In May 2010, the ash cloud from the Icelandic volcano Eyjafjallajökull reached the Iberian Peninsula and brought airports to a halt all over Europe. At the time, scientists followed its paths using satellites, laser detectors, sun photometers and other instruments. Two years later they have now presented the results and models that will help to prevent the consequences of such natural phenomena. The eruption of the Eyjafjallajökull in the south of Iceland began on the 20 March, 2010. On...

Beth Israel Deaconess Medical Center study focuses on pollution threat Living close to a major highway poses a significant risk to heart attack survivors, reinforcing the need to isolate housing developments from heavy traffic areas, a Beth Israel Deaconess Medical Center study concludes. Writing in the May 7 edition of Circulation, researchers found heart attack survivors living less than 100 meters or 328 feet from a roadway have a 27 percent higher risk of over within 10 years than...
Heart attack survivors who live about 100 meters (328 feet) or less from a major U.S. roadway face increased risk of death from all causes, according to new research in the American Heart Association's journal Circulation. In the Determinants of MI Onset Study of 3,547 heart attack survivors (average age 62), researchers found: Those living less than 100 meters (328 feet) from the roadway have a 27 percent increased risks of dying over 10 years than those living at least 1,000 meters...
UD's long-term monitoring shows 60 percent reduction in acidity of Delaware rain Several decades ago, precipitation in Delaware was among the most acidic in the country. Pollutants in the air reacted with rainwater to sprinkle sulfuric, nitric and carbonic acids onto the ground below, affecting crops and ecosystems statewide. The scientific consensus is that pollution controls enacted through the Clean Air Act Amendments in the 1990s and other measures have helped decrease the acidity...

A gas mask is designed to go over the face to protect the wearer from inhaling "airborne pollutants". The mask seals the nose and mouth and many times covers other soft tissues of the face. Some have respirators. Most gas masks provide protection from gaseous and particulate and are often used by riot police and rioters alike. They are also used by graffiti artists to protect them from the fumes. The original design had two small glass eye windows that were thick in order from keeping the...
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...
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....
Mist is a phenomenon that consists of small droplets of water suspended in air. Mist occurs as part of a natural weather event or from volcanic activity. Mist is most common in cold air above warm water. Mist also occurs when air is exhaled in cold temperatures or when steam is formed in a sauna. Aerosol cans can create artificial mist if the humidity levels are just right. The one difference between mist and fog is visibility. If visibility is less than 0.62 miles (1 kilometer), the...
