Too toxic to handle, yet approved for use in the environment?

You don't often come across scary stories like this one.  A chemical so toxic (Methyl Iodide), that scientists are wary of handling it, and is specifically used to induce cancer cells, is on the verge of being approved for use in soils, prior to planting of strawberries in California.  But wait, it's worse than that.  It was approved by George Bush's EPA in 2007, and the EPA standard of exposure is much higher (5x) than California's proposed regulation.  What's scary about that, is that 47 states have already licensed the usage of this chemical, and 12 states have allowed it to be used it at least once: Florida, North Carolina, South Carolina, Georgia, Alabama, Tennessee, Virginia, West Virginia, Michigan, Maine, New Jersey and Oregon.

Only licensed individuals are allowed to handle this stuff, but that's not the real world.  In the real world, anyone with two hands and a respirator will end up using it, using it in excess, and then illegally dumping the left over chemical.
