Over 90% of 91 day care centers in greater Montréal, Québec exceeded 1000 ppm of CO2 during January through April 1989. Four variables were independent positive predictors of CO2 levels: the density of children in the center; presence of electric heating; absence of a ventilation system; and building age. High levels of CO2 are associated with respiratory tract and other symptoms. Clear standards and inspection policies should be established for day care center air quality.
1989年1月至4月期间,魁北克大蒙特利尔地区91家日托中心中,超过90%的中心二氧化碳含量超过了1000 ppm。有四个变量是二氧化碳水平的独立正向预测因素:中心内儿童的密度;使用电暖;没有通风系统;以及建筑年代。高浓度的二氧化碳与呼吸道及其他症状有关。应为日托中心的空气质量制定明确的标准和检查政策。
