Transcript of Air Pollution
Respiratory effects from breathing sulfur dioxide.
High concentrations of sulfur dioxide showed decreased respiration.
Destruction of areas of the lung.
Herson Palma, Hunter Hayes, Jose Birriel, Victoria Peterson, and Sarah Severoni
Air Pollution in Beijing
Asthma & Air Pollution
The Coal & Power Plant Problem
Burning coal is very cheap and effective but dirty
releases sulfur dioxide --> sulfuric acid in the atmosphere
smoke stacks built to counteract direct disposition of sulfuric acid only spreads the problem
Effects of Acid Rain
Not many things can grow in acidic conditions
Low pH and high aluminum concentrations can damage or kill fish and other aquatic life
forests suffer from soil damage
Causes of Acid Rain
Burning coal. Oil & natural gas in power stations makes electricity
gives off sulfur gas
burning petrol & oil in car engines gives off nitrogen oxides as gases
these gases mix with water vapor/rainwater which fall back on earth as acid rain

Effects of Air Pollution
The Different Areas
Effects of Air Pollution on
Major Areas Affected:
Air pollution causes various diseases infecting the cardiovascular and respiratory organs
Depletes the Ozone Layer
Ilnesses causes people to miss school and work so people do not produce supplies and raise income
Damages trees, crops, wildlife, lakes, and other large bodies of water
Additionally, produces acid rain
Major causes of Air Pollution include:
Transportation (Cars, Airplanes, and etc.)
Burning Fossil Fuels (coal, petroleum)
Agricultural Activities (insecticides, pesticides, fertilizers)
Exhaust from Industries (CO, Hyrdrocarbons, and Organic Carbons)
Indoor Pollution (cleaning products)
Causes of Air Pollution
"Everyone knows that malaria is deadly. Or that access to clean water is a problem. And yet, in the next few decades, air pollution will kill far more people than both of those things combined, according to a new report" (Plumer).
"But the number of deaths caused by air pollution...is expected to skyrocket, killing more than 6 million people per year by mid-century" (Plumer).
"It is calculated that, each year, 470,000 people died as a result of ozone and 2.1 million deaths were linked to fine particulate matter (PM)" (Kinver).
"Air pollution increased respiratory and heart disease risks, with the young, elderly and infirm most vulnerable" (Kinver).
"Particulates from air pollution are implicated in causing or exacerbating respiratory and systemic cardiovascular diseases and are thought to be among the leading causes of morbidity and mortality" (Grunig, 25-35).

What is Asthma?
-Swelling or inflammation of air passages
-Trouble breathing, tightness of the chest, and wheezing
Asthma in Children
-It is proven that children living and/or going to school near roadways are more likely to develop asthma.
-Children have an increased chance of developing asthma after periods of time when pollutants are at high levels.
Adult On-Set Asthma
-"The evidence is consistent with the possibility that outdoor air pollution might play a role in causing asthma..." (Does Outdoor Air)
-Symptoms usually becomes worse as the patient ages due to "changes in muscles and stiffening of chest walls." (Adult-Onset Asthma Symptoms)
-It's less likely for a person to develop asthma after the age of 20.
Causes of health Risks
In a study conducted by Liqun Liu, it was found that the atmospheric particulate matter was the "leading cause of cardiovascular related emergency room visits"
Particulate matter can be man-made or natural
They have impacts on climate and precipitation that adversely effect human health
Elevated concentration levels of sub-micrometer particles were associated with increased cardiovascular morbidity.
Ultrafine particles showed delayed effects, while accumulation mode (100–1000 nm) particles showed immediate effects.
Using number or mass concentrations did not affect the particle effects.
Pre-Olympic games, air pollution at all time high
The Beijing Olympics created a decrease in air pollution.
Post-Olympic games, air pollution significantly and rapidly increased
Outcome: "Changes in air pollution levels during the Beijing Olympics were associated with changes in biomarkers of inflammation and thrombosis and measures of cardiovascular physiology in healthy young persons."
Though most causes of air pollution are anthropogenic, it effects, nature as well as animals around the globe.
The Human Health risks are critical and should not be taken lightly
So what will you do to stop it?
Acid Rain effects on Fish
Acid rain causes a lot of effects. Certain fish and animals, such as frogs, have a hard time adapting to and reproducing in an acidic environment. At pH 5, most fish eggs cannot hatch, and at lower pH levels some fish die. In fact, some acid lakes have no fish at all. Also, aluminum is released from soils into lakes and streams as acid rain flows through soils in a watershed. This aluminum is harmful to fish as well.
