What is air pollution? Air pollution is a complex mixture of many different substances and

the exact contents vary depending on what sources of pollution are nearby, your location, the time of year and even the weather. –Cancer research UK origination

Air pollution occurs when the air contains gases, dust, fumes or odour in harmful amounts. That is, amounts which could be harmful to the health or comfort of humans and animals or which could cause damage to plants and materials. –Victorian Government website

Introduction

Why is air pollution consider as a global environment problem? According to National Geographic1. Ozone layer 2. Global warming 3. Ice melting – according to the Trends of ecology and evolution

book 4. Water level increase 5. Climate change

Introduction

Causes

Indoor air pollution : According to Cancer Research UK which is a registered organization in UK

that there are mainly 2 important indoor air polluting causes which are: Second hand smoke.(caused by a person who breath co2 from someone

who smokes or any source of fire or co2 production inside the house) Radon .(Radon is a natural radioactive gas)So (whole presenting about indoor) u provide these numbers about second

hand smoke:Currently, millions of people in the UK are exposed to second-hand smoke

and 20 per cent of children report being exposed to second-hand smoke in their own homes.

Car exhaust •Acid Rain – Pollution from car exhaust contributes to the

formation of acid rain – acidic gases. •effect of global warming – Many of the gases from car

exhaust, such as carbon dioxide and nitrous oxide, are green house gasses. These gases trap heat within the Earth’s atmosphere and global climate change.

Causes

Passenger vehicles and heavy-duty trucks are the main sources of air pollution, which includes ozone, particulate matter, and other smog-forming emissions.

Air pollution by sulfur dioxide in Poland - impact on agriculture. After the Second World War there was a tremendous increase in SO2 emission in Polanddue to fast industrialization and the use of low quality coal as energy source. High levels of SO2 pollution have resulted in negative effects on natural and agro-

ecosystems. On the other hand SO2 has been beneficial as sulfur fertilizer for agro-ecosystems. Since SO2 emissions are expected to further decrease in Poland, sulfur content of

soils as well as plants needs to be monitored in order to guarantee optimized sulfur fertilization.

Factories in: China: Respiratory and heart diseases related to air pollution are the leading

cause of death in China. Various studies estimate pollution costs the Chinese economy about 7-10% of GDP each year. - WWF Global

- Mexico: In 1992, the United Nations described Mexico City’s air as the most

polluted on the planet because of the industrial growth. Six years later, that air earned Mexico the reputation of “the most dangerous city in the world for children. - IDRC

Effects of acid rains1. turn acidify water bodies2. affect the growth of plants3. increases the decay of buildings and monuments.4. Water species cannot survive in the water that has a higher

acidic level.

The Effect of Air Pollution on Lung Development from 10 to 18 Years of Age -By W. James Gauderman, Ph.D., Edward Avol, M.S

In this prospective study, we recruited 1759 children (average age, 10 years) from schools in 12 southern California communities and measured lung function annually for eight years. The rate of attrition was approximately 10 percent per year.

Yu estimates that the plan could reduce the fine particle load to 35 micrograms per cubic meter.

Solutions

BMW : If the engine's not running, it's not using any fuel. The Auto Start Stop function automatically switches off the

engine when the car is at a standstill and in neutral, then restarts it as soon as the driver presses the clutch pedal again. Fitted for example to all BMW 1 and 3 Series models with a four-cylinder engine and manual transmission, the Auto Start Stop function helps reduce both fuel consumption and emissions.

Solutions

To combat pollution in the United States, the Clean Air Act Amendments of 1970 gave the Environmental Protection Agency (EPA) the authority to establish and enforce air pollution standards and to set emission standards for new factories and extremely hazardous industrial pollutants. The states were required to meet "ambient air quality standards" by regulating the emissions of various pollutants from existing stationary sources, such as power plants and incinerators, in part by the installation of smokestack scrubbers, electrostatic precipitators, and other filters. Auto manufacturers were mandated to install exhaust controls or develop less polluting engines. The Clean Air Act, as amended in 1977, authorized the EPA to impose stricter pollution standards and higher penalties for failure to comply with air quality standards.

In 1990 when the act was reauthorized it required most cities to meet existing smog reduction regulations by the year 2005. The 1990 amendments also expanded the scope and strength of the regulations for controlling industrial pollution. The result has been limited progress in reducing the quantities of sulfur dioxide, carbon monoxide, nitrogen oxide, ozone, particulate matter, and lead in the air. The EPA also regulated hazardous air pollutants, which in 1992 included mercury, beryllium, asbestos, vinylchloride, benzene, radioactive substances, and inorganic arsenic.
