unfrozen fresh water is found mainly as groundwater‚ with only a small fraction present above ground or in the air. However‚ water is now being heavily polluted by nobody else but human. So what are the causes and effects of water pollution? The causes of water pollution vary. However‚ we can sum them up in to two groups: One is direct causes and the other is indirect causes. The direct causes are what are dumped directly into water bodies‚ such as raw sewage‚ household waste or chemicals. In developing

Air pollution – contaminants or substances in the air that interfere with human health or produce other harmful environmental effects. Read our “What is Air Pollution?” article for further information. Alternative energy – usually environmentally friendly‚ this is energy from uncommon sources such as wind power or solar energy‚ not fossil fuels. Alternative fuels – similar to above. Not petrol or diesel but different transportation fuels like natural gas‚ methanol‚ bio fuels and electricity. B

Main effects of sound pollution • Deafness‚ temporary or permanent‚ is one of the most prevalent effects of noise pollution. Mechanics‚ locomotive drivers‚ telephone operators etc all have their hearing impairment. • The first and foremost effect of noise is a decrease in the efficiency in working. Research has proved the fact that human efficiency increases with noise reduction. • Too much of noise disturbs the rhythms of working‚ thereby affecting the concentration required for doing a

Air Pollution Essay The Sources and Affects of Air Pollution (topic): Air pollution is the contamination of the air by noxious gases and small particles of solid and liquid matter in amounts that can cause harm to living organisms. Sources of air pollution include: transportation engines such as automobiles‚ power and heat generation‚ industrial processes‚ and the burning of solid waste. The combustion of gasoline and other fuels in automobiles‚ trucks‚ and jet airplanes produce the most common

Pollution is the introduction of contaminants into a natural environment that causes instability‚ disorder‚ harm or discomfort to the ecosystem i.e. physical systems or living organisms.[1] Pollution can take the form of chemical substances or energy‚ such as noise‚ heat‚ or light. Pollutants‚ the elements of pollution‚ can be foreign substances or energies‚ or naturally occurring; when naturally occurring‚ they are considered contaminants when they exceed natural levels. The major forms of pollution

Introduction In China‚ an increasing population and rapid economic growth as well as lax environmental oversight have increased water pollution. Therefore‚ deterioration of drinking water quality continues to be a major problem. Continuous emissions from manufacturing are the largest contributor to lowered drinking quality across the country. China’s major river systems exhibit the scope of the problem. Perhaps 70 percent of their water is so polluted that it has been deemed unsafe for human contact

Environmental pollution is the biggest menace to the human race on this planet today. It means adding impurity to environment. The environment consists of earth‚ water‚ air‚ plants and animals. If we pollute them‚ then the existence of man and nature will be hampered. It is true that trees are being cut down rapidly. Our earth is becoming warmer. If pollution continues‚ the day is not far when our earth will be a boiling pan and become a desert. Or it will be covered with sea water causing destruction

All of these wonderful characteristics are in jeopardy of being destroyed. Not by wars‚ riots‚ or naturals disasters‚ but by air pollution. The volume of pollution in Iran is commonly associated with their domestic fuel production. This production of fuel increased when sanctions were imposed by the United States and European Union several years ago. These sanctions caused a reduction in the amount of imported refined fuel. With the manufacturing and consumption of national fuel rising in Iran‚ the
