The preliminary results of a simulation of the air quality in a region of Northern Italy are presented. The simulation was performed using a modelling system based on a meteorological model, an interface code and a transport–chemistry model. Comparisons with measured data are presented and discussed.
Keywords: PM pollution, air quality, transport–chemistry modelling, dispersion modelling, particulate matter, simulation, air pollution
There are many types of air quality monitors available, but which one is the best choice for measuring gaseous air pollutant concentrations? There are two classes of such air quality monitors: sampling monitors and in-situ monitors (“in-situ” = “in the original position”). Sampling monitors utilises a manifold through which the air to be analysed is pumped. A small air sample is then enclosed in a cell where its molecular content can be analysed. The analysis method varies depending on...
A study connects days with high levels of pollution with myocardial infarctionMore several myocardial infarction happens when pollution levels are higher. A study of cardiologists from Vall d’Hebron demonstrate it Tobacco use, alcoholism, sedentariness, unhealthy diet… The usual bad habits that provoques plaque build-up in the coronary arteries have a new ally, for the first time, pollution is considered a heart attack cause. The conclusion of the study is clear: In days with more pollution of PM 10...
India’s dirty secret has a silver lining: The air pollution that is affecting millions of people in the country’s traffic-jammed cities can be turned into creative human expression with the help of a clever invention.A team of four young scientists have developed a special device that collects carbon soot from engine exhaust. They then turn the collected particulate matter into different kinds of ink and paint, which they named AIR-INK.One of their ink-filled pens, for example, can be filled with the...
“Under the Dome" showcases huge problem in China The “fog” blanketing China most days used to be thought of as a natural weather phenomenon that couldn’t be helped. But since 2012, the words “smog”, “PM2.5”, “air pollution” and “fine particles” have become analogous to a nation’s struggle against an invisible enemy threatening the public health. For television journalist Chai Jing, her eye-opening moment came when her unborn daughter...
You know you have a problem when the smog gets so bad even airplanes can’t land safely anymore. This is what happened last month, when an airplane coming from Japan had close to zero visibility as it was trying to land in Beijing. There was thick smog blanketing the city. It was so bad that the plane requested permission to land at two alternative airports. However, permission was initially denied and the plane was forced to keep circling in the air. After what must have felt like hours, the plane was...
