人们担心室外空气污染可能对英国健康产生短期影响。在 1987 年至 1992 年期间进行的一项研究中，研究人员确定臭氧对紧急呼吸系统入院的影响虽小，但影响重大。在当前的研究中，作者调查了 1992 年至 1994 年（含）期间急诊入院与室外空气污染之间的关联，并将结果与早期研究中获得的结果进行了比较。作者在当前的研究中还检测了直径小于 10 μm 的颗粒物 (PM10) 和一氧化碳。控制了适当的混杂因素，例如季节模式、温度和湿度，作者使用泊松回归来估计每日因呼吸系统和心血管疾病而紧急入院的患者与臭氧、二氧化氮、二氧化硫、一氧化碳、黑烟颗粒物和 PM10 之间的关联。研究发现因呼吸系统疾病而紧急入院与 PM10 和二氧化硫之间存在显着的正相关性，但臭氧不存在这种相关性。结果与伦敦早期的结果没有显着差异，并且与北美和欧洲确定的结果具有可比性。心血管疾病与一氧化碳和黑烟有关，但与所研究的其他污染物的关联较弱。
There are concerns about the possible short-term effects of outdoor air pollution on health in the United Kingdom. In a study conducted during the time period between 1987 and 1992, investigators determined that ozone had small, hut significant effects on emergency respiratory admissions. In the current study, the authors investigated associations between emergency admissions and outdoor air pollution for the time period from 1992 to 1994, inclusive, and compared the results with those obtained in the earlier study. The authors also examined particulate matter less than 10 mu m in diameter (PM10) and carbon monoxide in the current study. Appropriate confounding factors, such as seasonal patterns, temperature, and humidity, were controlled for, and the authors used Poisson regression to estimate the association between daily emergency admissions for respiratory and cardiovascular diseases and ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, particles measured as Black Smoke, and PM10. Significant positive associations were found between emergency hospital admissions for respiratory disease and PM10 and sulfur dioxide, but such an association did not exist for ozone. The results were not significantly different from earlier results from London and were comparable with those determined in North America and Europe. Cardiovascular disease was associated with carbon monoxide and Black Smoke, but weaker associations existed with the other pollutants studied.
