环境空气污染被认为是对暴露人群造成健康危害的潜在环境风险因素之一，这在以前的许多研究中得到了证明。一些纵向、生态和流行病学研究表明，室外大气污染物的室外水平与不利的健康影响之间存在关联，特别是与呼吸系统和心血管系统住院有关。这项工作的目的是通过普通最小二乘线性回归来评估大气污染物对里斯本医院入院的影响。污染物（CO，NO，NO2，SO2，O-3，PM10和PM2.5）从葡萄牙环境局的13个监测站，提供每小时的观测。从卫生系统中央管理局收集住院数据，并按年龄汇编：< 15岁、15-64岁、> 64岁。研究期间为2006-2008年。结果显示，以下各项之间存在显著的正相关：（1）15至64岁年龄组的污染物CO、NO、NO2、SO2、PM10和PM2.5以及循环系统疾病（0.5%的住院率（HA）增加10 μ g/m（-3）NO增加）和64岁以上（1.0%的中风入院率随着10 μ g m（-3）NO2的增加而增加）;（2）15岁以下的污染物CO、NO、NO2、SO2、PM10和PM2.5以及呼吸系统疾病（3）64岁以上老年人的污染物NO、NO2和SO2以及呼吸系统疾病（10 μ g/m3 CO增加，HA增加1.3%）。
Ambient air pollution is recognised as one of the potential environmental risk factors causing health hazards to the exposed population, demonstrated in numerous previous studies. Several longitudinal, ecological and epidemiological studies have shown associations between outdoor levels of outdoor atmospheric pollutants and adverse health effects, especially associated with respiratory and cardiovascular hospital admissions. The aim of this work is to assess the influence of atmospheric pollutants over the hospital admissions in Lisbon, by Ordinary Least Squares Linear Regression. The pollutants (CO, NO, NO2, SO2, O-3, PM10 and PM2.5) were obtained from 13 monitoring stations of the Portuguese Environmental Agency, which provide hourly observations. Hospital admission data were collected from the Central Administration of the Health System and were compiled by age: < 15, 15-64, > 64 years old. The study period was 2006-2008. Results showed significant positive associations between the following: (1) the pollutants CO, NO, NO2, SO2, PM10 and PM2.5 and circulatory diseases for ages between 15 and 64 years (0.5 % hospital admissions (HA) increase with 10 mu g m(-3) NO increase) and above 64 years (1.0 % stroke admission increase with 10 mu g m(-3) NO2 increase); (2) the pollutants CO, NO, NO2, SO2, PM10 and PM2.5 and respiratory diseases for ages below 15 years (up to 1.9 % HA increase with 10 mu g m(-3) pollutant increase); and (3) the pollutants NO, NO2 and SO2 and respiratory diseases for ages above 64 years (1.3 % HA increase with 10 mu g m(-3) CO increase).
