Industry and trade groups are suing to overturn San Francisco's newest ordinance aimed at protecting the city's toddlers from a suite of chemicals shown to cause cancer and hormone disruption in laboratory trials. The ban prohibits the sale and manufacture of toys and products intended for children under the age of 3, if they contain phthalates compounds used to soften plastics containing PVC and Bisphenol A.
