Transcript of Ph Levels in The Great Lakes

Thank You!
PH Levels
Ph Levels are what determines the acidity of a substance such as water or vinegar. It also helps determine if a substance is a base or an acid.
Acid Rain is the wet or dry deposition of acidic substances created on the Earths surface. The ongoing use of factories and vehicles has resulted in the increase of acidic toxins released into the atmosphere. These toxins come back down to earth as Acid Rain affecting forests, lakes and human health.
The majority of acid rain comes from fossil fuels such as oil, coal and natural gases burned in industry. When put in to the atmosphere they are mixed moisture and interact with sunlight and create sulfuric acid and nitric acid that fall back down to Earths surface.
How the Enviroment effects the Great Lakes
Most natural waters in Northern America have an average Ph level of 6.5 or 8.5. Rain quite often has a Ph level of 5.0 or 6.0. Acid Rain has an average Ph level of 4.3. Lakes that get Acid Rain can have down to a Ph level of 4. The Great Lakes are protected from Acid Rain by Limestone Bedrock which acts as a buffer to neutralize Acid Rain. When our Great Lakes Ph levels are messed around by Acid Rain the wildlife in the Lakes suffer greatly from the increased and or decreased acidity in the Great Lakes water
Wildlife in the Great Lakes
The constant change of Ph levels in the Great Lakes can have a great impact on the wildlife in the Great Lakes. Scientists are almost certain that the change of Ph levels in the Great Lakes effect our native wildlife in the Lakes. Seeing as they have taken accustom to they're natural habitat. Certain native animals will take the effect of the difference of acidity harder then others which may indeed kill of certain species of animals in the Great Lakes. Which can lead to a chain reaction destroying the whole eco system of our Great Lakes.
