Environmental pollution is the introduction of contaminants into the natural environment that causes adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. Pollution control is a term used in environmental management. It means the control of emissions and effluents into air, water or soil. Without pollution control, the waste products from overconsumption, heating, agriculture, mining, manufacturing, transportation and other human activities, whether they accumulate or disperse, will degrade the environment. In the hierarchy of controls, pollution prevention and waste minimization are more desirable than pollution control.

  In the present book, thirty-five literatures about environmental pollution and its prevention published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on environmental pollution and human health, air pollution, water pollution, soil pollution and so on. We hope this book can demonstrate advances in environmental pollution and its prevention as well as give references to the researchers, students and other related people.
