The constant pollution of the air has very negative effects on nature and on human health.
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.
Jump to navigation. British poet W. This widespread problem of water pollution is jeopardizing our health. Unsafe water kills more people each year than war and all other forms of violence combined. Without action, the challenges will only increase by , when global demand for freshwater is expected to be one-third greater than it is now.
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. When the temperature of the planet increases, there is a disturbance in the usual climatic cycles , accelerating the changes of these cycles in an evident way.
Due to climate change, the mass of the poles is melting, and this is leading to flooding and the rising of sea levels. The gases emitted by industries, power plants, boilers, heating and transport are very toxic. Those gases include sulphur dioxide SO 2 and nitrogen oxides NOx issued into the atmosphere that come from fossil fuels burning. The smog effect or beret effect happens when there is a kind of dark fog concentrated over the cities and fields.
That fog is a load of pollutants and can be of 2 types: sulphurous smog and photochemical smog, both dangerous and harmful to health. Both types of smog are a consequence of industrial and urban action.
However, sulphurous smog has its origin mainly in the use of coal in many industrial processes. That has been reduced in the most advanced countries — nevertheless, there are still many developing countries that do not have treatment protocols for pollutants. Acid rain, climate change and smog all damage the Earth surface. Contaminated water and gases seep into the earth, changing the composition of soils. That directly affects agriculture, changing crop cycles and the composition of the food we all eat.
As the ice masses of the poles melt and sea levels rise, many animal species, whose survival depends on oceans and rivers, are threatened. Currents change, ocean temperatures change and migratory cycles change, and many animals are forced to seek food in environments unknown to them. Deforestation and poor soil quality also mean the disappearance of ecosystems and habitats. And definitively, an imbalance in the behavior of many wild species.
It is probably one of the most obvious and worrying effects for human beings. Pollutants can cause respiratory illnesses and allergies ranging from coughs to asthma, cancer or emphysema. Inhalation of toxic agents directly affects the lungs and other organs that make up the respiratory system. Also, poor oxygenation can lead to cardiovascular problems. Air pollutants also deteriorate and change the constitution of building materials, so many buildings and infrastructure are weakened, eroded or destroyed at an accelerated rate over time.
People develop intolerances and allergies to many agents present in the atmosphere and to other external agents that can go through due to the holes in the ozone layer.
This is because there is a high concentration of chlorofluorocarbons that alter the thickness of the ozone layer. Chlorofluorocarbons CFCs are released using aerosols, industrial refrigerants, solvents and other very harmful chemicals. However, one of the worst damage is skin cancer.
That disease in many cases develops from the direct incidence of ultraviolet light rays on the skin. The ozone layer acts as a filter for those rays. If the ozone layer is thinner, the effectiveness of the filter decreases, letting rays pass, which are very harmful to humans. All those important effects can increase if their causes are not rapidly acted upon.
Most of them are the result of very intense, polluting and uncontrolled industrial activity. Companies around the world have the responsibility to manage, treat and control the pollutants they emit into the atmosphere. Our health and avoiding the destruction of the environment depend on their response.

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.
The volume covers the nature of air pollution; mechanism of the dispersal of air pollution by meteorological factors and from stacks; and its effect upon plants, animals, humans, materials, and visibility. The classification and extent of air pollution problems; air pollution effects on urban atmospheric and weather conditions; and the effects of air pollution on materials and the economy are discussed as well. Engineers, physicians, meteorologists, economists, sociologists, agronomists, and toxicologists will find the book a valuable reference material. Air Pollution 1. Historical Perspective III. Air Pollution as a Problem of the Future 2.
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. The particulate matters have a negative mechanical effect. They cover the leaf blade reducing light penetration and blocking the opening of stomata. These impediments influence strongly the process of photosynthesis which rate declines sharply. Also the leaves of the trees have an important role in retention of the particulate matters; they are mostly affected when the wet and dry atmospheric deposition increase.
Air pollution threatens the health of humans and other living beings in our planet. It creates smog and acid rain, causes cancer and respiratory.
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.
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.
- Все линии устремились к центру. С левого экрана в камеру неотрывно смотрели Дэвид и агенты Смит и Колиандер. На ВР последняя стенка напоминала тонюсенькую пленку. Вокруг нее было черно от нитей, готовых ринуться внутрь.
Я хочу знать. Бринкерхофф уже пожалел, что не дал ей спокойно уйти домой. Телефонный разговор со Стратмором взбесил. После истории с Попрыгунчиком всякий раз, когда Мидж казалось, что происходит что-то подозрительное, она сразу же превращалась из кокетки в дьявола, и, пока не выясняла все досконально, ничто не могло ее остановить. - Мидж, скорее всего это наши данные неточны, - решительно заявил Бринкерхофф. - Ты только подумай: ТРАНСТЕКСТ бьется над одним-единственным файлом целых восемнадцать часов. Слыханное ли это .
ГЛАВА 117 - Трансляция видеофильма начнется через десять секунд, - возвестил трескучий голос агента Смита. - Мы опустим каждый второй кадр вместе со звуковым сопровождением и постараемся держаться как можно ближе к реальному времени. На подиуме все замолчали, не отрывая глаз от экрана. Джабба нажал на клавиатуре несколько клавиш, и картинка на экране изменилась.
the animal life. Environmental damages. Ecologically, air pollution can cause serious environmental. damages to the groundwater, soil, and air.
Семьдесят четыре и восемь десятых, - сказала Сьюзан. - Но я не думаю… - С дороги! - закричал Джабба, рванувшись к клавиатуре монитора. - Это и есть ключ к шифру-убийце. Разница между критическими массами. Семьдесят четыре и восемь десятых. - Подождите, - сказала Сьюзан, заглядывая через плечо Соши.
Нет смысла вбухивать миллиарды долларов в дешифровальный компьютер и одновременно экономить на тех, кто работает на этой превосходной технике. Сьюзан скинула туфли на низких каблуках от Сальваторе Феррагамо и блаженно погрузила обтянутые чулками ноги в густой шерстяной ковер. Высокооплачиваемые государственные служащие старались избегать демонстрации личного благосостояния. Для Сьюзан это не составляло проблемы: она была безмерно счастлива в своей скромной двухкомнатной квартире, водила вольво и довольствовалась весьма консервативным гардеробом. Но вот туфли - совсем другое. Даже во время учебы в колледже она старалась покупать самую лучшую обувь.
Глаза Бринкерхоффа чуть не вылезли из орбит. Мидж и раньше были свойственны фантазии, но ведь не. Он попробовал ее успокоить: - Джабба, похоже, совсем не волнуется.
