Smog can form in almost any

For the past few years, cities in northern India have been covered in a thick layer of winter smog. The situation has turned quite drastic in the National Capital, Delhi. This smog is caused by the collection of Particulate Matter a very fine type of dust and toxic gases in the air due to stagnant movement of air during winters.

Volatile organic compounds A primary pollutant is an air pollutant emitted directly from a source. A secondary pollutant is not directly emitted as such, but forms when other pollutants primary pollutants react in the atmosphere.

Examples of a secondary pollutant include ozone, which is formed when hydrocarbons HC and nitrogen oxides NO combine in the presence of sunlight; nitrogen dioxide NOwhich is formed as nitric oxide NO combines with oxygen in the air; and acid rain, which is formed when sulfur dioxide or nitrogen oxides react with water.

Photochemical smog is therefore considered to be a problem of modern industrialization. It is Smog can form in almost any in all modern cities, but it is more common in cities with sunny, warm, dry climates and a large number of motor vehicles.

The composition and chemical reactions involved in photochemical smog were not understood until the s. Inflavor chemist Arie Haagen-Smit adapted some of his equipment to collect chemicals from polluted air, and identified ozone as a component of Los Angeles smog.

Haagen-Smit went on to discover that nitrous oxides from automotive exhausts and gaseous hydrocarbons from cars and oil refineries, exposed to sunlight, were key ingredients in the formation of ozone and photochemical smog.

The brown coloration is due to the NO in the photochemical smog. Natural causes An erupting volcano can also emit high levels of sulfur dioxide along with a large quantity of particulate matter; two key components to the creation of smog.

However, the smog created as a result of a volcanic eruption is often known as vog to distinguish it as a natural occurrence. The radiocarbon content of some plant life has been linked to the distribution of smog in some areas.

For example, the creosote bush in the Los Angeles area has been shown to have an effect on smog distribution that is more than fossil fuel combustion alone.

Hospital admissions and respiratory deaths often increase during periods when ozone levels are high. An experiment was carried out using intense air pollution similar to that of the Great Smog of London.

The results from this experiment concluded that there is a link between early-life pollution exposure that leads to the development of asthma, Proposing the ongoing effect of the Great Smog. One study, published in Nature magazinefound that smog episodes in the city of Jinan, a large city in eastern China, during —15, were associated with a 5.

This study highlights the effect of exposure to air pollution on the rate of mortality in China. Researchers at Lancaster University found abundant magnetite nanoparticles in the brain tissue from 37 individuals aged three to years-old who lived in Mexico City and Manchester. However, it is worse during periods of warmer, sunnier weather when the upper air is warm enough to inhibit vertical circulation.

It is especially prevalent in geologic basins encircled by hills or mountains. It often stays for an extended period of time over densely populated cities or urban areas, and can build up to dangerous levels.

Canada According to the Canadian Science Smog Assessment published insmog is responsible for detrimental effects on human and ecosystem health, as well as socioeconomic well-being across the country.

Air pollution in British Columbia is of particular concern, especially in the Fraser Valley, because of a meteorological effect called inversion which decreases air dispersion and leads to smog concentration.

For the past few years, cities in northern India have been covered in a thick layer of winter smog. The situation has turned quite drastic in the National Capital, Delhi. This smog is caused by the collection of Particulate Matter a very fine type of dust and toxic gases in the air due to stagnant movement of air during winters.

United Kingdom London Victorian London was notorious for its thick smogs, or " pea-soupers ", a fact that is often recreated as here to add an air of mystery to a period costume drama Inconcerns over air pollution were sufficient for Edward I to briefly ban coal fires in London.

The " Ballad of Gresham College " the same year describes how the smoke "does our lungs and spirits choke, Our hanging spoil, and rust our iron. Initially a flu epidemic was blamed for the loss of life.

In the Clean Air Act started legally enforcing smokeless zones in the capital. There were areas where no soft coal was allowed to be burned in homes or in businesses, only cokewhich produces no smoke. Because of the smokeless zones, reduced levels of sooty particulates eliminated the intense and persistent London smog.

It was after this that the great clean-up of London began.

One by one, historical buildings which, during the previous two centuries had gradually completely blackened externally, had their stone facades cleaned and restored to their original appearance. Victorian buildings whose appearance changed dramatically after cleaning included the British Museum of Natural History.Smog can form in almost any climate where industries or cities release large amounts of air pollution.

Summer can bring more than just sunshine and swimming opportunities. In many urban areas, summer is the time of year when smog is at its worst. Smog is a form of air pollution that’s. Smog can form in almost any climate where industries or cities release large amounts of air pollution.

However, it is worse during periods of warmer, sunnier weather when the upper air is warm enough to inhibit vertical circulation. It is especially prevalent in geologic basins encircled by hills or mountains. Smog is a common form of air pollution found mainly in urban areas and large population centers.

The term refers to any type of atmospheric pollution—regardless of source, composition, or concentration—that creates a significant reduction in atmospheric visibility. Almost Any Ability (AAA) is an Other Metagame based on OU with one simple change: Pokémon can now use almost any ability!

That means that you can give your Lucario Refrigerate or your Tapu Fini Poison Heal. Smog reminds me of my junior high school days when there was a buzz about impact of smog on environment and health of people. The word Smog comes from the blend of two words -smoke and fog.

It can form in almost any climate where industries or cities release large .
