Water pollution

Water pollution is broad term that includes contamination of different water bodies such as lakes, rivers, oceans, and groundwater. Water pollution is caused by pollutants, mostly in form of different chemicals that are discharged either directly or indirectly into the water bodies without the adequate treatment to remove their harmful effects. Water pollution is not only huge ecological problem but also huge health problem. It is believed that water pollution is the leading worldwide cause of deaths and diseases responsible for around 15,000 deaths each day. Water pollution is especially serious issue in two fast growing economies, China and India. Some latest reports suggest that more than 500 million Chinese lack access to safe drinking water while in India 700 million people have no access to proper toilet. The two main causes of water pollution are waste water and sewage waste. Each year the world generates around 400 billion tons of industrial waste, and lot of this waste gets discharged into different water bodies causing serious water pollution problem. To determine the level of water pollution science usually takes samples that are afterwards analyzed by different chemical, biological and physical testing. Several studies have confirmed the link between the water pollution and high miscarriage rates. Water pollution is also connected with the lower IQ rates among affected population. Diarrhea, caused by water pollution, is worldwide…

Natural Resources: Water Pollution Nowadays the entire world has a range of environmental problems which concerns scientist, environmentalists and common people who care about the Planet.

Foreword Environmental pollution is a major global concern. When sources of water pollution are enumerated, agriculture is, with increasing frequency, listed as a major contributor. As nations make efforts to correct abuses to their water resources, there is a need to determine the causes of water quality degradation and to quantify pollution contributions from many sources. Until such time as adequate facts are made available through research to delineate causes and sources,…

Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. CAUSES : Indrustries Automobiles and domestic fuels High proportion of undersirable gases, such as sulphur dioxide and carbono monoxide The number one way to prevent air pollution is to walk or bike more and drive less.
