Water pollutionby the discharge of wastewater from commercial and industrial waste intentionally or through spills into surface waters ; discharges of untreated domestic sewageand chemical contaminants, such as chlorinefrom treated sewage; release of waste and contaminants into surface runoff flowing to surface waters including urban runoff and agricultural runoff, which may contain chemical fertilizers and pesticides ; also including human feces from open defecation - still a major problem in many developing countries ; groundwater pollution from waste disposal and leaching into the ground, including from pit latrines and septic tanks ; eutrophication and littering.
First assessment report[ edit ] Main article: For example, hurricanes often involve water contamination from sewage, and petrochemical spills from ruptured boats or automobiles. Ordinary municipal landfills are the source of many chemical substances entering the soil environment and often groundwateremanating from the wide variety of refuse accepted, especially substances illegally discarded there, or from pre landfills that may have been subject to little control in the U.

It was the industrial revolution that gave birth to environmental pollution as we know it today. The major forms of pollution are listed below along with the particular contaminant relevant to each of them: Radioactive contaminationresulting from 20th century activities in atomic physicssuch as nuclear power generation and nuclear weapons research, manufacture and deployment.

It is split into four parts: Soil can become infertile and unsuitable for plants.Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light.
Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring mint-body.comion is often classed as point source or nonpoint source pollution.
