Transcript of GIS Presentation
We will be covering the issue of air pollution in the Southern California area.
We will discuss the health complications it causes among the younger population, such as asthma.
We will depicted these issues through maps using data gathered:
Graduated Color Maps

Asthma is a chronic disease that affects your airways
The inside walls of your airways become sore and swollen.
Children with asthma may experience wheezing, coughing, chest tightness, and trouble breathing, especially early in the morning or at night.

What we can do to Help with the Pollution Problem
Even though the Air Pollution epidemic is a huge task to take on and a difficult problem to fix. We can still do our part to not further contribute to the issue.
These are some suggestions:
- Combine trips, walk, bike, carpool or vanpool, and use buses, subways or other alternatives to driving.
Use less electricity
- Turn out the lights and use energy efficient appliances.
Don’t burn wood or trash
- Burning firewood and trash are among the largest sources of particles in many parts of the country.
Send a message to Congress
- Urge them to support cleaner, healthier air and oppose measures to block or delay the cleanup of air pollution.
Ask the EPA to set tighter standards
- for such issues as gasoline and tailpipe pollution standards for cars, trucks and SUVs
- Participate in your community’s review of its air pollution plans and support state and local efforts to clean up air pollution

"What's in the air"
HEA 497-Professor Morales
We would like to show the spatial relationship between air pollution and asthma among the school age population.
What is Air Pollution?
According to the World Health Organization (WHO)
Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere.
Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide.
Outdoor and indoor air pollution cause respiratory and other diseases, which can be fatal.
There are two types of air pollution dominate in the U.S.
This is one of the most widespread pollutant
Ozone or O3 is an invisible gas molecule composed of three oxygen atoms
In the presentence of the right ingredients: NOx, VOCs, CO & sunlight ; they react to form SMOG
Particle pollution refers to a mix of very tiny solid and liquid particles that are in the air we breathe.
Such as the dirty, smoky part of that stream of exhaust from vehicles.
Particle pollution can increase the risk of heart disease, lung cancer and asthma attacks and can interfere with the growth and work of the lungs.
Important Facts to Consider about Air Pollution
3 million people die each year of air pollution effects, 700 thousand are within the U.S, and 5,OOO Southern Californians die prematurely
Death ratios between air pollution and breast/prostate cancer are equal.
Approximately 4 trillion tons of carbon is accumulated in the air each year.
46% percent of Americans reside in counties with unhealthy air of either ozone or particle pollution.
Air Quality in California
Based on The American Lung Association “State of the Air 2013” report, shows the air quality nationwide.
Los Angeles once again tops the list for the worst ozone pollution in the country for the 13th time in the 14 years the report has been issued.
Californians, in general, tend to inhale the dirtiest air:
Top 10 Most Ozone-Polluted Cities
Los Angeles-Long Beach-Riverside, Calif.
Sacramento-Arden-Arcade-Yuba City, Calif.-Nev.
Dallas-Fort Worth, Texas
Washington-Baltimore-Northern Virginia, District of Columbia-Md.-Va.-W.Va.
El Centro, Calif.
How the Bad Air affects You
Year Round Exposure could possibly cause serious threats, such as:
early death (both short-term and long-term exposure)
cardiovascular harm (e.g. heart attacks, strokes, heart disease, congestive heart failure)
Likely to cause respiratory harm (e.g. worsened asthma, worsened COPD, inflammation)
May cause cancer
May cause reproductive and developmental harm
How it affects Children
Children face special risks from air pollution because their lungs are growing and they are very active.
80% of their tiny air sacs, called alveoli, develop after birth. This is where the life-sustaining transfer of oxygen to the blood takes place.
Their body’s defenses that helps fight off infections are still developing in their young bodies, this is why children have more respiratory infections than adults.
Chronic Diseases that affect CA Children
Low birth weight and/or premature birth for children in utero
Under developed lungs and lowered functioning
Chronic Obstructive Pulmonary Disease (COPD)
This is the leading chronic disease in children
Nearly 9 million children have Asthma in the U.S.
In LA county 1,173,000 children have been diagnosed with asthma.
63,000 students in Los Angeles Unified School District (LAUSD) have asthma.
The highest increases in asthma are found in urban areas and among African-Americans and Latinos.
The asthma hospitalization rates for African-American children in Southland counties are two to four times higher than for other ethnic or racial groups.
