Pollutant control
Pollutant control refers to the measures and strategies implemented to minimize or eliminate the release of harmful substances into the environment. This can include regulations, technologies, and practices aimed at reducing air, water, and soil pollution. The goal of pollutant control is to protect human health, ecosystems, and natural resources from the negative impacts of pollution.

1 Environmental Pollution: Control and Prevention Over the course of the twentieth century, growing recognition of the environmental and public health impacts associated with anthropogenic activities 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 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. Integrated multimedia solutions are required. Approach of The Pollution Control The environmental consequences of rapid industrialization have resulted in countless incidents of land, air and water resources sites being contaminated with toxic materials and other pollutants, threatening humans and ecosystems with serious health risks. More extensive and intensive use of materials and energy has created cumulative pressures on the quality of local, regional and global ecosystems. Before there was a concerted effort to restrict the impact of pollution, environmental management extended little beyond laissez-faire tolerance, tempered by disposal of wastes to avoid disruptive local nuisance conceived of in a short-term perspective. The need for remediation was recognized, by exception, in instances where damage was determined to be unacceptable.

Although this process is not as expensive as the treatment of the waste, it might become a financial risk by affecting the cost of the manufacturing process without adding any worth (Choe & Fraser, 1999; Minghua et al., 2009). Although the approach of controlling pollution has been effective in achieving potential success in improving short-term local problems of pollution, it has failed to address the combined problems caused by pollution at a regional or global level, i.e., acid rain or ozone depletion, respectively (Kanagaraj et al., 2015; Zaman, 2015; 2016). The reduction of pollution to the lowest possible level to enhance the quality of life is the basic objective of program-oriented health by controlling environmental pollution. All pollution aspects (i.e., land, air, and water, etc.) are covered by policies and programs of environmental contamination control, whose priorities and implications differ from land to land, and coordination among areas, i.e., city planning, industrial development, transportation policies, and water resources development is also involved in them (Eighmy et al., 1995; Hartlén, 1996). The North-American Great Lakes is a case study that has been provided by Thomas Tseng, Victor Shantora and Ian Smith as an example of the environmental impacts of pollution caused by different media subjected to several stresses. A particular analysis of the restricted effectiveness of the contamination control model, in treating the pollutants that are emitted to the environment, has been made. Illustrations of the consequences of the practices that are related to control as well as prevention have been given by aiming at the method being followed in one land and its international repercussions (Hostovsky, 2006).

- Pollutants can enter the environment naturally or can be caused by human activities (for example from burning coal). Most pollution from anthropogenic activities occurs in or near urban and industrial areas, where pollutants are concentrated. Industrialized agriculture also is the major source of pollution.
- Pollutants could transform, metabolize, degrade, or be enriched in the environment through biological, physical, or chemical reactions, which result in property and concentration change in pollutants and then cause different harmful effects.
- Pollutants affect the human body in a long time through air, water, soil and food in various ways, for example, disruption of life-support systems for humans and other species; damage to wildlife, human health, and property; and nuisances such as noise and unpleasant smells, tastes, and sights.
Two approaches are commonly used to deal with pollution: 1 preventing pollution that comes into the environment or 2 cleaning it up if it did. Pollution prevention or pollution source control can reduce or eliminate the generation of pollutants. Pollution can be prevented by the following “five Rs” of resource use: refuse, replace, reduce, reuse, and recycle.Theory is the foundation and precondition for technology and management innovation, which determines the development, practice, and integration of environmental pollution control. The theory of sustainable development requires legal protection, technical support, and management practice to build, in order to ultimately be built into national/regional environmental security and early warning system.

One of the greatest puzzles in environmental law is the question of how to manage pollution: the greater-than-desired concentration of dangerous or impure substances. Pollution is often classified and controlled by the medium through which humans become exposed to dangerous substances; thus, air pollution, water pollution, and soil pollution are commonly distinguished from one another and managed through distinct pollution-control regimes. Pollution is also sometimes classified by the reason for its generation: Potentially dangerous substances may be regulated differently depending upon whether they have been purposefully generated because they offer benefits as well as dangers, as with toxic substances like pesticides or pharmaceuticals, or whether they are waste byproducts of other substances or processes that are useful in industry or in daily life.The stakes of pollution control vary from minimal to enormous, depending upon the type and extent of the pollution being controlled. One form of pollution—anthropogenic emissions of greenhouse gases, leading to global climate change—is now often viewed as the greatest problem of our time. The stakes and complexity of climate change are indeed so great that we devote an entire chapter to it. Even the stakes of conventional pollutants can be enormous, however; as an example, some estimates suggest that 200,000 Americans die each year from air pollution (Calazzo et al., 2013)—even as the legal protections of the Clean Air Act prevent another 200,000 premature deaths (Environmental Protection Agency, 2011).In part because of the many types of pollution, and in part because pollution can have such an extraordinary impact on human health and environmental quality, pollution control is a massive field of law. In the United States, pollution control incorporates a number of sprawling statutes and regulatory regimes, including the Clean Air Act, the Clean Water Act, the Toxic Substances Control Act, the Resource Conservation and Recovery Act, the “Superfund,” and the Safe Drinking Water Act. The length of the Clean Air Act alone is sometimes compared to that of the U.S. tax code (Revesz, 2015). Yet pollution and pollution exposure is affected not only by national or federal law, but also by laws and policies at the international, state, and local level. Furthermore, because of the breadth and complexity of the legal strategies applied to pollution control, it is common for many legal institutions to be involved in controlling pollution. In the United States, for example, many decisions are coordinated through federal regulatory processes in cooperation with state entities, Indian tribes, and local and municipal governments, as well as with private stakeholders, including industry and nonprofit environmental groups.
