摘要

当代社会,车不再高不可攀，它逐渐进入了寻常百姓家。车也不仅仅是一种交通工具,他代表了一种文化、一种生活方式、一种时尚。车轮上的生活是轻快而惬意的,汽车给世界带来了现代物质文明,汽车为人民提供了交通便利,但同时也带来了环境噪声污染等社会问题。也就是在我们享受汽车带来的舒适方便的时候,汽车尾气造成的大气污染、汽车鸣笛造成的噪声污染等影响了人们的生活，人们每天都生活在汽车尾气和汽车噪音中,汽车排放的尾气中含有大量的氮氧化物、碳氢化合物和一氧化碳,对人体危害很大,这些气体排放物不仅气味怪异,而且令人头昏、恶心,影响人的身体健康。可见，汽车尾气已经成为大气污染的首要污染源，控制机动车排放污染已经成为刻不容缓的重要任务。因此,在汽车工业发展和环境保护之间,需要寻找新的平衡。面对这些问题,我们要关注对汽车尾气的处理，关注我们的环境,及时采取措施很好的处理汽车尾气问题，让我们可以与环境和谐相处，让我们可以生活得更美好。
