1. How toxic or harmful is burnout smoke.

Sources checked include the State of Knowledge Report: Air Toxins and Indoor Air Quality in Australia 2001 (Environment Australia), Dangerous Properties of Industrial Material 9^th Ed. 1998 (Sax, I. and Lewis, R.) and Medline. In addition to this the ACT Fire Brigade, ACT Workcover, Environment ACT, Poisons Information, and NSW Health were all consulted.

2. What is the (a) volume and (b) frequency of burnout smoke which spectators are exposed to over the three days at Summernats.

It is not possible to estimate the volume and frequency of burnout smoke, as they were not measured. The volume and frequency are also highly dependable on factors such as engine size of the cars, the tyres fitted to the cars, the drivers' skill and wind direction.
