Very interesting - thank you!
It's apparently coal burning chimneys that were of concern there. "In effect until 1964" - which is even more interesting. My understanding is that in 1952, the effects of privation from WWII were still acutely felt. I wonder if the rising economy didn't make better fuel more affordable.
