I wonder if this is the dirty bomb Natural News has been predicting for awhile. This seems in some ways almost as bad as a nuclear bomb. And all they have to say is that it was an accidental derailment. This was done on purpose.
In a way its way worse. Nuclear stuff over time breaks into smaller pieces becoming less and less harmful . With those dioxins its opposite , similar crap sticks together / accumulates ,becoming more and more toxic.And they can break apart again (like if you burn them),go airborn,into groundwater etc.
"Oh, and it bioaccumulates. So fishing/hunting/animal-agriculture over a large area will become nonfunctional. And then the impacts on wildlife."
So it kinda is like chernobyl if they want to get rid off it then everything alive or dead that is contaminated with it must be disposed in some similar place where they dump nuclear waste otherwise it keeps on circling from one lifeform to another,causing cancer etc. So that would mean hunting down and killing all wildlife ,pets etc ... And since it accumulates also on humans...
How to clean it from soil and groundwater ? Atleast radioactive crap you can detect easily with instruments over great distances but this stuff is a silent killer.
