Kawaguchi and Hatogaya City are located on the northern edge of Tokyo. We analysed between air pollution and prevalence rate of allergic diseases among elementary school children in this area. A prevalence rate of allergic diseases in 1996 May and June was as follows; bronchial asthma 13.5%, atopic dermatitis 24.5%, allergic rhinitis and/or conjunctivitis 22.8%, urticaria 12.4%, food allergy 7.8% and drug allergy 2.2%, respectively. Air pollution of this area was analysed to check the levels of nitrogen dioxide (NO2), sulfur dioxide (SO2) and suspended particulate matters (SPM). NO2 pollution was relatively high in urban area, and SPM pollution was especially high around the highways. SO2 pollution was lower than the environmental standard. No relationship was found between the prevalence rate of bronchial asthma, atopic dermatitis, allergic rhinitis and/or conjunctivitis and air pollution, but it was found that these diseases are slightly related to population density (p < 0.1, p < 0.01, p < 0.1, respectively).
川口市和羽鸟市位于东京的北部边缘。我们分析了该地区小学生的空气污染与过敏性疾病患病率之间的关系。1996年5月和6月过敏性疾病的患病率如下：支气管哮喘为13.5%，特应性皮炎为24.5%，过敏性鼻炎和/或结膜炎为22.8%，荨麻疹为12.4%，食物过敏为7.8%，药物过敏为2.2%。分析该地区的空气污染情况以检测二氧化氮（NO2）、二氧化硫（SO2）和悬浮颗粒物（SPM）的水平。市区的二氧化氮污染相对较高，高速公路周边的悬浮颗粒物污染尤其严重。二氧化硫污染低于环境标准。未发现支气管哮喘、特应性皮炎、过敏性鼻炎和/或结膜炎的患病率与空气污染之间存在关联，但发现这些疾病与人口密度存在轻微关联（分别为p < 0.1、p < 0.01、p < 0.1）。
