9. 9 What have the results told us? Diesel PM – primary source of cancer risk Diesel PM – primary source of cancer risk Directly emitted PM and secondary PM from NOx – primary source of noncancer risk Directly emitted PM and secondary PM from NOx – primary source of noncancer risk Mobile sources predominate region impact Mobile sources predominate region impact Other toxics play a role in near source risk Other toxics play a role in near source risk

10. 10 What are the risks? High traffic freeways: 300-1,700/million High traffic freeways: 300-1,700/million 4
