WASHINGTON, April 24, 2013 /PRNewswire-USNewswire/ -- The American Lung Association's "State of the Air 2013" report released today finds significant progress in the reduction of year-round particle pollution (soot) across the nation, but many cities that ranked among the most polluted had more unhealthy days of high ozone (smog) and short-term particle pollution than in the 2012 report. Despite that uptick, "State of the Air 2013" shows that the air quality nationwide continues the...

Results from large cohort study presented at EuroPRevent 2013 The association between road traffic and heart disease has been suggested in several studies. In 2012 a large prospective cohort study from Denmark showed that traffic noise was significantly associated with risk of heart attack - for every 10 decibel increase in noise exposure (either at the time of the attack or over the five years preceding it) there was a 12% increased risk. Now, a new study presented at the EuroPRevent...

A research team from Birkbeck, University of London, Royal Holloway University and Uppsala University in Sweden, have helped explain how ozone causes severe respiratory problems and thousands of cases of premature death each year by attacking the fatty lining of our lungs. In a study published in Langmuir, the team used neutrons from the Institut Laue-Langevin in Grenoble and the UK's ISIS Neutron Source to observe how even a relatively low dose of ozone attacks lipid molecules that line...

Coral Reefs Also Under Threat From Air Pollution
2013-04-08 04:30:56

redOrbit Staff & Wire Reports - Your Universe Online Fine particles in the air resulting from burning coal or volcanic eruptions can negatively affect coral growth, a team of climate scientists and coral ecologists from the UK, Australia and Panama has discovered. The study, which appears in this week´s edition of the journal Nature Geoscience, found that coral reefs respond to changes in the concentration of atmospheric pollution. Those particulates can shade the corals from...

Geostatistical Method Used To Predict Urban Pollution

FECYT - Spanish Foundation for Science and Technology Researchers from the University of Castilla-La Mancha have developed a measurement system which permits the prediction of atmospheric pollution due to nitrogen oxides in a specific location and at a particular time. The study is supported by a massive database from urban areas in the Community of Madrid. The World Health Organization has stated that almost 2.5 million people die every year from causes directly attributable to air...

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 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....

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...
