It's been responsible for many thousands of deaths in the 1950's and 1960's (due to breathing difficulties), until the introduction of smoke free coal.
On a different note, I remember many years ago, being in the viewing lounge at BHX on bonfire night. There was a Lufthansa flight on approach and I was listening in on my radio. I remember the pilot asking in a heavy German accent 'vhat are all zees fires ve are seeing?'
