Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. Read here more about 40 facts of air pollution. Another way of looking at air pollution could be any substance that holds the potential to hinder the atmosphere or the well being of the living beings surviving in it.

What is Air Pollution?

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. Most of these emissions are produced by the industry, so this can be remedied by social responsibility and action by companies and factories. Climate Change is another consequence of global warming.

SOIL POLLUTION

We tend to look skywards when talking about pollution, but this problem is not confined to our skies. The soil in which our fruit and vegetables grow is also suffering its consequences, the effects of which getting to us directly, for instance, through the aforementioned foodstuffs. The time has come to look after what lies under our feet! Soil pollution is mostly caused by chemical substances produced by human activity. The soil is the skin of the earth, a mantle full of scars, thousand-year-old wrinkles and more recent injuries caused both by man and nature itself.

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.

Air pollution is the presence of gases and solid particles that result in adverse health effects. They are either natural or human-made. Common air pollutants include ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, lead, and particulate matter. Here's what you need to know about air pollution, and what's being done about it. The greatest threats to human health In the United States are ground-level ozone and airborne particles. The first threat, ground-level or "bad" ozone, is not emitted directly into the air. It is created by chemical reactions between oxides of nitrogen NOx and volatile organic compounds VOC in the presence of sunlight.


Air pollution occurs when gases, dust particles, fumes (or smoke) or odour are introduced into the atmosphere in a way that makes it harmful to humans, animals and plant. It creates smog and acid rain, causes cancer and respiratory diseases, reduces the ozone layer atmosphere and contributes to global warming.


Water Pollution: Everything You Need to Know

Indoor Air Quality IAQ refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns. Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later. Some health effects may show up shortly after a single exposure or repeated exposures to a pollutant.

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.

The main air pollutants are represented by gases forms, particles in suspension, different ionizing radiation and noise. The particulate forms are: PM10 and PM2. Atmospheric pollutants have a negative effect on the plants; they can have direct toxic effects, or indirectly by changing soil pH followed by solubilization of toxic salts of metals like aluminum.

 Это очень большие деньги. - Конечно. Договорились. Девушка покачала головой. - Как бы я хотела сказать. - Миллион песет? - предложил Беккер.

 Конечно. Я же его личный помощник. - Дай мне. Бринкерхофф не верил своим ушам. - Мидж, я ни под каким видом не пущу тебя в кабинет директора. - Ты должен это сделать! - потребовала она и, отвернувшись, начала что-то печатать на клавиатуре Большого Брата.  - Мне нужен список очередности работы на ТРАНСТЕКСТЕ.

 Конечно, я буду счастлив тебе заплатить.  - И он начал отсчитывать купюры. Глядя, как он шелестит деньгами, Меган вскрикнула и изменилась в лице, по-видимому ложно истолковав его намерения. Она испуганно посмотрела на вращающуюся дверь… как бы прикидывая расстояние. До выхода было метров тридцать.

Дэвид посмотрел ей в глаза: - Ты выйдешь за меня замуж. У нее перехватило дыхание.

Дверь вела прямо во двор. Кардиналу надоело выходить из церкви через главный вход подобно обычному грешнику. ГЛАВА 96 Промокшая и дрожащая от холода, Сьюзан пристроилась на диванчике в Третьем узле. Стратмор прикрыл ее своим пиджаком.

Затем щелкнула по кнопке возврат. Компьютер однократно пискнул. На экране высветилось: СЛЕДОПЫТ ОТПРАВЛЕН Теперь надо ждать. Сьюзан вздохнула. Она чувствовала себя виноватой из-за того, что так резко говорила с коммандером.

Он набрал в легкие воздуха. - Вы хотите приделать к Цифровой крепости черный ход. Его слова встретило гробовое молчание.

Сьюзан хотелось закричать: Дэвид, не соглашайся. Это не принесет тебе радости. У нас много денег - какая разница, кто из нас их получает. Но это была чужая епархия. В конце концов ей пришлось смириться.

И тогда она вспомнила .

Снова и снова тянется его рука, поблескивает кольцо, деформированные пальцы тычутся в лица склонившихся над ним незнакомцев. Он что-то им говорит. Но что. Дэвид на экране застыл в глубокой задумчивости.

 Три часа. Стратмор поднял брови. - Целых три часа.

Стратмор хмыкнул. Мысль Сьюзан показалась ему достойной внимания.

    When many of us think of pollution, images of smoggy cities and litter-infested oceans come to mind.
