Im wondering if they do because someone said they can cause cancer because of this. I tried to research it using google but can't determine an answer from what im reading. Also, do they emit any other things that may be bad for me? Please hurry all u smarties out there. Im freezing in my room but scared to turn new heater on!!
Quartz is the most abundant mineral on the surface of the earth so the little bit you will be using won't affect the environment at all.
