“Lead is a toxin that is bad for human health and the environment, and lead ammunition exposes humans and other animals to this life-threatening poison,” Assemblyman Anthony Rendon from the Southern California city of South Gate, who sponsored the bill, said in a statement. “There is simply no reason to continue using lead ammunition in hunting, and today’s vote gives me great hope that we can eradicate this highly toxic element from our environment.”

Foes of lead ammunition note that the Fish and Wildlife Service already requires nonlead steel shot for hunting geese and ducks. In 2009, the National Park Service announced the goal of eliminating lead ammunition.

But hunting advocates argue that the elemental lead used in bullets is far less soluble and less toxic than the industrial lead used in manufacturing. They point to a study conducted on the California condor showing that the birds continue to register the same blood-lead levels even after a five-year ban on ammunition in their habitat.

“Those attempting to impede hunters’ rights through the prohibition of traditional ammunition consisting of lead components have used the California condor as a propaganda tool to advance their campaign,” said the pro-hunting website Hunt for Truth.

The lead ban would take effect in 2019, which undercuts the argument that ammunition presents a pressing health threat, said Tim Rosales, spokesman for the union group Californians for Conservation.

“If this is such an urgent threat to human and animal health, there’s no way they would push it back to 2019,” Mr. Rosales said. “The agenda of these animal-rights groups is to ban hunting and fishing. That’s the real goal.”

The rash of gun-control bills coasted through the state Legislature, where Democrats hold supermajorities in both houses. At the same time, some rural Democrats voted against the bills, illustrating the state’s rural-urban divide.

California may be bluer than Colorado, but gun rights advocates say signing the gun bills could trigger a similar uprising. Two Democratic state senators were recalled by Colorado voters Sept. 10 in reaction to their support for three gun-control bills.

“If [Gov. Brown] does sign them, I think that we’re going to see an outcry brewing,” Mr. Jones said. “These are hard-working families, a lot of whom happen to be union, and they’re hunters, they’re sportsmen, they’re honest, law-abiding gun owners who feel like their Second Amendment rights are being attacked. And they don’t like it.”
