Abstract

This study analyzed indoor air pollutants from elementary school with different environment. Air sampling and measurement were carried out from classrooms and hallways from three target elementary schools in the fall and winter seasons. The winter average concentrations of $PM_{10}$, $CO_2$, CO, aldehydes and ketones, and benzene were higher than the fall ones. The fall average concentrations of $O_3$ and $NO_2$ were higher than the winter ones. The concentrations of $PM_{10}$ and $CO_2$ at the schools near the heavy traffic areas and having poor ventilation were higher than those from the other elementary school. The average concentration of CO at the school having heavy traffic volume was highest. The concentrations of $O_3$, $NO_2$, aldehydes and ketones, and VOCs at the school near the shipbuilding industries were highest among the three elementary schools.
