Perfluorooctane sulfonates (PFOS) is a fluorinated surfactant that is widely used as a raw material in textiles, carpets, coatings, fire-fighting foams, aviation hydraulic fluids, etc. because of its oil and water repellency. Since PFOS was recognized as a substance harmful to human health by the EU Health and Environment Risk Scientific Committee, on December 27, 2006, the European Parliament and the Council of Ministers jointly issued the "Directive on Restricting the Sale and Use of PFOS" (2006). /122/EC), This Directive stipulates that it is not allowed to sell finished products, semi-finished products and parts that contain PFOS concentrations of 0.1% or more. The transition period is 18 months. This EU resolution is referred to as the “PFOS ban†and will come into effect on June 27, 2008.
In China, PFOS exists in some additives and dyes. It mainly produces plastic-related products such as plastics, plastic foams and foaming agents. According to the staff of Germany's Heinstein Institute in China, there are coated or coated products in textiles and clothing, such as thermoplastic shirts, non-slip plastic in antiskid socks and PVC products containing PFOS. Possibility and excess risk are greater, and textiles that are commonly printed and dyed are less likely to contain PFOS. For this reason, I will remind the exporting EU companies to conduct self-examination on the products involved and avoid possible losses.
PFOS limit instruction content
1. Limit the use of PFOS products and market launches. Do not sell substances whose concentration or mass is equal to or greater than 0.005% with PFOS as a constituent substance or element.
2. Limit the use of PFOS in finished and semi-finished products. Do not sell finished products, semi-finished products and parts that contain PFOS concentrations or have a mass equal to or greater than 0.1%. The scope of the directive includes all products that are intentionally added to PFOS, including the surface of layers used in specific parts and products, such as textiles. However, the restrictions apply only to new products, and there are no restrictions on products that are already in use and on the secondary market.
3. Evaluate the instructions. To phase out the use of PFOS, when there are new situations or safe alternatives, the scope of the directives should be evaluated.
4. There are some exceptions:
(1) The directive states that, according to SCHER's confirmation, PFOS is now used prudently in the aviation industry, semiconductor industry and imaging industry. If there is a small amount of PFOS released into the environment and exposed to the workshop, there will be no association with the environment and humans. Hazard, so photoresists, photolithographic coatings, aviation hydraulics, etc. do not apply this directive;
(2) Regarding the issue of fire-fighting foam, SCHER agreed that it should first analyze the hazards of its substitute products before making a final decision;
(3) With regard to limiting the application of PFOS in the coating industry, SCHER agrees that if effective methods cannot be found to reduce emissions from metal coating processes to significantly lower levels, the use of PFOS in the industry will be limited in the future, but At this stage, the most advanced technology must be applied to minimize the emission of PFOS in industrial electroplating.
5. PFOA may also be limited in the future. The directive states that perfluorooctanoic acid (PFOA) is suspected to have a similar hazard to PFOS, and is still assessing its risk analysis tests, the effectiveness of alternatives, and restrictions.
Order implementation schedule
1. The directive takes effect on the date of publication, that is, on December 27, 2006;
2. Each member shall convert the directive into its domestic law by December 27, 2007. Each Member State shall submit the text of the proposed measures to the European Commission and set out the relevance of the measures to be taken and the content of the directives;
3. Each member country shall start implementing restrictions on June 27, 2008;
4. The fire-fighting foam that has been put on the market on December 27, 2006 can continue to be used until June 27, 2011;
5. Prior to December 27, 2008, member states should publish: (1) Specific measures aimed at reducing the use of PFOS in the electroplating industry; and (2) Fire-fighting foam containing PFOS in stock.
