How conditions affect cookies and air pollution control solutions

Chocolate chip cookies are one of my favorite treats. Butter, sugar, eggs, flour, vanilla, and, of course, chocolate chips. Combine the ingredients together and you get a delicious cookie. Somehow, using the same ingredients the cookies do not always turn out the same. Sometimes they are thinner and crispier. Other times, they are soft and chewy. After watching cooking shows, I have come to ...

History of Air Pollution in the UK

Introduction Concern about urban air quality is not new. Complaints were recorded in the 13th century when coal was first used in London. Since the middle of the 19th century, the atmosphere of the major British cities was regularly polluted by coal smoke in winter, giving rise to an infamous mixture of fog and smoke known as smog. Today the emphasis has shifted from the pollution ...

Inversions and air pollution in Istanbul

Owing to the rapidly growing and inefficient usage of fuel, air pollution has increased in Istanbul. The levels are affected by the weak dispersion conditions in the city. The strength of the inversion can be explained by the temperature difference between the top and bottom boundaries and their height. In this study, nighttime surface inversion heights have been found to range between 84 m and ...

Air pollution from ships

Emissions from shipping contribute significantly to the concentrations and fallout of harmful air pollutants in Europe. There are however technical means by which these pollutants could be cut by as much as 80-90 per cent, and very cost-effectively compared with what would have to be done to achieve similar results by taking further measures on land-based sources. Such reductions are needed for ...

Fireworks air pollution in Slovenia

Over the 'Christmas–New Year' period 12/2010–01/2011, PM10 air pollution measurements on most of the automatic measuring stations in Slovenia reached extreme values of up to 300 µg/m³. Analysis shows a very close correlation with the timings of the fireworks displays in the areas. This paper shows the other side of this cultural enjoyment - the effect on PM10 air pollution. As the correlation ...

Air pollution winter episode in Oslo

During 7 to 9 January 2003 the air pollution in Oslo reached record levels. The reason was that cold air was building up at the surface in the capital city of Norway. The cold air persisted for days while much warmer air was moving above the heavy cold air layer. On 8 January before noon a strong low temperature inversion at about 100 to150 masl was observed. This inversion completely blocked the ...

Synergistic effects of pollutants on air quality

The Pollutant Standards Index (PSI) was developed in the USA to give the public an overall assessment of the air quality on a regular basis. Currently, the PSI does not include the synergistic effects of the major air pollutants. Synergism applies when the damage caused by two or more pollutants, either to human health or property, is greater than the effect or damage caused by each individual ...

Air pollution and inversion features in Istanbul

Air pollution in the Istanbul metropolitan area arises from three significant sources: industrial and residential fossil fuels and road traffic. In winter this combination pushes air pollution to levels that are dangerous to humans and to plant life. As far as fossil fuels are concerned, total suspended particulates (TSP) and sulphur dioxide are the chief pollutants. In order to investigate the ...

Air pollution in Europe 1990-2004

Overall picture This report analyses and presents changes in air pollutant emissions and their possible health or ecosystem impacts in Europe covering the period 1990–2004. Emissions of all air pollutants fell substantially during the period 1990–2004 in the 32 EEA member countries (EEA-32), resulting in improved air quality over the region. However, ambient concentrations of particulate ...
