Researchers at Thessaloniki's Aristotle University have warned that excessive use of fireplaces instead of other forms of heating creates dangerous pollution inside homes, saying that microparticles in closed spaces can exceed maximum safety levels set by European authorities within just two or three hours of lighting a fire.
