For an article titled "how coal kills", I must say I am not much more wiser from reading it. Is it only from specific impurities which are themselves toxic elements, or does the carbon play a role? Is it the size of the particles in coal smoke/ash, or is it the molecules? Do they interact to form something deadlier than the sum of the parts?
I know coal kill. What would be interesting to know is how.
