[ RadSafe ] coal ash toxicity contribution from uranyl

[Bjorn Cedervall]

I question whether anything meaningful biological conclusions can be drawn from this paper.

Fly ash - isn't that a mix with elements from more than half of the periodic system?

To go from there and directly to specific mechanisms relating to DNA damage (what kind of damage?) seems like a speculation.

 

My personal comment only,
