Health Effects of Air Pollution
In 2012, indoor air pollution was responsible for (MP3/A./2./a.)
4.3 million deaths worldwide, including 531,000 child deaths under the age of five from lower respiratory infections.
Preview: Today I am going to talk about...
A. What Air Pollution is, and the history behind it. B. The causes of air pollution: natural and man-made sources. C. Direct effects to human health caused by air pollution.
Review: Today I have informed you about...
A. What Air Pollution is, and the history behind it. B. The causes of air pollution: natural and man-made sources. C. Direct effects to human health caused by air pollution.
Conclusion:
After hearing the issues by this, it is important to keep the health of our world in mind as well.
Thesis:
Air pollution awareness is crucial to the health of current and future generations.
According to the Environmental Protection Agency, (MP1/B.)
In October 1948, Donora, PA, was engulfed in steel and zinc contaminants from nearby metal factories.
Conclude with Impact:
Now after learning about the damaging affects air pollution inflicts on humanity, it reveals the increasing relevance it has on our society and our world today.
Credibility:
The recent controversy over air pollution effects has broadened my interest in learning how it has affected current and past generations.
According to the World Health Organization, (MP3/A.)
air pollution is a major environment related health threat to children and a risk factor for acute and chronic respiratory disease.
These gaseous pollutants (MP1/A./1.)
and gaseous forms of metals are emitted from sources like fossil fuel fired plants, metal factories, industrial boilers, petroleum factories, and manufacturing facilities.
It is estimated that climate-related changes (MP3/B./1./b./a.)
and land-use practices are expected to increase the overall risk of wildfires in the coming decades, creating a growing need for information on the health impacts.
Wildfires, like the previously stated asthma sources,(MP3/B./1./b.)
are too, dangerous to humans after an elongated time of exposure which can cause lung and heart problems as well.
Examples of some are gases like (MP2/B./1.)
carbon monoxide, household products and chemicals, building materials like asbestos, formaldehyde, and even lead.
Within five days, (MP1/B./1.)
half of the towns 14,000 residents had severe respiratory or cardiovascular problems, killing 40 people.
As stated in the article, (MP3/A./1.)
in 2012, outdoor air pollution was responsible for 3 million deaths worldwide, in which 169,000 of them were children under the age of five.
The second type is (MP2/B.)
indoor air pollution, which involves exposures to particulates, carbon oxides, and many other pollutants carried by indoor air and dust.
A common pollutant (MP2/A./2.)
is ground-level ozone, a reactive form of oxygen and primary component of urban smog.
Living next to near road exposures(MP3/B./1./a.)
like roadways and railroads can in fact over a lengthened amount of time, cause lung and heart problems that can lead to a premature death.
Indoor air pollution has many determinants, (MP3/A./2.)
most commonly indoor cooking, and heating with biomass fuels or coal, producing high levels of indoor smoke containing a variety of health-damaging pollutants.
The first type is (MP2/A.)
outdoor air pollution, which involves exposures that take place outside of the built environment.
These are fine (MP2/A./1.)
particles produced by the burning of fossil fuels, noxious gases like sulfur dioxide, nitrogen oxides, carbon monoxide and chemical vapors.
Wildfires emit multiple types of (MP2/A./3.)
polluting gases and small particles, which pose serious health risks as well.
Open with Impact: Dr. Maria Neira, Director of Public Health with the World Health Organization
states in an article about ambient air pollution that "to date, air pollution both indoor [household] and outdoor [ambient], is the biggest environmental risk to health, carrying responsibility for about one in every nine deaths annually".
