Air pollution control , the techniques employed to reduce or eliminate the emission into the atmosphere of substances that can harm the environment or human health. The control of air pollution is one of the principal areas of pollution control , along with wastewater treatment , solid-waste management , and hazardous-waste management. Air is considered to be polluted when it contains certain substances in concentrations high enough and for durations long enough to cause harm or undesirable effects. These include adverse effects on human health, property, and atmospheric visibility.

It is about economic accountability. Any organisation or individual is responsible for handling and taking care of the waste they produce and should be accountable for any damage that it causes. Imagine a factory that produces many types of wastes that potentially damage the air, water and soil. The polluter pays principle encourages the factory to treat the waste before it is released.
One of our era's greatest scourges is air pollution, on account not only of its impact on climate change but also its impact on public and individual health due to increasing morbidity and mortality. There are many pollutants that are major factors in disease in humans. Among them, Particulate Matter PM , particles of variable but very small diameter, penetrate the respiratory system via inhalation, causing respiratory and cardiovascular diseases, reproductive and central nervous system dysfunctions, and cancer. Despite the fact that ozone in the stratosphere plays a protective role against ultraviolet irradiation, it is harmful when in high concentration at ground level, also affecting the respiratory and cardiovascular system. Furthermore, nitrogen oxide, sulfur dioxide, Volatile Organic Compounds VOCs , dioxins, and polycyclic aromatic hydrocarbons PAHs are all considered air pollutants that are harmful to humans. Carbon monoxide can even provoke direct poisoning when breathed in at high levels. Heavy metals such as lead, when absorbed into the human body, can lead to direct poisoning or chronic intoxication, depending on exposure.
Environmental pollution or simply pollution refers to undesirable changes occurring in the physical, chemical, and biological composition of natural environment consisting of air, water, and soil. Pollution also means the presence of harmful pollutants in an environment that makes this environment unhealthy to live in. Natural environment has an inbuilt capacity to replenish the losses or reduction in its constituents to restore it as sustainable and healthy as required. Ever expanding population and evolution of man into modern homo sapiens have led to rapid urbanization, industrialization and unprecedented rise in human habitations. All these human endeavors have, in turn, virtually perpetuated deforestation, loss of habitats for flora and fauna, depletion of natural resources at a large scale over the last couple of centuries, which have told upon the inherent resilience of the natural environment. As a result, natural environment continues to be undesirably polluted.

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.
Environmental sustainability implies meeting our current needs without jeopardizing the right and the ability of future generations to meet theirs. Opportunities should be identified and taken to reduce the production of wastes and the use of toxic materials, to prevent soil, water, and air pollution and to conserve and reuse resources, as feasible. Environmental pollution with its health impacts is a key issue for sustainable environment United Nations General Assembly Sustainability and sustainable development focuses on balancing that fine line between competing needs, our need to move forward technologically and economically, and the needs to protect the environments in which we and others live. Sustainability is not just about the environment Kates et al.

Environmental Pollution and Control, Third Edition focuses on the aspects of environmental engineering science and technology, including water pollution, wastewater, sludge treatment, and water pollution legislation. The book first elaborates on environmental and water pollution and measurement of water quality. Discussions focus on chemical oxygen demand, bacteriological measurements, heavy metals, effect of pollution on streams, lakes, and oceans, biodegradation, population responses, and exposure and latency.
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.

Ты ничего не понимаешь! - кричал Хейл. - На его компьютере уже стоял жучок! - Он говорил, стараясь, чтобы его слова были слышны между сигналами. - Этот жучок вмонтировал кто-то другой, и я подозреваю, что по распоряжению директора Фонтейна. Я просто попал на все готовое. Поверь. Поэтому я и узнал о его намерении модифицировать Цифровую крепость.
Next we discuss our environmental problems within the framework of ethics. We begin by showing how the most basic concepts of environmental pol- lution that.
