This paper discusses mercury contamination, a serious environmental problem in aquatic ecosystems resulting in negative effects on birds, fish, mammals, and even humans. The writer explains how by testing the MeHg levels in various bird species that are known to be piscivorous, the MeHg pollution level in a local ecosystem can be assessed. This is key to keeping levels low in human populations as ecosystems with high MeHg levels should not be used for fishing. The paper concludes that various studies on bird populations show that both lethal and sublethal doses affect both behavior and productivity.

From the Paper:

"Mercury is a pervasive environmental pollutant that, in its gaseous elemental state, can be transported globally due to various characteristics that make it unreactive and stable, thus extended the lifetime of the elemental form. Mercury and most of its compounds are exceptionally toxic. Mercury is unique when compared to other trace metal elements found in the atmosphere as it is found almost entirely in its gaseous form (Hylander & Goodsite 2005). Mercury is deposited into the atmosphere due to both nature and human-generated sources. Most of the human-generated mercury comes from stationary combustion generally by coal-fired power plants and other municipal incinerators. Other sources include gold production, non-ferrous metal production, cement production, and other various sources."
