Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. It is the result of long-term destruction from human. The process is known as leaching.

Controlled burning stimulates the germination of some desirable forest trees, thus renewing the forest. Fumes from paint , hair spray , varnish , aerosol sprays and other solvents. These can be substantial; emissions from these sources was estimated to account for almost half of pollution from volatile organic compounds in the Los Angeles basin in the s.

Methane is highly flammable and may form explosive mixtures with air. Methane is also an asphyxiant and may displace oxygen in an enclosed space. Asphyxia or suffocation may result if the oxygen concentration is reduced to below Fertilized farmland may be a major source of nitrogen oxides.

Dust from natural sources, usually large areas of land with little or no vegetation Methane , emitted by the digestion of food by animals , for example cattle Radon gas from radioactive decay within the Earth's crust. Radon is a colorless, odorless, naturally occurring, radioactive noble gas that is formed from the decay of radium. It is considered to be a health hazard.

Radon gas from natural sources can accumulate in buildings, especially in confined areas such as the basement and it is the second most frequent cause of lung cancer, after cigarette smoking.

Smoke and carbon monoxide from wildfires. These VOCs react with primary anthropogenic pollutants—specifically, NOx, SO2, and anthropogenic organic carbon compounds — to produce a seasonal haze of secondary pollutants. The VOC production from these species result in ozone levels up to eight times higher than the low-impact tree species. These factors are usually expressed as the weight of pollutant divided by a unit weight, volume, distance, or duration of the activity emitting the pollutant e.

Such factors facilitate estimation of emissions from various sources of air pollution. In most cases, these factors are simply averages of all available data of acceptable quality, and are generally assumed to be representative of long-term averages. There are 12 compounds in the list of persistent organic pollutants. Dioxins and furans are two of them and intentionally created by combustion of organics, like open burning of plastics. These compounds are also endocrine disruptors and can mutate the human genes.

The United States Environmental Protection Agency has published a compilation of air pollutant emission factors for a wide range of industrial sources. Air pollution exposure can be expressed for an individual, for certain groups e. For example, one may want to calculate the exposure to a hazardous air pollutant for a geographic area, which includes the various microenvironments and age groups.

This can be calculated [35] as an inhalation exposure. This would account for daily exposure in various settings e. The exposure needs to include different age and other demographic groups, especially infants, children, pregnant women and other sensitive subpopulations. The exposure to an air pollutant must integrate the concentrations of the air pollutant with respect to the time spent in each setting and the respective inhalation rates for each subgroup for each specific time that the subgroup is in the setting and engaged in particular activities playing, cooking, reading, working, spending time in traffic, etc.

For example, a small child's inhalation rate will be less than that of an adult. A child engaged in vigorous exercise will have a higher respiration rate than the same child in a sedentary activity. The daily exposure, then, needs to reflect the time spent in each micro-environmental setting and the type of activities in these settings.

A lack of ventilation indoors concentrates air pollution where people often spend the majority of their time. Radon Rn gas, a carcinogen , is exuded from the Earth in certain locations and trapped inside houses. Building materials including carpeting and plywood emit formaldehyde H2CO gas.

Sufferers have severe dyspnea shortness of breath and are at an increased risk regarding several different types of lung cancer. As clear explanations are not always stressed in non-technical literature, care should be taken to distinguish between several forms of relevant diseases.

According to the World Health Organization WHO , these may defined as; asbestosis , lung cancer, and Peritoneal Mesothelioma generally a very rare form of cancer, when more widespread it is almost always associated with prolonged exposure to asbestos. Biological sources of air pollution are also found indoors, as gases and airborne particulates. Pets produce dander, people produce dust from minute skin flakes and decomposed hair, dust mites in bedding, carpeting and furniture produce enzymes and micrometre-sized fecal droppings, inhabitants emit methane, mold forms on walls and generates mycotoxins and spores, air conditioning systems can incubate Legionnaires' disease and mold, and houseplants , soil and surrounding gardens can produce pollen , dust, and mold.

Indoors, the lack of air circulation allows these airborne pollutants to accumulate more than they would otherwise occur in nature. Health effects See also: Neuroplastic effects of pollution In , air pollution caused premature deaths on average of 1 year in Europe, and was a significant risk factor for a number of pollution-related diseases , including respiratory infections , heart disease , COPD , stroke and lung cancer.

These effects can result in increased medication use, increased doctor or emergency department visits, more hospital admissions and premature death. The human health effects of poor air quality are far reaching, but principally affect the body's respiratory system and the cardiovascular system. Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, and the individual's health status and genetics.

Organic matter[ edit ] In the water quality monitoring found almost all rivers with high levels of BOD a measure of pollution with organic matter. The levels of BOD are severe near the cities and major towns.

In rural parts of India, the river BOD levels were sufficient to support aquatic life. During , 33 percent of all water quality monitoring stations reported a total coliform levels exceeding those levels, suggesting recent effort to add pollution control infrastructure and upgrade treatment plants in India, may be reversing the water pollution trend.

Since , Indian wastewater treatment plant market has been growing annually at the rate of 10 to 12 percent.

The basic definition of land pollution is the destruction and contamination of the land through the direct and indirect actions of humans. The pollution results in changes to the land, such as soil erosion. Some of the changes are irreversible, while others are not.

The effects of land pollution do not necessarily appear overnight. It is the result of long-term destruction from human activities.

For instance, the damage from chemicals from an oil spill can take months or even years to be fully realized. Causes of Land Pollution There are several known causes of land pollution. Of those, there are six factors that contribute more than others. Deforestation and soil erosion When forests are cleared for development and to meet the demand for wood supply, the soil is loosened in the process.

Without the protection of the trees, the land becomes barren over time and starts to erode. Agricultural chemicals Part of the farming process often involves the use of harmful pesticides and insecticides to protect crops.

However, the chemicals can cause the land to become barren. The once-fertile soil is then more susceptible to environmental elements, such as the wind. Industrialization The Industrial Revolution may have resulted in significant positive changes to the economy and society, but it also led to significant pollution of the land.

Through unsafe disposal practices for chemicals used in manufacturing, poor regulation, and the overwhelming number of industries and factories that are polluting the land daily, industrialization has become one of the main contributors to the pollution problem.

Mining The mining process can lead to the creation of large open spaces beneath the surface of the earth. This can result in the land caving in, which compromises the integrity of the land. Mining also results in harmful chemicals, such as uranium, being disturbed and released into the environment.
