You were introduced to wastes and pollutants in Study Session 1, where we discussed the interactions between humans and our environment. Pollution was defined as the introduction into the environment of substances liable to cause harm to humans and other living organisms. Many human activities pollute our environment, adversely affecting the water we drink, the air we breathe, and the soil in which we grow food.

WATER POLLUTION

The water they say is life, and indeed they were right. Water is an essential element in both domestic as well as industrial purposes. However, a closer inspection of our water resources today gives us a terrible shock. Water and air, the two essential fluids on which all life depends, have become global garbage cans. It is the abuse of lakes, ponds, oceans, rivers, reservoirs,.

Water pollution is the contamination of water bodies , usually as a result of human activities. Water bodies include for example lakes , rivers , oceans , aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems. In turn, this can lead to public health problems for people living downstream. They may use the same polluted river water for drinking or bathing or irrigation. Water pollution is the leading worldwide cause of death and disease, e.

Water pollution

The planet keeps nudging us with increasingly extreme droughts, reminding us that water is life. It is an essential resource upon which all living beings depend and it is crucial to all social and economic development, as well as energy production and adaptation to climate change. Nevertheless, we are now facing a gigantic challenge. How do we stop contaminating our rivers, seas, oceans, canals, lakes and reservoirs? Water pollution is endangering the health of millions of people around the world.

Principles and Practice of Environmental Medicine pp Cite as. An ample supply of clean fresh water is essential for the well-being of all organisms. The quality of drinking water, often taken for granted in industrialized nations, is increasingly becoming a matter of concern. The original focus of most water quality improvement programs was on such conventional pollutants as dissolved oxygen, fecal coliform bacteria, suspended sediment, dissolved solids, and phosphorus. Although pathogens in inadequately treated drinking water are still the greatest public health concern related to drinking water, increased industrialization, the widespread use of chemicals in industry and agriculture, and the disposal of large volumes of industrial wastes have drawn attention to the importance of protecting drinking water from contamination with chemical agents. Over 60, chemicals are now being used by industry and agriculture.

Water pollution , the release of substances into subsurface groundwater or into lakes , streams, rivers , estuaries , and oceans to the point where the substances interfere with beneficial use of the water or with the natural functioning of ecosystems. In addition to the release of substances, such as chemicals or microorganisms, water pollution may also include the release of energy , in the form of radioactivity or heat , into bodies of water. Water pollution is the release of substances into bodies of water that makes water unsafe for human use and disrupts aquatic ecosystems. Water pollution can be caused by a plethora of different contaminants, including toxic waste , petroleum , and disease-causing microorganisms. Human activities that generate domestic sewage and toxic waste cause water pollution by contaminating water with disease-causing microorganisms and poisonous substances. Oil spills are another source of water pollution that have devastating impacts on surrounding ecosystems.
