The Vermont House has given final approval to a bill to protect children from exposure to toxic chemicals. The House voted 120 to 22 Wednesday to advance a bill that would give the commissioner of health the power to require products containing certain chemicals to be labeled or to ban the chemicals. Those decisions would follow recommendations by a special advisory board and be reviewed by a legislative committee. The bill starts with a list of chemicals of concern that is borrowed from Washington state, which has a similar law. The main sponsor, Representative David Deen, said states are getting involved because the federal government has not done enough to protect people from exposure to toxic chemicals.
