由于太阳暴晒及发动机散热,紧贴钢板的沥青阻尼片因受热极易分解释放有毒的多环芳烃气体,而且这是一个长期缓慢的释放过程。多环芳烃中间对人体影响最大的是苯并芘(Benzopyrene)。苯并芘是什么?苯并芘(běn bìng pí)是一类具有明显致癌作用的有机化合物。它是由一个苯环和一个芘分子结合而成的多环芳烃类化合物。目前已经检查出的400多种主要致癌物中,一半以上是属于多环芳烃一类的化合物。其中,苯并芘则是一种强致癌物。
As the sun exposure and engine cooling, close to the steel asphalt damping tablets due to heat easily decomposed to release toxic polycyclic aromatic hydrocarbons gas, and this is a long-term slow release process. Polycyclic aromatic hydrocarbons in the middle of the human body most affected by benzopyrene (Benzopyrene). What is benzopyrene? Benzo [a] pyrene is a class of organic compounds with obvious carcinogenic effects. It is a combination of a benzene ring and a pyrene polycyclic aromatic compounds. Of the more than 400 major carcinogens that have been examined so far, more than half belong to the class of PAHs. Among them, benzopyrene is a strong carcinogen.
