Default Re: Chemicals in coals?

Not sure about infertility, but inhaling carbon monoxide isn't a good thing. The amount inhaled is going to depend on many factors. I know for a fact (according to a CO monitor in my house) that the coals will raise the CO level noticeably and can remain elevated for quite some time, hours in fact. Smoking back to back sessions can raise the CO level to closed to 100 ppm. This is in a closed up house, during the winter time mind you. Proper ventilation would of course reduce the effect.
