is normally attributed to waste wood covered with old lead paint, but the Umass Amherst study suggests the metal is coming from the wood itself. This means that any wood burning could increase exposure in neighbourhoods and at home.

Henegan said: “The most logical answer is that it comes from uptake in the soil, probably riding along with the nutrients and water that trees need. Once in the tree, it deposits in the tree’s tissues and remains until that tree is burned.”

Lead pollution made it into the environment and will probably remain there for many generations.

I hope natural phenomenom and/or artificial capture methods will eventually make this negligible. So this does’nt become a perpetual pollution.
