Pollution causes effects and control pdf
Environmental Pollution - Causes, Effects and Control MeasuresAir pollution occurs when harmful or excessive quantities of substances including gases, particles, and biological molecules are introduced into the Earth's atmosphere. Air pollution in India is a serious issue, ranking higher than smoking, high blood pressure, child and maternal malnutrition, and risk factors for diabetes. In urban areas, most emissions come from vehicles and industry, whereas in rural areas, much of the pollution stems from biomass burning for cooking and keeping warm. In autumn and winter months, large scale crop residue burning in agriculture fields — a low cost alternative to mechanical tilling — is a major source of smoke, smog and particulate pollution. The Air Prevention and Control of Pollution Act was passed in to regulate air pollution and there have been some measurable improvements. However, the Environmental Performance Index ranked India out of countries.

Pollution: Causes Effects and Controls 3rd edition
When we talk about air or water pollution , the reactions garnered are stronger. This is because we can see the effects caused by the pollutants and their extent very clearly. It is normal human psychology to believe in what you see first hand. Our land, on the other hand, is living a nightmare too. We may not be able to see the effects with clarity, but l and is being polluted and abused constantly and we are unable to calculate the damages incurred.
Water pollution has become a growing concern over the last century as more and more waste is being disposed of in our oceans, rivers and lakes. It is also creating issues in the oceans ecosystem and hurting the animals and plant life that rely on the ocean and rivers for their survival. This article will provide you with an in depth explanation of what water pollution is, the causes and effects associated with water pollution and what can be done to prevent or even reverse the condition of water pollution. Without proper disposal or filtration of these pollutants they can spread throughout the water and effect all living animals and organisms that come into contact with it by contaminating any living thing that requires water for survival. In addition to harming animals water pollution can also affect plants, trees, the soil and other natural materials and resources of the earth.
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution is often classed as point source or nonpoint source pollution. In , pollution killed 9 million people in the world. Major forms of pollution include: Air pollution , light pollution , littering , noise pollution , plastic pollution , soil contamination , radioactive contamination , thermal pollution , visual pollution , water pollution. Air pollution has always accompanied civilizations. Pollution started from prehistoric times , when man created the first fires.

Effects of Land Pollution
Pollution: Causes, Effects and Control is the fourth edition of a best-selling introductory level book dealing with chemical and radioactive pollution in its broadest sense. The scope of the book ranges from the sources of pollutants and their environmental behaviour, to their effects on human and non-human receptors, to the technologies and strategies available for control. The fourth edition has been wholly revised and updated from the previous edition due to the rapid pace of developments in this field. Topics covered include chemical pollution of freshwater and marine environments, drinking water quality, water pollution biology, sewage and its treatment, toxic wastes, air pollution and atmospheric chemistry, control of pollutant emissions, land contamination, solid waste management, clean technologies, persistent organic pollutants in the environment, environmental radioactivity, health effects of environmental chemicals, legal control of pollution and integrated pollution control. There is a completely new chapter on Clean Technologies and Industrial Ecology, reflecting the growing importance of pollution prevention as opposed to end-of-pipe solutions. Whilst originally intended as an introductory reference work for professionals within the field, the book has been widely adopted for teaching purposes at the undergraduate and postgraduate level.

Land pollution is a serious problem that impacts humans, animals, and the earth. Without taking measures now to reduce pollution levels, permanent changes to the land can occur. The adverse changes to the environment due to land pollution are subtle, but the problem is much bigger than it appears. Even though most people have a general understanding of pollution , they may not realize the significance of land pollution. Here is a look at land pollution, its causes, its impact, and solutions to the problem.
