Indoor air pollution at a New Zealand urban primary school
1 October 2019
A study of the air quality in a Wellington primary school classroom measured temperature, humidity, carbon dioxide (CO2), nitrogen dioxide (NO2) and particulates. Elements in the particulates were also identified to find the source of the pollution. Fine particulates came largely from the infiltration of outdoor pollutants, particularly motor vehicle emissions from a busy nearby road. Ventilation in the classroom met the internationally recommended figure of 8 litres/second/person only 38% of the time.
