Relationship between Air Pollution Exposure in Daily Travelling Activities and Health Impact on Primary School Children

This study relates to the pulmonary function of school age children and the air quality of public transport in Hong Kong. It focuses on selected primary five or six students from schools in Hong Kong. A log book and a questionnaire were distributed through the schools to and completed by these students. Each sampled student had to fill in the daily travelling activities and also required to answer questions related to their indoor living conditions. The sampled students were required to conduct a pulmonary function test. The air pollutants such as PM10, PM2.5, CO2, CO and Volatile Organic Compounds (VOCs) were measured following the routes to school and return home of sampled students. A statistical analysis, ANOVA, was performed on the modes of transportation and the lung function test results
