated with PFAS can also be a source of exposure. This includes fish and shellfish from contaminated waters.

Consumer Products

Household Items: Many everyday products contain PFAS, such as non-stick cookware, stain-resistant fabrics, water-repellent clothing, and cleaning products.
Personal Care Products: Some cosmetics and personal care items, such as lotions and shampoos, may contain PFAS.

Occupational Exposure

Workers in industries that manufacture or use PFAS, such as chemical production, firefighting foam, or textile manufacturing, may face higher exposure levels.

Indoor Air and Dust

PFAS can also be found in indoor air and dust, particularly in homes with products that contain these chemicals. This can lead to inhalation or ingestion through household dust.

Soil and Agricultural Exposure

PFAS can accumulate in soil, particularly near industrial sites or areas where firefighting foams have been used. Agricultural practices may lead to the uptake of PFAS by crops.
