PFOS, its salts and its precursors were used historically as water, oil, soil and grease repellents for carpets, fabric and upholstery and food packaging, and as surfactants in specialized applications such as fire-fighting foams, aviation hydraulic fluids, and fume suppressants for metal plating.

If PFOS is released to the environment it will not be broken down in air. It can travel long distances in the air on particles that eventually fall to the ground. It is not expected to be broken down by sunlight.

So instead of removing HealthCanada created a risk-management strategy which prohibited the production, use, sale and import of PFOS. The federal institution also encouraged the country’s major international trading partners to eliminate the use of PFOS in their products. By 2012, PFOS and PFOA were added to the Prohibition of Certain Toxic Substances Regulations. The primary manufacturer of PFOS, 3M, began a voluntary phase-out of production in 2000 following a series of studies showing significant accumulation in the environment. In 2006, eight major companies followed suit, agreeing to remove PFOS, PFOA and related compounds by 2015 under the guidance of the U.S. Environmental Protection Agency (EPA). Figure 01: Structure of PFOS The chemical formula of PFOS is C 8 F 17 O 3 S. It is a hydrophobic and lipophobic compound similar to other fluorocarbon compounds. But, she says, since PFOS was phased out of production around the year 2000, blood levels have dropped dramatically.
