本世纪五十年代以来,肺癌的发病率在全球范围内急剧升高;受大气飘尘污染城市高于农村的现象也日见显著。各家学者一致认为,粒径越少的飘尘颗粒吸附有害物质越多,对人体危害也就较大。有关部门曾对银川市总悬浮颗粒的重量分布进行过监测。但对本课题所涉及内容未见有报道。为探讨银川市区大气飘尘粒径分布规律及其对人体的潜在危害,作者等于1986年春末在若干功能
Since the 1950s, the incidence of lung cancer has risen sharply around the world; the phenomenon of cities being contaminated by airborne dust is higher than that in rural areas is also becoming increasingly prominent. Various scholars agree that the smaller the particle size of the fly ash particles adsorbed more harmful substances, the greater harm to the human body. The relevant departments once conducted a survey on the weight distribution of total suspended particles in Yinchuan. However, the topics covered in this topic have not been reported. In order to explore the distribution rules of atmospheric dust particle size in Yinchuan and its potential harm to the human body, the author is equal to the late spring of 1986 in a number of functions
