Acid Rain
 Websites presented in alphabetical order Clean Air Markets: Environmental Issues: Acid Rain 
 Introductory material about acid rain, "a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition." Includes a discussion of how acid rain is caused by pollutants in the environment, how acid rain is measured, and what can be done to reduce acid rain. Also includes experiments for students. In English and Spanish. From the U.S. Environmental Protection Agency (EPA). http://www.epa.gov/acidrain/ Topics: Environment, Pollutants & Toxic Substances Last updated Apr 25, 2006 The Environmental Literacy Council: Acid Rain
Overview of the phenomenon of acid rain, also known as acidic precipitation or acid deposition, which occurs "when sulfur dioxide and nitrogen oxides in the atmosphere [from pollution] react with oxygen in the air to form sulfuric acid (H2SO4) and nitric acid (HNO)." Includes discussion about the effect of acid rain on aquatic ecosystems, plants, buildings, and human health. Also includes links to related sites. http://www.enviroliteracy.org/article.php/2.html Topics: Pollutants & Toxic Substances, Water, Weather Last updated Apr 24, 2006 National Atmospheric Deposition Program (NADP)
The purpose of this national network is "to collect data on the chemistry of precipitation for monitoring of ... long-term trends." Weekly samples are analyzed to learn acid rain (also known as "atmospheric deposition") content. The site features links to data and reports. The NADP is located at the Illinois State Water Survey, and is a cooperative program of federal, state, and non-governmental groups. http://nadp.sws.uiuc.edu Topics: Pollutants & Toxic Substances, Water, Weather Last updated Apr 24, 2006 |
