However‚ it is becoming increasingly widespread in urban areas that have low levels of sanitation‚ such as in poor areas of large cities in the developing world. Most cases of leptospirosis are sporadic (infrequent)‚ although large

Paper Abstract My report was based on the how ground water may be affected by myriad containments present in our experiment and in our everyday . Surprisingly when vinegar was filtered through dirt it came out fairly clean. This surprised me because I would never believed that vinegar had such a profound effect on water considering its oily nature. I was convinced that vinegar more than the other contaminates would have produced a wider‚ more polluted field. I believed that all the water would

Full of our sewage. • We take water‚ return sewage. • 80% of water leaves as sewage • Cities are growing‚ need more water‚ discharge more pollution. • Dirty water means ill health: biggest cause of children’s death.

parameters that we need to observe. Firstly‚ look at the transparency of the river water. Transparency is the measure of the depth of light that can penetrate into the water (What is water transparency?‚ n.d.). It depends on the amount of particle scattering in the water‚ such as algae and sediment. The lower the turbidity of the water (the higher the transparency)‚ the higher the aesthetic value of the river. High turbidity of water causes by particulate matter can reduce the aesthetic value of the river

of this area. The regulatory measures are not that much practiced to restrict pollution. So the contamination level has reached to a level that the citizens are suffering from different pollution related problems. A detailed level policy frame work and planning implication is essential for the development of the area and for ensuring livable environment. To assess the environmental degradation of heavy metals of water samples‚ heavy metals and organic carbon content of sediment were analyzed by

Pollution Introduction Pollution is the introduction of contaminants into an environment that causes instability‚ disorder‚ harm or discomfort to the ecosystem i.e. physical systems or living organisms. 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. Pollution became

1. What transitions has Earth gone through and why? The young earth was anything but habitable. Radioactive elements decaying within its mass and impacts from debris raining down form space generated intense heat. There was no life during this era. Is called the Hadean era and was formed about 4.5 billion years ago. Hadean comes from the Greek word Hades which means “Hell”. That’s how hot the Earth’s temperature was. The next phase in the Earth’s history was the Archean era. It existed

Humans largely influence the factors that determine water quality‚ as they depose off their waste in water and add all kinds of substances and contaminants that are not naturally present. We now know more than 70.000 water pollutants. 2. About 450 cubic kilometres of wastewater are carried into coastal areas by rivers and streams every year. These pollution loads require an additional 6‚000 cubic kilometres of freshwater to dilute the pollution. This amount equals to

Lakes are relatively small to large water bodies surrounded by land on all sides sustaining an ecosystem in and around them. Lakes have been an integral part of the ecological system by providing natural abode for plants‚ animals and microorganisms. Increase in urbanization and industrialization has led to the destruction and in the reduction of lakes in the city of Bangalore‚ Surviving lakes in Bangalore are reduced to cesspools due to direct discharge of industrial effluents and unregulated dumping
