AirPollutionThe moment you step out of the house and are on the road you can actually see the air getting polluted; a cloud of smoke from the exhaust of a bus, car, or a scooter; smoke billowing from a factory chimney, flyash generated by thermal power plants, and speeding cars causing dust to rise from the roads. Natural phenomena such as the eruption of a volcano and even someone smoking a cigarette can also cause air pollution. |
Water Pollution
The important sources of water pollution are domestic wastes, industrial effluents and agricultural wastes. Other sources include oil spills, atmospheric deposition, marine dumping, radioactive waste, global warming and eutrophication. Among these, domestic waste (domestic sewage) and industrial waste are the most important sources contributing to water pollution.

Land Pollution
Land pollution basically is about contaminating the land surface of the Earth through dumping urban waste matter indiscriminately, dumping of industrial waste, mineral exploitation, and misusing the soil by harmful agricultural practices. Land pollution includes visible litter and waste along with the soil itself being polluted. The soil gets polluted by the chemicals in pesticides and herbicides used for agricultural purposes along with waste matter being littered in urban areas such as roads, parks, and streets.

Noise Pollution
Noise pollution is a type of energy pollution in which distracting, irritating, or damaging sounds are freely audible. As with other forms of energy pollution (such as heat and light pollution), noise pollution contaminants are not physical particles, but rather waves that interfere with naturally-occurring waves of a similar type in the same environment. Thus, the definition of noise pollution is open to debate, and there is no clear border as to which sounds may constitute noise pollution. In the most narrow sense, sounds are considered noise pollution if they adversely affect wildlife, human activity, or are capable of damaging physical structures on a regular, repeating basis. In the broadest sense of the term, a sound may be considered noise pollution if it disturbs any natural process or causes human harm, even if the sound does not occur on a regular basis |
RadioActive Pollution
Certain atoms are radioactive, meaning they emit radioactivity during spontaneous transformation from an unstable isotope to a more stable one. Radioactive pollution results from contamination of the environment with such substances, which may represent a significant health risk to humans and other organisms. Radioactive pollution differs from conventional pollution in that it cannot be detoxified. Instead, radioactive materials must be isolated from the environment until their radiation level has decreased to a safe level, a process which requires thousands of years for some materials.

Thermal Pollution
Waste Heat - A pollutant as dangerous to waters as more tangible of forms of waste Human activity can change normal temperature: By altering environment of watercourse: Road building , logging, poundments, diverting flows for irrigation Adding or removing heat. On national scale, industrial cooling waters is a first-order source of heat. Electro power generation uses 80% of cooling waters. Best single index of thermal pollution lies in projecting future electric power generation. Past experience has indicated that thermal pollution has not multiplied as fast as power generation because of improvements in thermal plant efficiency and developement of hydropower. Nulear plants - waste even higher proportion of heat than fossil-fuel plants. Heat rejection is expected to increase nine fold by the year 2000. Problem is one of managing tremendous amounts of waste heat in a manner that will maintain or enhance, physical, chemical and biological nature of our water resources. |
Chemical Pollution
Chemical pollution is when certain compounds are left or disposed of in the environment. The chemicals disrupt the processes of the ecosystem. This cause the biological elements to be killed or harmed. Some types of Chemical Pollution? one example is of us humans carrying toxic waste or chemicals across the ocean. This tends to result in a leak. This is how the chemicals get released. Antoher way is purposely. We constantly are dumping things we dont want in the ocean in forests and in deserts. This cause a chemical or a toxic substance. Causes are simply people. These noxious liquids are acetone cyanohydrin, carbon disulphide, cresols, naphthalene and tetraethyl lead. acrylonitrile, carbon tetrachloride, ethylene dichloride and phenol.benzene, styrene, toluene and xylene. acetone, phosphoric acid and tallow. There may be copied forms in the above due to the fact that i copied and pasted form a report i did.
