劣质煤燃烧、吸烟、汽车排放尾气是人体吸入一氧化碳气体的主要来源。当空气中一氧化碳浓度较高时,就将血液中的氧气挤出体内,使得人体缺氧,从而给人的生命带来危害。英国利兹大学的研究团队的研究表明,即使是吸入少量的一氧化碳也存在危险。一些大城市严重堵塞的交通,就是个较大的隐患,因为 Low-quality coal combustion, smoking, car exhaust emissions is the main source of carbon monoxide gas inhalation. When the concentration of carbon monoxide in the air is high, the oxygen in the blood is squeezed out of the body to make the human body lack oxygen, thus bringing harm to people’s life. Research by the research team at the University of Leeds in the UK has shown that even small amounts of carbon monoxide are in danger. Traffic congestion in some major cities is a big problem because
