| Canada has approved a ban on perfluorooctane sulfonate (PFOS). | NO.28/2008 |
The Canadian government recently approved a proposed regulation issued by Environment Canada on January 9, 2007, banning the use of perfluorooctane sulfonate (PFOS), its salts, and its derivatives in consumer products. This regulation mandates a ban, effective May 29, 2008, on the manufacture, use, sale, supply, importation, and manufacture of products containing PFOS.
This regulation is based on subsection 93(1) of section 319 of the Canadian Environmental Protection Act 1999 (CEPA 1999). It aims to prevent environmental hazards caused by the use of the following substances.
| |   | Perfluorooctane sulfonic acid and its salts |
| |  | Contains C8F17SO2, C8F17SO3Or C8F17SO2N-based compounds |
In Europe, the European Parliament voted in 2007 to adopt the new amendment 2006/122/EC to the EU Dangerous Substances Directive (76/769/EEC), which strictly restricts the market entry and use of perfluorooctane sulfonate (PFOS) and related substances. Member States were required to transpose the directive into their national law by December 27, 2007, and implement the restrictions on June 27, 2008.

Harmful Effects of PFOS
PFOS is a perfluorinated chemical with good heat resistance, resistance to environmental damage, and is also resistant to water and oil. Perfluorinated chemicals accumulate in the fatty tissue of living organisms and are harmful to both humans and wildlife. Evidence suggests that exposure to perfluorinated chemicals, including PFOS, may cause birth defects, adverse effects on the immune system, and damage to thyroid function. During pregnancy, it can also cause developmental problems in the infant. The U.S. Environmental Protection Agency considers occupational exposure to PFOS to be linked to bladder cancer.
Applications of PFOS
| 1. | For surface treatment: stain, oil and water resistance for personal clothing, home décor, and automotive interiors. |
 |
| 2. | Used for paper protection: As part of the pulp forming process, it ensures the oil and water resistance of paper and paperboard. |
 |
| 3. | Performance chemicals: Widely used in specialized industrial, commercial, and consumer sectors. Special applications include fire-retardant foams, surfactants for mining and oil wells, acid mist suppressants for metal plating and electronic etching tanks, photolithography, electronic chemicals, hydraulic fluids, alkaline cleaners, floor polishes, photographic film, denture cleaners, shampoos, chemical mediators, coatings, carpet stain removers, and insecticides that can also be used as poison baits. |
