Air pollution analyzer

In preparation for the 2012 Olympics in London, UK, scientists have tested the analyzer to determine the location of air pollution due to the flow of people to the city during the Olympic Games. Assembly.

The new scanner will help professionals build the city's air pollution map during the 2012 Olympics.

Leicester University researchers have experimented with scanners installed on rooftops in London to create a 3D pollution map of the city.

The machine was named CityScan , which uses sunlight to determine the pollution of nitrogen dioxide (NO 2 ) shown on the urban environmental map.

The head of the research team is Dr. Roland Leigh, of the University of Leicester, told The Engineer: 'CityScan uses sunlight absorbing structures to establish separate lines that can observe pollution levels.'

CityScan is different from existing scanners, which help us to accurately read 'hotspots' on 3D maps. It can display all of the points in London, which point to the homes, corners, gardens of each family and large buildings. From there, CityScan paints the fullest panorama of air quality. More specifically, thanks to the sensors, they will tell the specific time of the pollution.

The machine will be located at three points on the roof of a 30-storey building in North Kensington, a 14-storey building in Chelsea and a third.

The sensor is very sensitive to NO2 in the atmosphere, emitted from automobile exhaust, harmful to the health of humans, such as reduced lung function and cause respiratory diseases such as bronchitis, asthma .

The 2012 Olympics and Paralympic Games could attract 11 million visitors from across the planet to London for seven weeks, beginning on July 27, and around three million trips throughout the day. on the street.

This is a means to help reduce pollution and optimize traffic in London during the Olympics.

"Due to the increase in activities, air quality in London will, of course, be worse than usual, so there are measures to mitigate its impact. This is a challenge, and measuring the level of pollution at every angle will help us significantly improve the Olympic Games , "Leigh said.
