Add lead-bullet poisoning denialism to the crank magnetism list


This one was new to me:
Fresh off a wave of success in the state Capitol last year, animal welfare groups are taking aim at a new target this year: hunting with lead ammunition.

The Humane Society, Audubon California and Defenders of Wildlife are behind a major push to make California the first state to ban lead ammunition for all types of hunting....

....environmentalists say a statewide ban is needed because overwhelming scientific evidence shows condors, bald eagles and other birds are still dying from lead poisoning when they eat dead deer and other animals shot by hunters.... 
"These people want to ban hunting. Go to their cocktail parties and snuggle up to them, and that's what they'll tell you," said Don Saba, a member of the NRA board of directors.... 
Saba, a Tuscon, Ariz., resident who has a doctorate in toxicology from UC Berkeley, appeared last August at a state Fish and Game Commission meeting to question the science linking condor poisoning to bullets.... 
Scientists say it's clear bullets are to blame for the lead poisoning. They have published studies that match isotope ratios of lead in condors' feathers to isotope ratios in lead bullets.

Saba says that lead paint and other substances, like lead from batteries, also can have the same ratios, and that condors may be eating paint from old fire lookout towers, eating lead in dumps or finding it other ways. But researchers dispute those claims.

"What is lacking is any evidence -- and certainly no published evidence -- to substantiate their claims," said Don Smith, a professor of microbiology and toxicology at UC Santa Cruz.

Biologists track the birds with GPS and observe them closely, Smith noted. "They are not going to lots of fire towers to eat paint. They are not eating wheel weights off wheels," he said. "There isn't one shred of evidence they have to support any of that."

Evidence that they don't like, doesn't exist. One more for crank magnetism.
