In this paper, we examine the role that ambient air pollution plays in exacerbating cardiovascular and respiratory disease hospitalization in London, Ontario from 1 November 1995 to 31 December 2000. The number of daily cardiac and respiratory admissions was linked to concentrations of air pollutants (sulphur dioxide, nitrogen dioxide, ozone, carbon monoxide, coefficient of haze, PM(10)) and weather variables (maximum and minimum of temperature and humidity). Results showed that current day carbon monoxide and coefficient of haze produced significant percentage increase in daily cardiac admissions of 8.0% (95% CI: 1.5-11.5%) and 5.7% (95% CI: 0.9-10.8%) for people < 65 years old. PM(10) was found to be significantly associated with asthma admission in the > 65 group, with percentage increase in cardiac admission of 25% (95% CI: 2.8-52.3%) and 26.0% (95% CI: 5.3-50.9%) for current day and 2-day means, respectively.
在本文中，我们研究了1995年11月1日至2000年12月31日期间，安大略省伦敦市环境空气污染在加剧心血管和呼吸系统疾病住院方面所起的作用。每日心脏和呼吸疾病入院人数与空气污染物（二氧化硫、二氧化氮、臭氧、一氧化碳、雾霾系数、PM(10)）浓度以及天气变量（最高和最低温度及湿度）相关联。结果显示，当日一氧化碳和雾霾系数使65岁以下人群的每日心脏疾病入院人数显著增加，分别为8.0%（95%置信区间：1.5 - 11.5%）和5.7%（95%置信区间：0.9 - 10.8%）。研究发现，PM(10)与65岁以上人群的哮喘入院显著相关，当日和两日均值的心脏疾病入院人数分别增加25%（95%置信区间：2.8 - 52.3%）和26.0%（95%置信区间：5.3 - 50.9%）。
