< p > recently, media reports reported that more than half of the a href= "http://m.pmae.cn/news/index_f.asp" > swimwear < /a > were detected in the market, which were harmful to health and environment, and many of them were internationally famous brands. What is the substance of perfluorinated compounds? Are there any relevant laws and regulations to restrict them? Reporters interviewed relevant people. < /p >
< p > according to He Lu, Zhejiang Hangzhou HECO Detection Technology Co., Ltd., perfluorinated compounds are a kind of fluorine containing chemicals with special characteristics, which can prevent oil, antifouling and waterproofing, and are also a kind of organic chemical pollutants which are difficult to degrade. Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are the two most widely used and the most representative ones. < /p >
< p > PFOA and PFOS are highly water-soluble and widely exist in many kinds of environmental water bodies. When they are ingested by organisms, they will not be enriched in adipose tissue, but they will exist in blood after binding with proteins and accumulate in tissues such as liver, kidneys and muscles. PFOA and PFOS can also cause neonatal weight loss and body size reduction, PFOA can lead to endocrine dysfunction, and carcinogenicity, and thyroid disease is also related. < /p >
"P >" because of its waterproof and anti fouling functions, perfluorinated compounds are widely used in outdoor clothes, tents, sleeping bags, shower curtains, < a target= "_blank" href= "http://m.pmae.cn/" > shoes < /a > boots, carpets and furniture, etc. a target= "_blank" href= "target=" > textile > finished products. He Lu said. < /p >
< p > for media coverage of more than half of the swimsuits containing perfluorinated compounds, He Lu thinks that processing aids are the most likely to introduce perfluorides in the manufacture of swimsuits. "The use of perfluorinated compounds in swimsuits is often aimed at enhancing the water resistance and anti fouling properties of swimsuits. Textile enterprises should pay attention to the waterproofing and antifouling agents and detergents used by our enterprises." < /p >
< p > because of these potential hazards, perfluorinated compounds are likely to become "invisible killers" of swimsuits and outdoor a target= "_blank" href= "http://m.pmae.cn/" > clothing "/a" and so on, and their hidden dangers are becoming increasingly prominent. < /p >
At present, many countries in the world have promulgated corresponding laws and regulations to restrict the use of perfluorinated compounds. P In 2005, Sweden informed the World Trade Organization of the relevant restrictive proposals; in June 28, 2013, the Norway Environmental Protection Bureau announced the national ban on perfluorooctanoic acid (PFOA) and its salts and esters in consumer products, and amended the Norway product law, and entered into force in 2014. Canada promulgated the regulations on perfluorooctane sulfonate and its salts and other related compounds to prevent environmental hazards caused by the use and discharge of PFOS and its salts, or other compounds and products containing C8F17SO2, C8F17SO3, C8F17SO2N and other products. < /p >
< p > it is reported that the 2014 version of Oeko-Tex Standard100 removes all fluoride from other residual chemicals and is set up separately and adds 3 separate limits of perfluoroacids. < /p >
< p > in addition to the above regulations, perfluorides are also frequently controlled in the field of food contact: the EU's food and material law (No.2004/1935), Germany LFGB (LMBG) and the federal Risk Assessment Association BfR formulated guidelines for BfR section LI, France French DGCCRF 2004-64, and the British federal UK, etc. At present, there are no relevant laws and regulations for compulsory use of perfluorooctane sulfonate (PFOS) and other perfluorides. < /p >
< p > for this reason, the relevant experts suggest that the relevant enterprises should attach great importance to the selection of raw materials, strictly check the quality of upstream raw materials, strengthen the risk assessment of product quality and safety; on the other hand, increase the capability of cooperation in the fields of R & D, production and replacement products, and make active adjustments in product design to adapt to the changes of < a href= "http://m.pmae.cn/news/index_s.asp" > market /a > at the same time, and be vigilant against the quality risks arising therefrom. < /p >
