Environmental Pollution and Effects

Description

The main objective of this book is to convey to the readers an uptodate information on environmental pollution in the significant contribution of various experts in the areas of their specialization. Environmental Pollution occurs when pollutants contaminate the surroundings; which brings about changes that affect our normal lifestyles adversely. Pollutants are the key elements or components of pollution which are generally waste materials of different forms. Pollution disturbs our ecosystem and the balance in the environment. With modernization and development in our lives pollution has reached its peak; giving rise to global warming and human illness. Environmental pollution has existed for centuries but only started to be significant following the industrial revolution in the 19th century. Pollution occurs when the natural environment cannot destroy an element without creating harm or damage to itself. The elements involved are not produced by nature, and the destroying process can vary from a few days to thousands of years (that is, for instance, the case for radioactive pollutants). In other words, pollution takes place when nature does not know how to decompose an element that has been brought to it in an unnatural way. Pollution must be taken seriously, as it has a negative effect on natural elements that are an absolute need for life to exist on earth, such as water and air. Indeed, without it, or if they were present on different quantities, animals ? including humans ? and plants could not survive. We can identify several types of pollution on Earth: air pollution, water pollution and soil pollution. Aim of this book is to bridge the gap between traditional materials on pollution and quantitative and technical aspects that are the essence of most advanced environmental science.
