Thanks for the reply. I'd guess you're always going to get side combustion of existing products in the air, you could probably say "methane combustion produces heavy metals" too in that case as there's a chance that there'll be an atom of a heavy metal floating around the intake air. But it's needs to be noted and practical effects considered.

Do they ever burn just methane or do they burn natural gas [that's been somewhat purified]?
I did have a search before posting and found citations claiming natural gas gave significant particulate reduction, as your second citation mentions, ergo the question of whether burning methane made any - it seems primarily to be a factor of burner efficiency, though there's research showing production of fullerenes and nanotubes that probably feeds in here too.
Looking further I found [1] which gives good info, in particular whilst gas:oil is 7:2704 in production of particulates by weight that citation notes that the PM2.5 [small particulates] as opposed to PM10 particulates may be significantly more damaging due to their penetration further in to the respitory system.
