Pollution is the process of making land, water, air or other parts of the environment dirty and not safe or suitable to use. This can be done. In this and the next study session we will look more closely at pollution. In this session you will learn about the different types and sources of pollution and the. Pollution is the introduction of contaminants into the natural environment that cause adverse Major forms of pollution include: Air pollution, light pollution, littering, noise The World's Most Polluted Places: The Top Ten of the Dirty Thirty (PDF), archived from the original (PDF) on , retrieved

Environmental Pollution is any discharge of material or energy into water, land, or air The following are the types of pollution perceived in our environment. Types of Pollution PPT, PDF: Definition of Pollution, Types, Air Pollution, Water Pollution, Noise Pollution, Land Pollution, Radio Active Pollution. Pollution is the introduction of harmful substances or products into the environment. • Main types of pollution. – Water Pollution. – Air Pollution. – Soil Pollution.
Other cities followed around the country until early in the 20th century, when the short lived Office of Air Pollution was created under the Department of the Interior. If we breathe the air which has pollutants then it will have bad effects on our health. Air pollution comes from both natural and human-made anthropogenic sources. This utility comes from the consumption of goods and services that create pollution. Major forms of pollution include: Respiration is a vital life process which needs air.

Many creatures which live in these water bodies are totally dependent on these water bodies. Causes of water pollution: Air pollution: Pollutants of air present in atmosphere are called as air pollution.
Respiration is a vital life process which needs air. If we breathe the air which has pollutants then it will have bad effects on our health. Air is comprised of below gases: Content of Gases Present in Air. Disruptions are caused when the above content of gases are disturbed. Causes of air pollution: Soil pollution: Soil pollution is nothing but stripping soil from its natural fertility by availing artificial chemicals like ripening agents, insecticides, and pesticides.
Normally, plants are dependent on nitrogenous compound for the purpose of their nutrition which is present in soil. Plants hold soil very firmly and when there is no growth of plants then it results in splitting of soil and at last causes to soil erosion. Thermal pollution: Thermal pollution is the increase in temperature because of high amount of release of heat energy by unnatural methods or techniques and natural disasters.
A little over half of the waste — million tons— was gathered in landfills. Only about 34 percent was recycled or composted. Organic material was the largest component of the garbage generated, the EPA said.
Paper and paperboard accounted for more than 26 percent; food was 15 percent and yard trimmings were 13 percent. Plastics comprised about 13 percent of the solid waste, while rubber, leather and textiles made up 9. Wood contributed to 6.
Commercial or industrial waste is a significant portion of solid waste. According to the University of Utah , industries use 4 million pounds of materials in order to provide the average American family with needed products for one year.
Much of it is classified as non-hazardous, such as construction material wood, concrete, bricks, glass, etc. Hazardous waste is any liquid, solid or sludge waste that contain properties that are dangerous of potentially harmful to human health or the environment.
Industries generate hazardous waste from mining, petroleum refining, pesticide manufacturing and other chemical production.
Households generate hazardous waste as well, including paints and solvents, motor oil, fluorescent lights, aerosol cans, and ammunition. Water pollution happens when chemicals or dangerous foreign substances are introduced to water, including chemicals, sewage, pesticides and fertilizers from agricultural runoff, or metals like lead or mercury.
According to the Environmental Protection Agency EPA , 44 percent of assessed stream miles, 64 percent of lakes and 30 percent of bay and estuarine areas are not clean enough for fishing and swimming. The EPA also states that the United State's most common contaminants are bacteria, mercury, phosphorus and nitrogen. These come from the most common sources of contaminates, that include agricultural runoff, air deposition, water diversions and channelization of streams.
Water pollution isn't just a problem for the United States. According to United Nations , million people do not have access to clean water and around 2. Adequate sanitation helps to keep sewage and other contaminants from entering the water supply.
According to National Oceanic and Atmospheric Administration NOAA , 80 percent of pollution in marine environment comes from the land through sources like runoff. Water pollution can also severely affect marine life. For example, sewage causes pathogens to grow, while organic and inorganic compounds in water can change the composition of the precious resource. According to the EPA, low levels of dissolved oxygen in the water are also considered a pollutant.
Dissolved oxygen is caused by the decomposition of organic materials, such as sewage introduced into the water. Warming water can also be harmful. The artificial warming of water is called thermal pollution. It can happen when a factory or power plant that is using water to cool its operations ends up discharging hot water.
This makes the water hold less oxygen, which can kill fish and wildlife.
