quality that warrants continued attention is acid deposition, commonly called acid rain. Through the emission and deposition of sulfur dioxide and nitrogen oxides associated with the burning of fossil fuels, many lakes and streams across the region have become too acidic to continue to support aquatic life as in the past.
CHAPTER 13. ACID RAIN. Acid rain was discovered in the 19th century by Robert Angus. Smith, a pharmacist from Manchester (England), who measured high levels of acidity in rain falling over industrial regions of. England and contrasted them to the much lower levels he observed in less polluted areas near the coast.
Background. An acid is a chemical that has extra hydrogen particles in it. When certain gases mix together with water in our atmosphere, it can create acid rain. Creating pollution can sometimes cause more acid rain to be produced. Is there acid rain all the time? Is it always the same? ? Questions. Does precipitation in
Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the
The author wishes to thank the Executive Office of Environmental Affairs for its vision in assembling the Massachusetts Acid Rain Research Program and including as part of that program support for this effort to compile the results of the program into a booklet for public dissemination. Special thanks to Assistant Secretary for
Acid Rain. —why it is a concern. Issued March 2004. EPA 089/04: This document replaces the EPA Information Sheet No. 22, 'Acid Rain' (January. 2001). It explains what acid rain is and the adverse affects it has upon humans and the environment, and provides information on how acid rain can be reduced. Introduction.
National Acid Precipitation Assessment Program. (NAPAP), to determine the causes and effects of acid rain and to make recommendations concerning its control. NAPAP issued an Interim Assessment in late 1987 and will publish the Final Assessment and State of the Science documents in 1990. At the beginning of this

By reducing the emission of the precursors of acid rain and to some extent by liming, the problem of acidification of terrestrial and aquatic ecosystem has been reduced during last two decades.

The National Acid Precipitation. Assessment Program (NAPAP), mandated by Congress, begins study on acid rain.
streams, lakes and ponds - abound in Newfoundland and Labrador. Some of them are more seriously affected than others by acid rain. The ability of a body of water to resist the impact of acid rain is termed the buffering capacity of the water. Some fresh- water systems are very well buffered and are completely resistant to.
