Factory pollution is also called as industrial pollution that is main cause of emissions, effluents and wastes which come out during manufacturing of goods and services. If all gaseous emissions, effluents spillage and wastes of a factory are not handled in an environment-friendly manner it harms the surrounding environment.
In less developed countries the enforcement mechanism of environmental laws is not strong and well developed. Environmental violators easily dodge the environmental watchdogs at every stage and sometimes get bail from court by offering fake defence. As a result industrial pollution in less developed countries is far higher than the developed ones.
Factory processes involve varied combinations of cleaning, painting and heating, while other raw material or appliance treatments release volatile organic compounds into the atmosphere. These are carbon- or hydrocarbon-based chemicals that quickly evaporate in the air. In the presence of sunlight, they react with other air pollutants like sulfur or nitrogen oxides from vehicle exhausts to create peroxyacetyl nitrates, commonly known as photochemical smog.
Pollution of air, water and soil take a huge number of years to recover. Industry and engine vehicle fumes are the most obvious toxins. Substantial metals, nitrates and plastic are poisons in charge of pollution. While water contamination is brought about by oil slicks, acid rain, and urban sprawl; air contamination is created by different gasses and poisons discharged by businesses and manufacturing plants and burning of fossil fills.
Noise pollution is the disturbing noise with harmful impact on the activity of human or animal life. The source of outdoor noise worldwide is mainly caused by machines and transportation systems, motor vehicles engines and trains.Outdoor noise is summarized by the word environmental noise.High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease.
Aircraft noise is noise pollution produced by any aircraft or its components, during various phases of a flight: on the ground while parked such as auxiliary power units, while taxiing, on run-up from propeller and jet exhaust, during take off, underneath and lateral to departure and arrival paths, over-flying while en route, or during landing.
Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise which increases with higher vehicle speeds

Poor urban planning may give rise to noise pollution
The waste materials that cause land pollution are broadly classified as municipal solid waste (MSW, also called municipal refuse), construction and demolition (C&D) waste or debris, and hazardous waste. MSW includes nonhazardous garbage, rubbish, and trash from homes, institutions (e.g., schools), commercial establishments, and industrial facilities.
Land pollution simply means degradation of earth’s surface as a result of human activities like mining, littering, deforestation, industrial, construction and agricultural activities. Land pollution can have huge environmental impact in the form of air pollution and soil pollution which in turn can have adverse effect on human health.
Deforestation, clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use.Examples of deforestation include conversion of forestland to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests.About 30% of Earth's land surface is covered by forests.
Deforestation occurs for multiple reasons: trees are cut down to be used for building or sold as fuel, (sometimes in the form of charcoal or timber), while cleared land is used as pasture for livestock and plantation. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide.
Deforestation has also been used in war to deprive the enemy of vital resources and cover for its forces. Modern examples of this were the use of Agent Orange by the British military in Malaya during the Malayan Emergency and the United States military in Vietnam during the Vietnam War. As of 2005, net deforestation rates have ceased to increase in countries with a per capita GDP of at least US$4,600.Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland.
Disregard of ascribed value, lax forest management and deficient environmental laws are some of the factors that allow deforestation to occur on a large scale. In many countries, deforestation, both naturally occurring and human-induced, is an ongoing issue. Deforestation causes extinction, changes to climatic conditions, desertification, and displacement of populations as observed by current conditions and in the past through the fossil record.
