Visual pollution, which can refer to the presence of overhead power lines, motorway billboards, scarred landforms (as from strip mining), open storage of trash, municipal solid waste or space debris.Thermal pollution, is a temperature change in natural water bodies caused by human influence, such as use of water as coolant in a power plant.
(See alpha emitters and actinides in the environment.) Radioactive contamination, resulting from 20th century activities in atomic physics, such as nuclear power generation and nuclear weapons research, manufacture and deployment.Among the most significant soil contaminants are hydrocarbons, heavy metals, MTBE, herbicides, pesticides and chlorinated hydrocarbons. Soil contamination occurs when chemicals are released by spill or underground leakage.Plastic pollution: involves the accumulation of plastic products and microplastics in the environment that adversely affects wildlife, wildlife habitat, or humans.Noise pollution: which encompasses roadway noise, aircraft noise, industrial noise as well as high-intensity sonar.Littering: the criminal throwing of inappropriate man-made objects, unremoved, onto public and private properties.Light pollution: includes light trespass, over-illumination and astronomical interference.It's still unknown whether or not those types of radiation have any effects on human health, though. Electromagnetic pollution: the overabundance of electromagnetic radiation in their non-ionizing form, like radio waves, etc, that people are constantly exposed at, especially in large cities.
Particulate matter, or fine dust is characterized by their micrometre size PM 10 to PM 2.5. Photochemical ozone and smog are created as nitrogen oxides and hydrocarbons react to sunlight. Common gaseous pollutants include carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs) and nitrogen oxides produced by industry and motor vehicles. Air pollution: the release of chemicals and particulates into the atmosphere.The major forms of pollution are listed below along with the particular contaminant relevant to each of them:
