., another suggestion: Home Depot has Home Decorators bamboo by the pallet: it is a nice color (not too dark not too light), not really out-gassing, it is a 2-2.5 on the 1-5 hardness scale, it does not split that easy and is not involved in the formaldehyde lawsuits that lumberliquidators had for the similar bamboo...price is between hardwood and laminate.i'm on the first floor and i got this sandwich: concrete floor, 2x paint membrane, glued 6 mm cork, 3/4" plywood screwed into concrete, tar paper, bamboo on top nailed in.

It seems that Vinyl floors are highly toxic since they are made of PVC, Laminate flooring also toxic since they have formaldehyde and carpets are also toxic since they have fire retardants and stain resistant chemicals.

FYI Interesting segment on 60 Minutes tonight on Lumber Liquidators - Chinese made floor boards with very high levels of formaldehyde.

Airing out will do wonders and new flooring will have it's own smell as well, can't beat formaldehyde for hiding other issues.

You should always vent a gas stove due to the pollutants that they emit (nitrogen dioxide, carbon monoxide and formaldehyde). 

Asbestos probably is on site, Lead paint for sure, formaldehyde in insulation...radon if there is a basement. 

if they catch fire they incinerate anything in side.. the insulation has formaldehyde in it etc. 

And PLEASE do your due diligence and don't but any wood that you can't get certified Formaldehyde free or within  California standards.
