| − | Asbestos is a silicate mineral fiber itself does not contain toxic chemicals, its greatest hazard from asbestos fibers, which is a very fine fibers is almost invisible to the naked eye, it was reported: 1 kg asbestos containing about 100 ten thousand yuan fiber. Yuan fiber diameter of 0.5 microns, 5 microns in length, a few weeks or even a few months can be suspended in the atmosphere and water. We are talking about PM2.5 refers to a diameter less than or equal to 2.5 micron particles suspended in the atmosphere, and the asbestos the yuan fiber than PM2.5 also tiny addition to the asbestos mining industry and asbestos processing industry, auto repair asbestos pollution damage maximum occupational one, especially in the past the use of asbestos brake pads, the hub will accumulate a large number of asbestos debris flying everywhere, repair the brake system. When these small fibers are sucked into the human body, will be deposited in the lungs will eventually form asbestosis. Asbestos fibers can also lead to gastrointestinal cancer, mesothelial cancer - pleural or peritoneal cancer. The symptoms of asbestos-related diseases, there is often a long incubation period, after about 10-20 years, and even some 40 years of exposure to asbestos may appear according to the composition and structure of asbestos is generally divided into three categories: amphibole asbestos (blue asbestos), chrysotile and brucite asbestos. "Carcinogenic asbestos" mainly refers to the amphibole asbestos, most countries in Western Europe since the 1980s to prohibit the application of amphibole asbestos products, China is also all amphibole asbestos mines closed in the 1980s. The vast majority of the development and application of asbestos and its products in the international chrysotile, but later began to limit the United States in 1971 to restrict the use of asbestos chrysotile, in 1992, a total ban on the production and use of asbestos and asbestos products in 1998 World WHO reiterated that the carcinogenic effects of chrysotile asbestos, lead to the risk of mesothelioma especially called for the use of alternatives, many countries have opted for a total ban on use of asbestos products in Australia in 1991, a total ban on asbestos-containing materials, and some The report said the ban on the import or use of asbestos since 2004. The EU requires all member states to pass legislation before the end of 2004 to disable asbestos instruction.

| − | Japan since 2008, South Korea from 2009 full of asbestos products banned WTO in March 2001 for France and Canada disputes that chrysotile asbestos has been identified as carcinogens, asbestos manufacturers adhere to the safety limit does not exist, the various Member States shall prohibit the use or import of asbestos-containing material most of the asbestos resources for the construction industry, automotive industry application followed in asbestos gaskets, seals, brake friction materials has long been in use. According to the International Ban Asbestos Secretariat of the Organization (IBAS), in 2006, China is the world's largest asbestos consumer, the third largest asbestos-producing countries (ranked in Russia, Kazakhstan). With the improvement of domestic and international legislation, the export environmental policy "barriers", non-asbestos imminent. The dealer said: asbestos gasket applications in multiple parts of the Great Wall Motor. SA220 models (SAILOR) 17, including the cylinder Gaskets, exhaust pipe, throttle. V240 and X240 two cars 9. Tiggo, A3 RHD car exhaust pipe gasket and intake manifold tablet contains trace amounts of asbestos material gaskets are installed inside the body, and passengers do not pose a health threat, but great harm to the maintenance personnel Great Wall said: in April 2012, has been to stop the use of asbestos materials. The recall is caused because the number of error components in domestic production, leading to the logistics aspects of the error distribution, which mistakenly attached to the batch of products sold in Australia, resulting in the batch product does not comply with local laws, Chery said: domestic project started in the 1990s to study non-asbestos gasket material, after years of efforts, has been successfully developed, but some companies on the domestic market will contain some amount of asbestos gasket (5-20%), referred to as non-asbestos gasket , 100% asbestos-free gasket was known as non-asbestos gasket. This is reminiscent of the the concept pure milk debate a few years ago, the enterprise but by means of the confusion this should not occur doubt, violations of the rights and interests of consumers therefore like to take this opportunity in the domestic legislation prohibit motor vehicles and parts, but face asbestos-containing products.
