Environmentalists are pushing legislation to ban lead ammunition in California to prevent toxins from poisoning scavengers that eat animal remains left by hunters.

Final language of the bill was introduced Monday by Assembly Member Anthony Rendon, D-Lakewood, who said the legislation would remove a lingering source of pollution from the environment. It was sponsored by three major environmental groups — Defenders of Wildlife, Audubon California, and the Humane Society of the United States.

“There really is no question that lead ammo is a threat,” said Kim Delfino of Defenders of Wildlife. “To pass a bill in California would set the stage for this happening throughout the country, the way low-emissions vehicle standards changed the market nationwide.”
