    both natural and man made sources. Though globally man made pollutants fromcombustion, construction, mining, agriculture and warfare are increasingly significant inthe air pollution equation. [8]Principal stationary pollution sources include chemical plants , coal-fired power plants , oilrefineries ,[12] petrochemical plants, nuclear waste disposal activity, incinerators, large

    livestock farms (dairy cows, pigs, poultry, etc.), PVC factories, metals productionfactories, plastics factories, and other heavy industry. Agricultural air pollution comesfrom contemporary practices which include clear felling and burning of naturalvegetation as well as spraying of pesticides and herbicides [13]

    hurricanes often involve water contamination from sewage, and petrochemical spills from ruptured boats or automobiles . Larger scale and environmentaldamage is not uncommon when coastal oil rigs or refineries are involved. Somesources of pollution, such as nuclear power plants or oil tankers , can producewidespread and potentially hazardous releases when accidents occur.

    In the case of noise pollution the dominant source class is the motor vehicle ,producing about ninety percent of all unwanted noise worldwide.

    Adverse Effects:Adverse air quality can kill many organisms including humans. Ozone pollutioncan cause respiratory disease , cardiovascular disease , throat inflammation,chest pain, and congestion. Water pollution causes approximately 14,000 deathsper day, mostly due to contamination of drinking water by untreated sewage indeveloping countries

    Sulphur dioxide and nitrogen oxides can cause acid rain which lowers the pH value of soil.Nitrogen oxides are removed from the air by rain and fertilise land which canchange the species composition of ecosystems.Soil can become infertile and unsuitable for plants. This will affect other organisms in the food web .Smog and haze can reduce the amount of sunlight received by plants to carry outphotosynthesis and leads to the production of tropospheric ozone whichdamages plants.Invasive species can out compete native species and reduce biodiversity .Invasive plants can contribute debris and biomolecules ( allelopathy ) that can

    alter soil and chemical compositions of an environment, often reducing nativespecies competitiveness .Biomagnification describes situations where toxins (such as heavy metals ) maypass through trophic levels, becoming exponentially more concentrated in theprocess.

    Carbon dioxide emissions cause ocean acidification , the ongoing decrease in thepH of the Earth's oceans as CO2 becomes dissolved.The emission of greenhouse gases leads to global warming which affectsecosystems in many ways.
