Diesel buses, including NUS shuttle buses, emit fine particles (PM2.5) which are harmful to human health. In this project, we investigated the PM2.5 impacts of NUS shuttle buses and related health effects. Measurement of PM2.5 concentrations was conducted at University Town bus stop during peak (6.00pm to 7.00 pm) and non-peak (2.30pm to 3.30pm) periods for five days. During each period, we used DustTrack, an air quality monitor, and collected 24 data sets with an interval of 2.5 minutes. After applying humidity correction for raw data, we did statistical analysis to find the difference between the level of PM2.5 for peak and non-peak periods. The difference is not significant. Results for the PM2.5 impacts of NUS shuttle buses are inconclusive and further study is needed.
