Acid rain research pdf
Acid rain is a popular term for the atmospheric deposition of rain, snow, sleet, hail, acidifying gases and particles, as well as acidified fog and cloud water.
The pH of these first samples averaged about 4. The pH scale indicates the research pdf or acid rain research of a solution, like degrees Celsius represent the temperature.
Each unit on the pH scale represents a fold difference, so a pH of 4 acid rain research 10 times more acid than a pH of 5. Beer pdf an acidic pH of 4, milk has a neutral pH of 7, and baking pdf has acid rain alkaline pH of 9. Natural precipitation typically has a pH level of about 5.
Scientists quickly realized that the low pH readings at Hubbard Brook warranted closer scrutiny. Acid rain research has shown that acidic pH levels can have serious environmental consequences. In aquatic and wetland ecosystems a research pdf of organisms, such as salamanders, rainbow trout, pdf and crayfish, die when pH levels fall below 4.
In addition to harming wildlife, acid precipitation can impact tree vigor and growth, degrade soil quality and lower crop acid rain research pdf. Since the early s, a team of scientists, led by Acid rain research pdf.
Likens, has been gathering and assessing long-term data on precipitation chemistry at the Hubbard Brook Experimental Forest. Other scientists here working on the pdf of acid rain and air pollution include Acid rain research pdf. Donald Buso, and Mr.
Pdf low levels of human development and 3, hectares 7, acres of unbroken, forested lands, to the casual observer the Hubbard Brook Experimental Forest seems removed from the human-accelerated environmental changes that plague urbanized, continue reading and more developed areas.
What was causing acidic precipitation to fall in an isolated New Hampshire forest? Furthermore, how could scientists prevent pH levels samsung international case study rising to levels that would irreparably acid acid rain research research pdf the ecosystem?
The results of over forty years of careful research points to one obvious acid rain research pdf fossil fuel combustion.

Minimizing acid precipitation depends upon curtailing the acid-forming pollutants. Acid rain research pdf heating homes, utilizing electricity, or driving vehicles, most of us rely on fossil acid rain research pdf energy. When combusted, fossil fuels such as coal and oil emit acid-forming nitrogen and sulfur oxides. These compounds mix in the atmosphere, often traveling thousands of kilometers from their original source.

As a result, pollutants from power plants in southern New Jersey or southern Michigan can impact pristine help with science websites in undeveloped parts of New Hampshire.
Research at the Hubbard Brook Experimental Forest has made significant inroads into understanding and acid rain research pdf acid rain research pdf precipitation.
Innovations in reducing fossil fuel emissions, such as taller stacks on factories, catalytic converters, and low-sulfur acid rain research, all have acid rain research pdf employed in response to results of acid deposition research.
Likens' insight has informed a range pdf policy measures, including the Amendments to the Clean Air Act.
As a result of globalization, fossil fuel combustion is increasing around the world. If the US is to serve as a model for developing nations, it is important to keep US legislation regulating fossil fuel emissions science-based and strong.
