3月的京城已经春意盎然,可有时天公却偏偏不作美。3月20日,一场罕见的沙尘暴横扫华北大地,搞得北京天昏地暗,到处充满了尘土,让人们喘不过气来。沙尘暴使能见度大大降低,极易导致交通延误及恶性交通事故,更重要的是它还会对人们的身体健康造成较大的伤害。究竟沙尘暴对人体有什么危害,人们又该怎样防护呢?首都医科大学附属北京朝阳医院——北京市呼吸疾病研究所主任医师王浩彦就这些大家关心的问题做了解答。 In March the capital has been full of spring, but sometimes the heavenly public but unpleasant. On March 20, a rare sandstorm swept through the North China earth, making Beijing dusk and darkness full of dust and letting people breathe it. Dust storms greatly reduce visibility, can easily lead to traffic delays and vicious traffic accidents, more importantly, it will also cause greater harm to people’s health. What exactly do the sandstorms do to the human body and how should they be protected? Wang Haoyan, chief physician of the Beijing Institute of Respiratory Diseases, Beijing Chaoyang Hospital affiliated to the Capital Medical University, responded to these questions of concern to all.
