Wyoming is looking more like Los Angeles because of the recent boom in natural gas drilling, reports The Associated Press (AP). People are now complaining of watery eyes, shortness of breath and bloody noses because of ozone levels that have exceeded what people in L.A. and other major cities deal with. In the Upper Green River Basin, some wonder if they have made a bargain with the devil by having gas drilling go strong again.  Because of this, Wyoming enjoys one of the nation's...

Differences in air pressure over the North Atlantic have meant that the last two winters in Gothenburg, Sweden, have been extremely cold. This has led to the air in Gothenburg being more polluted with nitrogen oxides than ever before. A new study from the University of Gothenburg shows that there is a strong link between climate and air pollution. The winter weather in Gothenburg and large parts of North-West Europe is partly down to the North Atlantic Oscillation (NAO), in other words the...

An independent assessment of air pollution in China by the US embassy showed that the thick smog covering Beijing went "beyond" measurable levels on Monday, as a Chinese official warned its citizens to avoid outdoor activities. The assessment said that the pollution was either hazardous or "beyond index," meaning that air quality had plunged below the worst level on the scale. Air quality in a majority of the city was at level five, -- the worst possible rating -- according to the Beijing...

Voters trust EPA to protect public health, oppose Congressional interference WASHINGTON, Feb. 16, 2011 /PRNewswire-USNewswire/ -- Just one day before the U.S. House of Representatives votes on a bill that would severely impact the U.S. Environmental Protection Agency's (EPA) ability to protect public health from air pollution, the American Lung Association has released a new bipartisan survey examining public views of EPA's updating and enforcing clean air standards. The bipartisan...

Scientists have developed electronic "noses" in order to help assist in search and rescue. Professor Paul Thomas is head of the research group at Loughborough University's Center for Analytical Science, which have designed the device to be placed in the environment of a collapsed building. The device contains a sensitive microphone, an infra-red detector, and a sophisticated chemical "nose" in the form of an ion mobility spectrometer. It contains various sensors that will collect and combine...

Certain types of pollution monitoring may soon become considerably easier. A group of researchers centered at Kyoto University has shown in a recent Nature Communications paper that a newly-formulated entangled framework of porous crystals (porous coordination polymers, or PCPs) can not only capture a variety of common air pollutants, but that the mixtures then glow in specific, easily-detected colors. Lead author for the paper was Dr. Yohei Takashima. Until now, chemical sensors have...

Acid Rain
2013-04-01 10:21:17

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....
