Fish
Countless types of fish, including some of our most popular sport fish, are affected by mercury contamination. Rainbow trout in mercury contaminated environments suffer from growth inhibition and high mortality of embryos and larvae. Yellow perch and northern pike with high mercury concentrations have impaired kidney function and endocrine disruption.

Loons
Contaminated loons hatch 50 percent less young, incubate eggs for significantly less time and produce lighter eggs. In chicks, high mercury concentrations affect brooding and feeding.

Frogs
Scientists believe mercury is a factor in the increasing incidence of limb deformities among species such as bullfrogs and northern leopard frogs, which spend most of their lives in water. High mercury concentrations in frogs have also been shown to cause high embryo-larval mortality.

Humans
Mercury exposure in pregnant women resulted in memory, attention and language development problems in their young children. Both men and women have suffered from infertility as a result of high blood mercury levels.

Florida Panther
Research has indicated the mercury contamination may be a contributing factor in the decline of the Florida panther.
