We hypothesized that exposure to contaminants would be associated with symptoms reported by office workers.
In two mechanically ventilated office buildings in. Montreal, the outdoor air supply was manipulated for 6 weeks, while symptoms were reported and environmental parameters were measured at multiple sites.
Contaminant concentrations varied considerably, in part related to experimental changes in outdoor air supply. Eye symptoms were reported with higher dust and with higher concentrations of nitrogen dioxide. Mucosal symptoms were increased with higher TVOCs, higher nitrogen dioxide, and higher total contaminant load. Systemic symptoms were associated with higher dust levels.
Symptoms reported by the workers were associated with increased concentrations of several contaminants and a summary measure of all contaminants.
我们假设接触污染物与办公室工作人员报告的症状有关。
在蒙特利尔的两座采用机械通风的办公楼中，对室外空气供应进行了6周的操控，同时让工作人员报告症状，并在多个地点测量环境参数。
污染物浓度变化很大，部分与室外空气供应的实验性变化有关。报告有眼部症状时，粉尘及二氧化氮浓度较高。当总挥发性有机化合物、二氧化氮及总污染物负荷较高时，黏膜症状会增加。全身症状与较高的粉尘水平有关。
工作人员报告的症状与几种污染物浓度的增加以及所有污染物的综合指标有关。
