Level drop
The EPA last reduced the recommended limit in 2001. Until then, it had been set at 50 ppb. It was lowered to 10 ppb after concerns about cancer risks.
"Since then, research at lower and lower exposure levels have been performed," says Clark Lantz at the University of Arizona in Tucson.
The EPA is convening an advisory panel to evaluate the human and animal data on arsenic risk for non-cancer diseases to determine whether the 10 ppb limit is adequate to protect human health, says Aaron Barchowsky at the University of Pittsburgh in Pennsylvania.
"An important question is whether reducing the current limit further would be an improvement for public health that is economically sustainable," he says, adding that reducing the limit to 2 ppb could cost trillions of dollars to enforce in the US.
Thank you for recording it again, koe_o_kasu. I like you voice and speed.
