This is well off-topic for a climbing forum but I note that others have asked similarly off-topic questions here before and received really helpful and informed replies.
We live by a busy main road. The house is set back around 10m from the road. The noise doesn't normally trouble us too much but I'm increasingly concerned about air pollution. We're currently contemplating some major home improvements (or possibly moving elsewhere - but we like it where we are and need to live near public transport and amenities). I'm keen to find out if the air we breath in the house is significantly polluted - nitrogen oxides and particulates especially.
Does anyone know if it's possible to get the air quality metered, either by buying or renting a suitable metering device, or getting someone in to make measurements? I've had a good look on the web and found nothing very helpful so far.
Any pointers welcome. Many thanks
Martin
