! Holey crap, This will require some googling. What are safe levels ? Who says so ? Where did it come from ? And how soon can we get off this escalater to hell of capitalism ?
according to researchers, the contamination with arsenic comes from mining-related activities (Smedley P, Kinniburgh D; 2002). Safe levels are established by World Health Organization but, as far as I know, it's only for water contamination.

Hello,
according to researchers, the contamination with arsenic comes from mining-related activities (Smedley P, Kinniburgh D; 2002). Safe levels are established by World Health Organization but, as far as I know, it's only for water contamination.
You can see it by yourself at this link:
There's a pretty nice map :)
