Jerry Spiegel and Lucien Y. Over the course of the twentieth century, growing recognition of the environmental and public health impacts associated with anthropogenic activities discussed in the chapter Environmental Health Hazards has prompted the development and application of methods and technologies to reduce the effects of pollution. In this context, governments have adopted regulatory and other policy measures discussed in the chapter Environmental Policy to minimize negative effects and ensure that environmental quality standards are achieved. The objective of this chapter is to provide an orientation to the methods that are applied to control and prevent environmental pollution. The basic principles followed for eliminating negative impacts on the quality of water, air or land will be introduced; the shifting emphasis from control to prevention will be considered; and the limitations of building solutions for individual environmental media will be examined. It is not enough, for example, to protect air by removing trace metals from a flue gas only to transfer these contaminants to land through improper solid waste management practices.

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 worldwide. Major forms of pollution include air pollution , light pollution , litter , noise pollution , plastic pollution , soil contamination , radioactive contamination , thermal pollution , visual pollution , and water pollution. Air pollution has always accompanied civilizations. Pollution started from prehistoric times , when man created the first fires.

Theory of Environmental Pollution is one among them. In this article, we have thoroughly discussed the types, causes and impacts of different pollutions affecting humankind. Kidney problems, irritation in eyes, nose and throat, asthma, hypertension and carcinogenic effects on lungs. The improvement of nutrients in water bodies causes eutrophication. Domestic waste discharge, agricultural waste, land drainage and industrial waste in a water body leads to a rapid increase in nutrients in a water body which initiates early ageing of water bodies.

Promote measures to reduce pollution from mobile and stationary sources. Support environmentally sound policies that reduce energy growth reates, emphasize energy conservation and encourage the use of renewable resources.

The present paper is an attempt to examine the trend in the level of environmental pollution in Delhi and measures taken to control it. The data have been analyzed from various secondary sources of data. The analysis reveals that rapid population growth continues to be a matter of concern as it has manifold effects, one of the most important being environmental pollution. Densely populated and rapidly growing Delhi mega city is often entombed in a pall of pollution from vehicles, sewage and liquid wastes generated by human settlement and uncontrolled pollution from industries. The recent pollution control measures taken by central government reduced the environmental pollution up to some extent.

Расстроенный, Беккер повесил трубку.

Фонтейн свирепым взглядом заставил его замолчать. - Вы меня слышите? - вмешался Беккер, чувствуя себя неловко.  - Вы все время говорите о произвольном наборе букв.
