More rubbish science this morning in the Mail, which really should know better. This time it's a Danish loony who wants to ban open fires and wood burning stoves on health grounds. You need to read the article carefully to discover that he's got absolutely no evidence at all that people are actually harmed by using open fires; he bases his conclusion on two facts he's discovered; that if you drench a petri dish of DNA with wood tar, it dies, and that his sister-in-law, who has a wood burning stove, sometimes gets headaches.
In fact, it's even worse. The loony studied two distinct groups of people from two different areas - those who used wood burning stoves all the time, and those that never did. He found no health differences at all between the two groups - none whatsoever - but rather than being honest enough to admit that wood-burning stoves have no health impact, he twisted the reality in the way that bent, loony scientists do to find that;
1. The wood burning area had more smoke particles in the air
2. If someone breathes in twenty billion trillion smoke particles, they'll get ill.
3. QED - wood burners are a tool of Satan and must be banned
About the only people who give credence to fake science such as this are, unfortunately, the civil servants at the heart of the Central State, who no doubt will now be preparing legislation to ban wood burning stoves.
