China Releases More Detailed Air Pollution Data
2012-01-22 05:53:50

For the first time on Saturday, Beijing officials released data disclosing the amount of minute particles polluting the air in what Reuters has called "of the world's most heavily polluted capitals." According to the Xinhua news agency, the Beijing Environment Protection Monitoring Center revealed that a monitoring station in the city detected 0.003 micrograms of fine particular matter of 2.5 micrometers or less in diameter (PM2.5), which equates to an air-quality rating of "good." The...

In a breakthrough paper published in this week's issue of Science magazine, researchers from Sandia's Combustion Research Facility, the University of Manchester and Bristol University report direct measurements of reactions of a gas-phase Criegee intermediate using photoionization mass spectrometry. (visit www.youtube.com/SandiaLabs to see a short video of Sandia combustion chemists discussing the research.) Criegee intermediates — carbonyl oxides — are implicated in...

A study conducted by researchers at Boston University School of Medicine (BUSM) has found that diesel exhaust particulates (DEP) and house dust extract (HDE) causes pulmonary inflammation that aggravates asthma. The study led by principle investigator Jiyoun Kim, PhD, professor of pathology, was published in the December issue of The American Journal of Pathology and was selected by the editorial board as the only article for an in-depth discussion in the journal's commentary section....

Researchers at the National Institute of Standards and Technology (NIST) spent 75 days on the job carrying out some very important homework–measurements in a "typical dwelling" of the release, distribution and fate of particles almost as tiny as the diameter of a single DNA molecule. Particles ranging in size from 100 nanometers down to 2.5 nanometers that were emitted by gas and electric stoves, hair dryers, power tools and candles were tracked and analyzed. Monitoring such tiny...

Image 1 - Aura Confirms Sharp Decline In US Pollution From Coal Power Plants
2011-12-02 04:48:03

A team of scientists have used the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite to confirm major reductions in the levels of a key air pollutant generated by coal power plants in the eastern United States. The pollutant, sulfur dioxide, contributes to the formation of acid rain and can cause serious health problems. The scientists, led by an Environment Canada researcher, have shown that sulfur dioxide levels in the vicinity of major coal power plants have fallen by nearly...

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....
