[QUOTE="Shootin4fun, post: 849156, member: 28741"] And they further state that the current ban which hunters have been 99.9% compliant has not had a measurable effect yet that if they get rid of all lead ammo the problem will be solved. I don't quite get it. Following this section they talk about all animals in the food chain being affected by lead, inferring that the next logical move would be a complete ban of hunting with bullets containing lead. [FONT=serif][SIZE=3]These results are especially pertinent given recent regulatory[/SIZE][/FONT] [FONT=serif][SIZE=3]efforts in California to mitigate the lead exposure hazard to[/SIZE][/FONT] [FONT=serif][SIZE=3]California condors by partial bans of lead ammunition use in[/SIZE][/FONT] [FONT=serif][SIZE=3]condor habitat (39, 40). Although these regulations have been[/SIZE][/FONT] [FONT=serif][SIZE=3]in place for only a few years, we looked for evidence that they[/SIZE][/FONT] [FONT=serif][SIZE=3]had impacted the prevalence of lead poisoning in California[/SIZE][/FONT] [FONT=serif][SIZE=3]condors.
