Sources of pollution

What are the worst sources of pollution? Source of Pollution Sources of air emissions from pulp and paper mills. This chapter introduces the major sources of pollution,. Air Pollution Law and Regulations.

Successful Management of Coral Reef-Watershed Networks.

Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollution is often classed as point source or nonpoint source pollution. Non-Point Source Pollution. Non-point source pollution does not come from a specific source. Instea it originates from many places, or from a widespread area.

There are different types of pollution : water pollution , air pollution , solid waste pollution and noise pollution. All of these can be found in urban areas. The point sources are easy to identify, monitor and control, whereas the non-point sources are hard to control.

Environmental Pollution , Its Sources and Effects Environmental pollution. It has a hazardous effect on the natural world and on the activities. Industrial activities: The industries all over the world that brought prosperity and affluence,. Dumping solid waste: Household. A point source of pollution is a single identifiable source of air, water, thermal, noise or light pollution.

A point source has negligible extent, distinguishing it from other pollution source geometries (such as nonpoint source or area source ). The sources are called point sources because in mathematical. Of all sources marine pollutions, comes from the land. There are many causes for water pollution but two general categories exist: direct and indirect contaminant sources. Direct sources include effluent outfalls from factories, refineries, waste treatment plants etc.

Various Causes of Water Pollution 1. Industries produce a huge amount of waste which contains toxic chemicals. The sewage and wastewater that is produced by each household is chemically. Mining is the process of crushing the. Sources are commonly classified into three broad groups: primary, secondary, and re-emission sources.

A primary source from the direct emissions from an air pollution source. In contrast, a secondary source from the formation of a pollutant in the atmosphere from the chemical reaction of precursors emitted from air pollution sources.

Burning charcoal, woo and crop waste release Carbon Monoxide (CO), Carbon Dioxide (CO2), and particulate matter into the atmosphere that potentially causes air pollution. In some regions, waste is incinerated instead of being land-filled or recycled and as such, it substantially contributes to air pollution. Unwanted garbage from industrial activities like glass, metals and wood are the other kinds of wastes which industries generate.

When these wastes are left on the soil’s surface, they change the chemical composition of the soil. The physical qualities of soil are also altered. Such sources of soil pollution make the soil harmful as well as barren.

Most nonpoint source pollution occurs as a result of runoff. Human beings largely depend on their environment for survival. PM stands for particulate matter (also called particle pollution ): the term for a mixture of solid particles and liquid droplets found in the air. Water pollution is categorized into point source , non-point source, and groundwater.

Point source water pollution occurs when the contaminants enter a water body from a single identifiable source while non-point source occurs as a result of cumulative effects of different amounts of contaminants. Forest fires, volcanic eruption, dust storms, decaying organic matters are the causes of air pollution from the natural sources. On the other han auto mobiles, agriculture, power plants industries etc are the man-made sources that cause air pollution to exceed. Industrial wastes: There are two kinds of wastes that are generated from industrial activities: unused chemicals and unwanted industrial garbage.

Some of the sources of soil pollutions are discussed below: 1. Unused chemicals like fly ash, sludge, plastics and sawdust are some of the chemicals that are discharged from industries. Some are emitted directly from a source, such as construction sites, unpaved roads, fields, smokestacks or fires. Most particles form in the atmosphere as a result of complex reactions of chemicals such as sulfur dioxide and nitrogen oxides, which are pollutants emitted from power plants, industries and automobiles.
