Toxic mercury concentrations found in California's coastal fog — and the area's mountain lions

By

Fog along the coast of the Santa Cruz Mountains in California contains significant levels of toxic mercury — and it's already hurting wildlife in the area. 

The findings come from a recent study published in the journal Nature, and conducted by environmental toxicologist Peter Weiss-Penzias and a team of researchers at University of California, Santa Cruz. Most significantly, the team observed that mercury concentrations in mountain lions (also known as pumas, cougars, and panthers) in the fog area was three times higher than that of mountain lions outside the fog area.
