PFASAs

PFASAs is a broad term that can refer to per- and polyfluoroalkyl substances, a large group of human-made chemicals that have been used in industries and consumer products worldwide since the 1940s. These substances are known for their ability to repel water, grease, and stains. They are persistent in the environment and in the human body, meaning they do not break down easily.

Common uses of PFASAs have included non-stick cookware, firefighting foam, food packaging, stain-resistant fabrics, and waterproof clothing. Due to their widespread use and persistence, PFASAs have been detected in soil, water, air, and living organisms, including humans, across the globe.

Concerns about PFASAs stem from their potential health effects. Studies have linked exposure to certain PFASAs with a range of health issues, including effects on the immune system, cholesterol levels, liver enzymes, thyroid hormones, and an increased risk of certain cancers. Regulatory bodies in various countries are increasingly focusing on identifying sources of PFASAs exposure, setting limits for their presence in drinking water, and developing strategies for their remediation. Research into their environmental behavior, human health impacts, and safer alternatives is ongoing.
