Honey Bees' Ability To Locate Food Masked By Diesel Fumes
2013-10-03 12:53:25

[ Watch the Video: Honeybees Impacted By Diesel Exhaust ] Brett Smith for redOrbit.com - Your Universe Online Scientists are currently in search of an explanation for the decline of honeybee populations around the world and a new study published in the journal Scientific Reports has found that diesel exhaust may be playing a role. In the study, researchers from the University of Southampton found that diesel exhaust fumes change the chemical profile of floral aroma molecules, a...

NASA Study Finds Connection Between Population And Pollution
2013-08-20 14:33:41

Brett Smith for redOrbit.com - Your Universe Online While previous research has linked employment or innovation statistics to urban population density, a new study from NASA scientists has made a connection between pollution and the number of people living in a city. Using satellite observations, the NASA team was able to calculate air pollution's dependence on population for cities in the United States, Europe, China and India. According to the report, which was published in the...

“Keeping It Clean: Our Air, Our Health” addressed ground-level ozone, public health and economic development. San Antonio, TX (PRWEB) July 18, 2013 Stakeholders across multiple disciplines met on July 11 to raise awareness of air quality concerns as the Alamo City edges closer to EPA “non-attainment” with increased ground level ozone levels (a.k.a. “smog”) from an economic boom in one of the fastest-growing metro areas. Held at Rackspace’s global headquarters, the Keeping...

Air Pollution Takes Two Million Lives Each Year
2013-07-12 12:35:01

Lee Rannals for redOrbit.com - Your Universe Online According to a study published in the journal Environmental Research Letters, over two million people die every year as a result of air pollution. Researchers have shown that around 2.1 million deaths are caused each year by a human-caused increase in fine particulate matter (PM2.5). These are tiny particles suspended in the air that can penetrate deep into the lungs, causing cancer and other respiratory diseases. The team also found...

New quasi-experimental research finds major impact of coal emissions on health A high level of air pollution, in the form of particulates produced by burning coal, significantly shortens the lives of people exposed to it, according to a unique new study of China co-authored by an MIT economist. The research is based on long-term data compiled for the first time, and projects that the 500 million Chinese who live north of the Huai River are set to lose an aggregate 2.5 billion years of...

High Nitrogen Dioxide Levels From Three Large Fires In Arizona
2013-07-02 17:24:56

NASA This June 29, 2013 image from the OMI, or Ozone Monitoring Instrument aboard NASA's Aura satellite shows nitrogen dioxide (NO2) levels in Arizona pertaining to three large fires. The highest levels of NO2, which is produced by combustion, were from the Yarnell Hill fire (dark red and brown). NO2 concentration is given as the number of molecules in a cubic centimeter. The highest NO2 concentration values (8-9 x 10^15) indicated that this strong fire was burning a large amount of...

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....
