Environmental pollution has existed for centuries but only started to be significant following the industrial revolution in the 19th century. The elements involved are not produced by nature, and the destroying process can vary from a few days to thousands of years that is, for instance, the case for radioactive pollutants.

Environmental Pollution

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.

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.

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.

Environmental Pollution: Health Effects and Operational Implications for Pollutants Removal

Environmental pollution is reaching worrying proportions worldwide. Urbanization and industrialization along with economic development have led to increase in energy consumption and waste discharges. The global environmental pollution, including greenhouse gas emissions and acid deposition, as well as water pollution and waste management is considered as international public health problems, which should be investigated from multiple perspectives including social, economic, legislation, and environmental engineering systems, as well as lifestyle habits helping health promotion and strengthening environmental systems to resist contamination [ 1 — 3 ]. Environmental pollutants have various adverse health effects from early life some of the most important harmful effects are perinatal disorders, infant mortality, respiratory disorders, allergy, malignancies, cardiovascular disorders, increase in stress oxidative, endothelial dysfunction, mental disorders, and various other harmful effects [ 4 , 5 ]. Though, short-term effects of environmental pollutants are usually highlighted, wide range of hazards of air pollution from early life and their possible implication on chronic non-communicable diseases of adulthood should be underscored.

The planet keeps nudging us with increasingly extreme droughts, reminding us that water is life. It is an essential resource upon which all living beings depend and it is crucial to all social and economic development, as well as energy production and adaptation to climate change. Nevertheless, we are now facing a gigantic challenge. How do we stop contaminating our rivers, seas, oceans, canals, lakes and reservoirs? Water pollution is endangering the health of millions of people around the world.

The constant pollution of the air has very negative effects on nature and on human health. Those long-term and medium-term effects have become problems that are difficult to solve. In this article, we are listing the main 10 negative effects that air pollution is causing worldwide:. Probably global warming is one of the most worrying effects for scientists and environmentalists. Global warming is a direct consequence of the greenhouse effect, which is produced by the high emission of CO 2 and methane into the atmosphere.

Environmental Pollution: Health Effects and Operational Implications for Pollutants Removal

The main air pollutants are represented by gases forms, particles in suspension, different ionizing radiation and noise. The particulate forms are: PM10 and PM2.

И, наверное, у половины из них - красно-бело-синие волосы. - Sientate! - услышал он крик водителя.  - Сядьте. Однако Беккер был слишком ошеломлен, чтобы понять смысл этих слов. - Sientate! - снова крикнул водитель.

Но как только шифр будет взломан… - Коммандер, а не лучше ли будет… - Мне нужен ключ! - отрезал .
