Increasing nitrogen emissions from motor vehicles, energy production, and agriculture are being deposited in lakes throughout the world, directly affecting lake biology and associated food webs. Alpine lake ecosystems are especially vulnerable to this deposition. USGS scientist Jill Baron, co-author of two new studies on how increased nitrogen pollution can affect lake ecosystems and water quality, discusses the issue.

The United States is using less water than during the peak years of 1975 and 1980, according to USGS water use estimates for 2005.

Mercury contamination was detected in every fish sampled in 291 streams across the country. About a quarter of these fish were found to contain mercury at levels exceeding the criterion for the protection of people who consume average amounts of fish, established by the U.S. Environmental Protection Agency. We talked to Lia Chasar, lead ecologist on the USGS study.
