It refers to the contamination of the atmosphere by harmful chemicals or biological materials. Read about how air pollution can affect your health.
Excellent resource center to find tips and other information on how to keep the air cleaner. Acid rain is problematic due to acidification of soil, rivers, and lakes beyond the tolerance range of plants and animals. Read about ozone and ozone layer depletion in relation to air pollution.
These acids commonly result from sulfur dioxide and nitrogen oxides reacting with moisture and other substances in the atmosphere. An overview of how human activity affects air pollution. The "rain" then comes in two forms: See References 5 Buildings Limestone and marble construction materials are especially damaged by acid rain.
VOCs are produced by various sources, such as paint, cleaning products and refrigerants. A look at volcanic gases and the effects on the Earth. Other natural causes of air pollution are natural sources of particulate matters like volcanoes and dust storms, volatile organic compounds, pollen, forest fires, oceans, and forest fires.
See References 2 Forests Direct contact with acid rain can weaken trees and destroy their leaves. Acid rain can also erode man-made structures. These pollutants may even infiltrate indoor spaces causing problems ranging from asthma to premature death.
The VOCs prevent the breakdown of ozone, allowing it to gather near the surface of the Earth, where even more nitric oxides are produced by vehicle and industry emissions, creating the dense smog seen in large cities such as Los Angeles and Beijing.
Respiratory systems can be irritated, reducing overall lung function and triggering asthma attacks. Gas-powered garden equipment should be avoided as well as the burning of trash, leaves, and other materials.
Highlights the main natural causes of air pollution. The report focuses on how transportation can affect air quality. Environmental Protection Agency reports that between andthe national average for sulfur dioxide in the air decreased by 76 percent, and nitrogen dioxide decreased by 48 percent.
The site is dedicated to encouraging people to do small things to clean the air collectively. Provides information on the index for daily reporting of air quality. Good place to find air quality data for various states. Natural Causes of Air Pollution Other than human actions, air pollution is also caused by natural events.
Excellent overview of the health effects of air pollution. Provides information on the IAQ. What Can You Do? Provides information on the various health effects of air pollution.
Highlights some of the common health problems caused by air pollution.
A study on the air pollution brought about by the eruption of this volcano. Help to stop air pollution with these tips. Smog Hazards The presence of ozone in the form of smog can have several negative health effects.
Nitrogen dioxide interacts with sunlight to create nitrogen oxide and a free oxygen molecule. Offers information on air quality indicators in Canada.
Biological decay and volcanoes release natural sulfur dioxides and nitrogen oxides, affecting air quality in negative ways. The addition of VOCs interrupts the cycle, however.
Keeping the Air Clean: This interaction produces ozone, which typically turns back into nitrogen dioxide, and the cycle repeats. These components interact with oxygen and water vapor in the air, creating compounds that are acidified close to 5 on the pH scale, well under the neutral 7 pH.
To reduce the problems of air pollution, people should be more aware of their actions in these areas. This is especially true in high altitude forests where the trees are frequently immersed in an acid cloud. Explains how forest fires can affect air quality.
Discusses all about indoor air pollution and what you can do to reduce it.
Follow these steps to keep the air cleaner.Acid rain describes sulfuric and nitric acids deposited from the atmosphere. Often associated with precipitation, the term also applies to dry acidic materials.
These acids commonly result from. Overview of the Clean Air Act and Air Pollution Progress Cleaning the Air: Actions to implement the Clean Air Act have achieved dramatic reductions in air pollution, preventing hundreds of thousands of cases of serious health effects each year.
AIR POLLUTION Overview and Issues on Emissions Allowance Trading Programs Statement of Peter F. Guerrero, Director, other types of air pollutants.
In one example of a trading program, the issue of acid rain by reducing SO 2 emissions, a major cause of the problem. Specifically, title IV of the Clean Air Act allows electric utilities. Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole.
The Clean Air Act authorizes the U.S. Environmental Protection Agency. Acid rain describes any form of precipitation with high levels of nitric and sulfuric acids. It can also occur in the form of snow, fog, and tiny bits of dry material that settle to Earth.
Smog and acid rain are produced through similar sources, primarily vehicle and industry emissions. Though both result from human-caused air pollutants, there are chemical distinctions between the two. Though there are regulations in effect to reduce both types of pollution, they remain a threat to both human health and the environment.Download
