昨天，市政协港澳台侨工作顾问、万科集团副总裁毛大庆在微博上称，石棉刹车片的摩擦材料会释放出纳米级的重金属颗粒，吸入肺部会导致肺癌，也是重要空气污染源。而北京有500万辆车，每辆车有4个刹车片，一年能产生几万吨的纳米级有害粉尘。该消息引发网友热议。

yesterday,The CPPCC, macaw, consultant work/Vanke vice President MaoDaQing in micro bo said,Asbestos brake lining friction material releases the nanoscale heavy metal particles,Suction lung can cause lung cancer,Air pollution is also important.But Beijing has 5 million vehicles,Every car has four brake pads,A year can produce tens of thousands of tons of nanoscale harmful dust.The news caused net friend of hot debate.

　　针对网友的质疑，毛大庆昨晚向记者坦陈，关于所列数据，只是他转述的专家观点，希望借此提出呼吁。他说，该信息来源于与相关环保、医学专家的多次交流，“其中有协和医科大学的专家，还有中国工程院的院士，来源绝对靠谱。根据研究，石棉刹车片磨损产生的微颗粒，与

For users to question,Last night that MaoDaQing to reporters,Listed on the data,But he retails experts point of view,Hoping to appeal.He said,The information comes from and related environmental protection/Medical experts multiple communication,"One union medical university experts,And an academician of the Chinese academy of engineering,Source absolutely by spectrum.According to the,Asbestos brake shoes wear of the micro particle,and

　　他还透露，我国曾于2003年向世界承诺，遵照国际标准，禁用石棉刹车片，“事实上，发达国家早就改用有机复合材料，比如陶瓷刹车片了。国家应该按照标准办事，有令必行，有禁必止。”

　　石棉制品国际禁用我国商用车仍在使 Asbestos products in our country is still in the international banned commercial vehicle make

　　一位不愿公开姓名的知名汽车行业分析师表示，刹车片在工作过程中会摩擦产生粉尘，释放有害物质污染环境。无论是鼓式刹车片，还是盘式刹车片都会产生粉尘，在目前的技术条件下无法解决这一污染源。

One does not wish to open name famous auto industry analysts said,Brake pads in the work process will produce friction dust,Release harmful substances from polluting the environment.Whether drum brake pads,Or brake pad can produce dust,In the present technical conditions to solve the pollution sources.

　　无石棉刹车片的成本要比石棉刹车片高出30%。由于成本低、重量轻，很多车企在生产货车、工程车之类的商用车时，仍在使用含石棉刹车片。由于国际上许多国家已经禁止使用石棉制品，我国刹车片出口受到了严重阻碍。曾经有一家企业出口一批半金属刹车片到美国，由于他们产品的辅料里含有石棉成分，被全部退回。(记者刘佳 刘磊涛)
