In May 2015 a survey by the Sydney Fungal Studies Group discovered fungi affected by Rosecomb – a diesel-induced developmental abnormality. The fungi was located in bushland near the current M5E Turrella emission stack – see Rosecomb press release
There is scientific evidence that this abnormality can be caused by exposure to diesel fumes – see Kearney 2009, Umar & Griensven 1999, Flegg 1983
