近来,有媒体报道称,从市售超越对折的泳衣中检出对健康和环境有害的化学物质全氟化合物(PFCs),其间不少是世界知名品牌。那么,全氟化合物究竟是何物质?国内是否有有关的法规对其进行束缚?记者采访了有关人士。

全氟化合物是一种有着特别特性,可使资料防油、防污和防水的含氟化学物,也是一种很难降解的有机化学污染物。全氟辛酸铵(PFOA)和全氟辛烷磺酸(PFOS)是其间运用范围广,也是具代表性的两种物质。

PFOA and PFOS have high water solubility and are commonly found in a variety of environmental water bodies. When they are ingested by organisms, they will not be enriched in fat tissue, but will be present in the blood after being bound to proteins, and will be present in the blood. Accumulation occurs in liver, kidney, muscle and other tissues, and shows obvious bioaccumulation. �PFOA和PFOS还可形成新生儿的体重下降和体型变小,PFOA能导致内分泌功用紊乱,并存在致癌性,一起和甲状腺疾病也有必定关联� �</p
</p
因为具有防水、抗污的功用,全氟化合物被广泛用于野外的衣物、帐子、睡袋、浴帘、鞋靴、地毯和家私等纺织制品中。

关于媒体曝出的超越对折的泳衣中富含全氟化合物的说法,何璐以为,加工助剂是泳衣制作过程中有能够引进全氟化物的环节� “The use of perfluorinated compounds in swimsuits is often to enhance the water-resistant and anti-fouling functions of swimsuits. Textile companies should pay attention to the waterproof and anti-fouling treatment agents and stain removers used by our company for fabrics.” Based on the harm of perfluorinated compounds to the human body , Deco Nano focuses on C6 finishing agents and fluorine-free products that meet environmental requirements. �</p
</p
因为这些潜在损害的存在,全氟化合物很有能够变成泳衣、野外服装等纺织品的“无形杀手”,其危险危险日渐凸显。
</p
当前,全球已有不少国家出台了相应的法规约束全氟化合物的运用� Sweden notified relevant binding proposals to the World Trade Arrangement in 2005; on June 28, 2013, the Norwegian Environmental Protection Agency announced a national ban on PFOA and its salts and esters in consumer products, and revised the Norwegian Commodity Law accordingly. , and officially came into effect in 2014; Canada Taiwan has enacted the “Perfluorooctane Sulfonate and its Salts and Other Related Compounds Regulations” to prevent people from using and discharging PFOS and its salts, or other compounds and products containing C8F17SO2, C8F17SO3, C8F17SO2N and other groups. causing environmental damage �</p
</p
据悉,2014年版的Oeko-Tex Standard100将全氟化物从其他剩余化学物中移出,独自设为一类,并新增3种全氟酸物质的独自定量。
</p
In addition to the above regulations, perfluorinated compounds are also often controlled in the field of food contact: the EU’s Materials and Substances in Contact with Food Regulation (No. 2004/1935), the German LFGB (LMBG) and the Federal Association for Risk Assessment BfR’s guidance laws BfR section LI, French DGCCRF 2004-64 and British Commonwealth UK SI898:2005 all regulate PFOA. �而国内当前没有出台有关法规强行需求不得运用全氟辛烷磺酸(PFOS)物质以及其他全氟化物� �</p

In this regard, relevant experts suggest that on the one hand, relevant companies should attach great importance to the selection of raw materials, strictly control the quality of upstream raw materials, and strengthen product quality and safety risk assessment; on the other hand, increase cooperation in the development and production of substitute products. research efforts, actively make adjustments in product planning and other aspects to adapt to market changes, and at the same time be highly alert to the resulting quality risk issues
