Trees may be guilty for trapping pollution in cities, a new report says. The study was done in the UK and aimed to outline how government can reduce toxic fumes and reduce their effect on public health. The scientists say that trees trap pollutants and keep them at the street level. However, a number of […]

Urban pollution caused by nitrogen oxides can now be predicted for specific locations at particular hours, thanks to recent study done by scientists at the University of Castilla-La Mancha (UCLM). The researchers developed a geostatistical method that takes into account the space-time factor, something that had not been considered before. The method, called functional krigging, […]

Green walls have been acknowledged as one of the most effective ways to cut down city air pollution, improve building’s energy efficiency, reduce noise and at the same time give a warm green feel to the usually colorless city architecture. Imagine walking on the streets of a major city like Paris, battling your way through […]

A new finding from Dr. Thomas Pugh, at the Karlsruhe Institute of Technology (KIT) in Germany, reveals the fact that city vegetation does more good than thought before. “Green areas may be grown road by road without expensive or big initiatives,” says Pugh. He also says that green plants filter nitrogen oxide (NO2) and fine […]

Wind-Carried Pollutant Particles Concentrate In Unexpected Patterns in Cities

Ovidiu Sandru — Fri, 24 Aug 2012 15:18:01 +0000

Pollutant particles prefer to accumulate in specific regions in cities and form coherent structures, a team of researchers at the Arizona State University in Tempe found. The findings have been published recently in the American Institute of Physics. Wenbo Tang from ASU said their discoveries were unexpected: “The unexpected finding is coherent patterns in fluid flows were […]

A recent study performed by two Finnish researchers from Aalto University reveals that people living in the countryside pollute just as much as city dwellers. They used a different approach to fund their study's conclusion, placing the source of CO2 at the consumer site rather than at the production site, like it's been done before.
