Due to their widespread use, PFAS/PFOS can be found in many environments and products we encounter daily:
A. Drinking Water
PFAS/PFOS can contaminate drinking water in several ways:
- Industrial Discharges: Factories that produce or use PFAS/PFOS may release these substances into wastewater, which can then flow into rivers and lakes, eventually making its way into our drinking water supply.
- Soil Leaching: PFAS/PFOS present in the soil can seep into groundwater, contaminating sources of drinking water.
- Firefighting Foams: Firefighting foams used to combat large-scale fires may contain PFAS/PFOS, which can then enter the environment and contaminate drinking water.
B. Food
- Food Packaging: PFAS/PFOS are used to make food packaging waterproof, including fast-food paper bags, microwaveable containers, and food wrap.
- Fish: Fish can be contaminated by PFAS/PFOS present in the water they swim in.
- Fruits and Vegetables: Fruits and vegetables can be contaminated by PFAS/PFOS in irrigation water or soil.
C. Clothing and Textiles
- Waterproof Clothing: Rain jackets, hiking boots, and other waterproof clothing are often treated with PFAS/PFOS to make them water-resistant.
- Carpets and Rugs: PFAS/PFOS can be used to treat carpets and rugs to make them stain-resistant.
D. Kitchenware
- Non-Stick Pans: PFAS/PFOS are used in the non-stick coating of pans and other kitchen utensils.
- Aluminum Foil: Aluminum foil may contain PFAS/PFOS.
E. Cosmetics
- Makeup: Some makeup products, such as mascara and lipstick, may contain PFAS/PFOS.
- Hair Products: Certain hair products, like shampoos and conditioners, may contain PFAS/PFOS.
F. Furniture
- Sofas and Chairs: PFAS/PFOS can be used to treat the fabrics of sofas and chairs to make them stain-resistant.
- Wooden Furniture: PFAS/PFOS can be used to waterproof wooden furniture.
G. Cleaning Products
