How often do we hear warnings for people with respiratory conditions to stay inside to avoid high levels of poor or toxic air in their communities? There are good reasons for those warnings. The U.S. Environmental Protection Agency (EPA) sees how damaging these sky-high air pollutant levels can be and, as a result, are focusing more closely on urban air quality (more…)
Los Angeles is known not only for its celebrity clientele, but also for its congested roadways and heavy traffic, which consequently has led to severely polluted air, and the title of the “smoggiest city” in the United States. While air quality has improved somewhat in LA, a joint study by UCLA and the California Air Resources Board suggests that nearly a quarter of Angelenos (more…)
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…)
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…)
Levels of some automobile-related pollutants in Los Angeles have plummeted by 98 percent since the 1960s, even as gasoline consumption nearly tripled during the same period, a new study says.
Levels of volatile organic compounds (VOCs), which are emitted from the tailpipes of cars and are a key (more…)
There is deep concern over air quality in China especially during the 2008 Olympics held there. Concern was raised over the air quality, and its potential effect on the athletes. Beijing committed then to remove 60,000 taxis and buses from the roads by the end of 2007 and relocate 200 local factories, including a prominent steel factory, China’s Olympian attempt (more…)
