San Francisco Supervisors to consider ban of certain plastics

The San Francisco Chronicle reports:

San Francisco supervisors are set to adopt the nation's first ban on some chemicals in plastic baby bottles, pacifiers and toys that may harm young children, a move that comes after a similar measure failed to pass in the California Legislature.

The measure is expected to be approved Tuesday, two weeks after supervisors voted unanimously in favor of the Child Safety Product Ordinance. It would take effect Dec. 1.

Under the proposed ordinance, no product that is intended for use by a child under 3 years of age could be manufactured, sold or distributed in San Francisco if it contains bisphenol A, or BPA, an ingredient in hard, clear polycarbonate plastic. Some forms of phthalate, a chemical that softens plastic, including polyvinyl chloride, or PVC, would also be banned.

We wonder if San Francisco has heard of the Commerce Cause in the U.S.Constitution.
