New Article Published: ECO PHYSICS CLD 899 Y Used for Measurement of Ambient Air Pollution
NOx: Traffic Dramatically Underestimated as Major Polluter Traffic contributes more to nitrogen oxide emissions in Europe than previously thought. This is the result of a current study carried out by scientists from the University of Innsbruck. The research team headed by Thomas Karl shows that even newer air quality models underestimate traffic related nitrogen oxide pollution by up to a factor ...

Modelling marine exhaust emissions in the Baltic Sea
A new tool used to investigate exhaust emissions of marine vessels has been developed and applied to shipping in the Baltic Sea. The Baltic Sea is a busy maritime region with 3500-5000 ships operating in the area every month. Emissions from shipping contribute significantly to atmospheric pollution, leading to health and environmental problems. In May 2006, the Baltic Sea was the first area ...

EPA seeks to adopt emission standards for large commercial aircraft
The U.S. Environmental Protection Agency (EPA) is proposing to adopt new air pollution standards for engines used primarily in large commercial aircraft, including 737s, 747s, and 767s. The proposal would reduce ground-level nitrogen oxide emissions by an estimated 100,000 tons nationwide by 2030. Exposure to nitrogen oxide emissions can cause and aggravate lung diseases and increase ...

China exports air pollution to the North America’s West Coast
Many of the measures taken by federal, state and local administrations in the United States to improve air quality on its West Coast are being thwarted by air pollution blowing across from China. This is the conclusion of research conducted by Wageningen University in association with the Royal Netherlands Meteorological Institute (KNMI) and the American space agency NASA, recently published in ...

CTP’s new solution for a combined cleaning of organic pollutants and nitrogen oxides: RTO-i-SCR
Lanxess, the specialty chemicals company, has taken another major step on the road to climate neutrality. The new nitrous oxide reduction plant breaks down around 500 metric tons of nitrous oxide per year, which is equivalent to the climate impact of 150,000 metric tons of CO2. Nitrous oxide (N2O), also known as laughing gas, is generated at the Antwerp site during the production of the ...

Evaluating the impact of air quality measures is essential
Recent research has investigated the effectiveness of air quality management at the regional level in Italy and found that some of the most commonly adopted measures do not always produce the highest emissions reductions. Italian air quality legislation was reformed in 1999 in order to comply with the 1996 European Air Quality Framework Directive1. At the time, the 20 Italian administrative ...
