Two stories today focus on two different states’ efforts to get lead out of the environment.
An article in the Portland (Maine) Herald Press literally goes behind the scenes of the recent legislative ban on lead fishing gear in Maine, which was passed earlier this year, but won’t totally ban the lead gear until 2017. It goes into the lab of Mark Pokras, a Tufts University professor of wildlife health, who played a role in encouraging that legislation. Pokras has been studying lead poisoning in loons for over 20 years.
Pokras says that lead poisoning is responsible for the deaths of over a third of the loons that find their way to his lab in Massachusetts.
In Minnesota, studies show that a bad shot with a lead bullet (such as one that hits a hip bone), can cause lead to splinter throughout a white tailed deer’s flesh to the extent that it would be difficult, or impossible, to remove all of it. For the sake of public health, and also for the sake of the state’s bald eagles, the Minnesota Department of Natural Resources encourages deer hunters to voluntarily use copper bullets.
The article details some of the differences between hunting with copper and lead bullets, which implies that a different technique may be more effective when using copper bullets.
