Two KOALA monitors were installed at the busy intersection of Williamstown Road and Francis Street, Yarraville, Melbourne in early 2020. This location sees heavy traffic including many trucks and container vehicles passing to and from the Port of Melbourne. An added concern has been the proposal to establish a childcare center near this location and the impact that the vehicle-related pollution may have on the health of children.
The findings have shown that, over a complete year of monitoring, the daily average PM2.5 level exceeded the WHO and National Standard of 25 µg/m3 on 39 days. Moreover, the annual average measured was double the regulated value of 8 µg/m3.
The Victorian EPA reported that these values were substantially higher than that measured at their Air Quality Monitoring Station at Footscray, Melbourne.
