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.
Environmental and Health Impacts of Air Pollution: A Review
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.

Ground-level ozone is formed when volatile organic compounds VOCs and oxides of nitrogen NOx react with the sun's ultraviolet rays. The primary source of VOCs and NOx is mobile sources, including cars, trucks, buses, construction equipment and agricultural equipment. Ground-level ozone reaches its highest level during the afternoon and early evening hours. High levels occur most often during the summer months. It is a strong irritant that can cause constriction of the airways, forcing the respiratory system to work harder in order to provide oxygen. Particulate Matter is a complex mixture that may contain soot, smoke, metals, nitrates, sulfates, dust, water and tire rubber.
Air pollution is the presence of substances in the atmosphere that are harmful to the health of humans and other living beings , or cause damage to the climate or to materials. There are different types of air pollutants, such as gases such as ammonia , carbon monoxide , sulfur dioxide , nitrous oxides , methane and chlorofluorocarbons , particulates both organic and inorganic , and biological molecules. Air pollution may cause diseases, allergies and even death to humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment. Both human activity and natural processes can generate air pollution. Air pollution is a significant risk factor for a number of pollution-related diseases , including respiratory infections , heart disease , COPD , stroke and lung cancer. Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, and the individual's health status and genetics.
Water Pollution: Everything You Need to Know
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:.
Water pollution: how to protect our source of life
Мой Бог. Это была настоящая красотка. - Спутница? - бессмысленно повторил Беккер. - Проститутка, что. Клушар поморщился: - Вот .
Переступив порог, она вовремя успела ухватиться за дверную раму и лишь благодаря этому удержалась на ногах: лестница исчезла, превратившись в искореженный раскаленный металл. Сьюзан в ужасе оглядела шифровалку, превратившуюся в море огня. Расплавленные остатки миллионов кремниевых чипов извергались из ТРАНСТЕКСТА подобно вулканической лаве, густой едкий дым поднимался кверху. Она узнала этот запах, запах плавящегося кремния, запах смертельного яда. Отступив в кабинет Стратмора, Сьюзан почувствовала, что начинает терять сознание.
Вы должны немедленно покинуть шифровалку.
