New satellite data released by NASA provide dramatic visual evidence of the dangerous air quality reported from cities across Asia and the Middle East this month.
NASA’s Terra satellite acquired natural-color images of northeastern China on January 3 and January 14, highlighting a drastic shift in air quality for the region.
According to the images, the opaque, gray areas are clouds or fog, which are saturated with a gray or yellow tint as a result from the air pollution. (more…)
Researchers at the University of California, San Diego have developed a network of smartphone-based air pollution monitors that allow individuals to track pollution levels in real time and feed a central database of air quality trends citywide throughout the day.
The so-called CitySense devices are equipped with sensors that measure ozone, nitrogen dioxide, and (more…)
NOx is a pollutant that comes from all combustion emissions. It can be minimized but not eliminated at the stack. Painted surfaces (a very common urban surface area) with photo-catalytic characteristics may be able to clean the air of nitrogen oxides and other health-endangering substances. Using a new testing procedure, Fraunhofer researchers can find out how (more…)
A team of Israeli researchers has developed a method to track pollution over the world’s mega-cities, a satellite-based process they say could help hold nations accountable for their pollution and promote cleaner industrial practices.
Using data collected by three NASA satellite systems, the researchers from Tel Aviv University (more…)
Putting a speed limit on cargo ships as they sail near ports and coastlines could cut their emission of air pollutants by up to 70 percent, reducing the impact of marine shipping on Earth’s climate and human health, scientists have found. Their evaluation of the impact of vessel speed reduction policies, such as those proposed by the California Air Resources Board, (more…)
Deep-sea cameras deployed to monitor biodiversity on the Arctic seabed have documented a significant rise in the amount of plastic waste and other litter on the remote sea floors of the Far North, according to a new study.
While looking at many thousands of seabed photos (more…)
There are many ways to harm your respiratory system such as smoking or breathing in asbestos. For urbanites living in cities across Europe, merely living and breathing in the city can be bad. A new study released by the European Environment Agency (EEA) found that most residents of European cities breathe toxic pollutants exceeding international health standards. The most (more…)
