Classroom carbon dioxide concentration, school attendance ...

Background: We tested the hypothesis that classroom carbon dioxide (CO2 ) concentration is inversely related to child school attendance and educational attainment. Methods: Concentrations of CO2 were measured over a 3-5 day period in 60 naturally ventilated classrooms of primary school children in Scotland. Concentrations of CO2 were related to the class average annual attendance and ...
