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.

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.

Air pollution

Damage caused to materials exposed in the atmosphere constitutes one of the most important direct effects of acidifying air pollutants. Systematic field and laboratory investigations performed in the recent decade in many countries have contributed to a considerable increase in the knowledge on the mechanisms of the effects of pollutants, on the quantification of damage and on the assessment of the cost of damage. Beside the very important role of SO 2 for several materials also studies of the direct or synergistic effect of NO x and O 3 have contributed to the understanding of the complex pollution effects. Even if there are still considerable gaps of knowledge it seems that NO x and O 3 may contribute in an important way to the deterioration of several materials also in indoor environments which are important for i. Dose-response relations have been obtained after 4-year exposure showing the effect of dry and wet deposition on corrosion of several material groups. Also the effect of micro- and mesoclimate on corrosion of building materials like plaster and bricks in different positions on buildings and locations within an urban area has been subject to systematic studies. Results from the studies are used i.

Carbon monoxide CO —a colorless, odorless, tasteless, and toxic air pollutant—is produced in the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, oil, coal, and wood. The largest anthropogenic source of CO in the United States is vehicle emissions. Breathing the high concentrations of CO typical of a polluted environment leads to reduced oxygen O 2 transport by hemoglobin and has health effects that include headaches, increased risk of chest pain for persons with heart disease, and impaired reaction timing. In the s, vehicle emissions led to increased and unhealthful ambient CO concentrations in many U. The locations that continue to have high concentrations of CO tend to have topographical or meteorological characteristics that exacerbate pollution; for example, strong temperature inversions or the existence of nearby hills that inhibit wind flow may limit pollutant dispersion.

Air pollution is understood to directly and indirectly contribute to a range of social, economic and environmental impacts. Widespread and fast action to reduce short-lived climate pollutant emissions has the potential to reduce the amount of warming that would occur over the next few decades by as much as 0. Ironically perhaps, the air pollution that is partially created by buildings are directly impacting their ability to perform in a sustainable way. Skip to main content. Air Quality in the Built Environment. Impacts of Air Pollution from and on the Built Environment Air pollution is understood to directly and indirectly contribute to a range of social, economic and environmental impacts.

Direct and indirect air pollution effects on materials including cultural monuments

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.

Air pollution consists of chemicals or particle s in the air that can harm the health of humans, animals, and plants. It also damages buildings. Pollutant s in the air take many forms. They can be gases, solid particles, or liquid droplets. Sources of Air Pollution Pollution enters the Earth's atmosphere in many different ways.

Impacts of Air Pollution from and on the Built Environment

Никакого кольца. Я так близок к цели, - подумал. - Ein Ring! - повторил Беккер, но дверь закрылась перед его носом. Он долго стоял в роскошно убранном коридоре, глядя на копию Сальватора Дали на стене. Очень уместно, - мысленно застонал .

We apologize for the inconvenience...

 - Стратмор кивнул в сторону лаборатории систем безопасности.  - Чатрукьян уже, надеюсь, ушел. - Не знаю, я его не видела.

Environmental and Health Impacts of Air Pollution: A Review

Он стоит десять раз по двадцать миллионов. - Увы, - сказал Нуматака, которому уже наскучило играть, - мы оба знаем, что Танкадо этого так не оставит. Подумайте о юридических последствиях. Звонивший выдержал зловещую паузу. - А что, если мистер Танкадо перестанет быть фактором, который следует принимать во внимание. Нуматака чуть не расхохотался, но в голосе звонившего слышалась подозрительная решимость. - Если Танкадо перестанет быть фактором? - вслух размышлял Нуматака.

 Чтобы он получил второй ключ. - Что еще за второй ключ. - Тот, что Танкадо держал при. Сьюзан была настолько ошеломлена, что отказывалась понимать слова коммандера. - О чем вы говорите. Стратмор вздохнул. - У Танкадо наверняка была при себе копия ключа в тот момент, когда его настигла смерть.


The materials most sensitive to pollutants are calcareous building stones and ferrous metals. Manifestations of damage include losses of mass, changes in.
