Sajni’s presentation focuses on the health impacts for people living and working at the northern end of the Roe 9 Tunnel.

Population-based studies show that Diesel Particulate Matter is highly potent and toxic and classified as carcinogenic (Group 1) – meaning it can cause cancer in humans. The combined effect of diesel pollution from Roe 9 tunnel exit stack, trucks idling in gridlock in East Fremantle and the prevailing winds will result in unacceptable Diesel Particulate Matter pollution in densely populated inner urban areas. There is also evidence that Main Roads Noise Management Plan considerably under-estimates the volume of heavy vehicles and that correct noise mitigation measures are not in place for Roe 8. This calls into question what noise mitigation measures are in place to the section of Roe 9 beyond the tunnel and along Stirling Highway to the Port.
