[Strawbale] Saskatchewan foundations

hi donald, 
I heard you could have gas emissions from car tyres if they are exposed to sun rays, but if they are under a building and covered all around they are quite safe.
but have you got any data about railway sleepers "emissions"??? I know that they use a lot of pesticides along the railway track to control weeds and sleepers themselves are treated with fungicides to avoid rotting. have you got any data about those?
I would like to have more info about this

I think you said at the start that rammed tyres were out due to leaching etc.
I have *never* seen any data on this issue - but I'd like to as I intuitively feel there has to be outgassing or something from tyres.
FWIW, I'm building a 7m x 5m sb (looking to plaster in a few weeks). The foundations are rammed tyres with railway sleepers on top. There is a LOT of work in ramming those tyres...don't underestimate that. If I were to do again, I'd be looking around for alternatives.
