Researchers discover way to transport environmental arsenic to plant leaves in new clean-up strategy

...alled "Green Revolution" of the '60s and '70s, the cultivation of rice in flooded fields became pervasive, and workers dug open wells all over India through soil and rocks with naturally occurring arsenic. The result was widespread arsenic pollution from contaminated water. The problem is thus extremely widespre...
