PFOA and PFOS belong to the Perfluorinated alkylated substances PFAS group of chemicals. The PFOA stands for Perfluorooctanoic acid, whereas PFOS stands for Perfluorooctane sulfonate. Due to the unique abilities of PFOA and PFOS to repel water and oil, these artificial chemicals are utilized in several industrial applications and products. Examples of these products are non-stick cookware, food wraps, stain repellents, and fire-repellent foams which possess a heavy dose of PFOA and PFOS. Lets explore more about PFOA and PFOS.

This post introduces PFOA and PFOS, their impact on human health, and methods to remove them from drinking water.
