Latest Smog Stories
A Princeton study in 2004 found trees produce a volatile organic compound known as isoprene. But it wasn't until a recent study that the role of isoprene had been found to cause pollution via reaction from sunlight.
According the American Lung Association’s newly released State of the Air 2013 report, many people across the US are breathing higher quality air than in previous years. However, the number of people living in counties with an unhealthy level of air pollution has increased, the report said.
The association between road traffic and heart disease has been suggested in several studies.
Ever since the “ozone scare” that began in the 1970s, when it was reported that there was a hole in the ozone over the South Pole, there has been a great misunderstanding about ozone.
A new study from Columbia Engineering and the Georgia Institute of Technology shows – for the first time – certain volatile organic gases can promote cloud formation in ways atmospheric scientists have never before considered.
Thick smog in Beijing, China has left the city’s 20 million people with the worst air quality rating on its six-level scale. The city recommended its residents stay indoors, close windows and drink plenty of water as the air quality was reaching hazardous levels in the Chinese capital for the fifth straight day.
Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...
Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...
Haze is a type of atmospheric phenomenon where dust, smoke and dry particles in the air obscure the sky's clarity. Haze is created through various activities including farming, traffic pollution,and even wildfires. The World Meteorological Organization (WMO) categorizes the obscuration of the Earth's atmosphere by a list of different types of atmospheric phenomena. One of these is haze. The other classifications are: fog, ice fog, steam fog, mist, smoke, volcanic ash, dust, sand, and snow....
