在西澳大利亚州的珀斯进行了一项病例交叉研究，以调查每日空气污染物浓度与选定疾病类别的每日住院率之间的关系。每日测量的颗粒物（测量浊度法和PM2.5），光化学氧化剂（测量臭氧），二氧化氮（NO2）和一氧化碳（CO）的浓度从1992年至1998年通过一个大都市网络的监测站。每日PM2.5浓度是使用监测数据、建模和插值估算的。获得了呼吸系统、心血管（CVD）、胃肠道（GI）疾病、慢性阻塞性肺疾病（COPD）（不包括哮喘）、肺炎/流感疾病和哮喘的医院发病率数据，并将其分类为所有年龄组（15岁以下和65岁以上）。胃肠道发病率用作对照疾病。采用条件Logistic回归分析数据。结果表明，少量的显着关联的颗粒物浓度，二氧化氮和一氧化碳的呼吸系统疾病，CODP，肺炎，哮喘和CVD住院的每日变化。臭氧浓度的变化与任何疾病结果均无显著相关性。这些数据提供了有用的数据，说明在二氧化硫浓度极低和二氧化氮浓度较低的空气区，空气污染对健康的潜在影响，这在许多其他城市是常见的。
A case-crossover study was undertaken to investigate the relationship between daily air pollutant concentrations and daily hospitalizations for selected disease categories in Perth, Western Australia. Daily measurements of particles ( measured by nephelometry and PM2.5), photochemical oxidants ( measured as ozone), nitrogen dioxide (NO2) and carbon monoxide (CO) concentrations were obtained from 1992 to 1998 via a metropolitan network of monitoring stations. Daily PM2.5 concentrations were estimated using monitored data, modelling and interpolation. Hospital morbidity data for respiratory, cardiovascular (CVD), gastrointestinal (GI) diseases, chronic obstructive pulmonary diseases (COPD) excluding asthma; pneumonia/influenza diseases; and asthma were obtained and categorized into all ages, less than 15 years and greater than 65 years. Gastrointestinal morbidity was used as a control disease. The data were analyzed using conditional logistic regression. The results showed a small number of significant associations for daily changes in particle concentrations, nitrogen dioxide and carbon monoxide for the respiratory diseases, CODP, pneumonia, asthma and CVD hospitalizations. Changes in ozone concentrations were not significantly associated with any disease outcomes. These data provide useful information on the potential health impacts of air pollution in an airshed with very low sulphur dioxide concentrations and lower nitrogen dioxide concentrations commonly found in many other cities.
