Trees Release Volatile Organic Compounds That Aid In Smog Production
2013-04-26 09:53:33

Brett Smith for redOrbit.com - Your Universe Online In 2004, a group of Princeton scientists found trees release the volatile organic compound (VOC) isoprene that reacts in the air to form particulate pollution, or smog. However, the mechanism behind this process wasn't known until a new study from scientists at the University of North Carolina (UNC) was released this week showing how isoprene´s reaction to sunlight leads to the formation of harmful air pollution. After isoprene...

American Lung Association Release State Of The Air 2013 Report
2013-04-25 05:11:21

Brett Smith for redOrbit.com - Your Universe Online According the American Lung Association´s newly released State of the Air 2013 report, many people across the US are breathing higher quality air than in previous years. However, the number of people living in counties with an unhealthy level of air pollution has increased, the report said. "The long-term trend is positive and headed to much cleaner air," report author Janice Nolen, assistant vice president of national policy and...

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...

Ozone Not Only Bad For Climate, But Also Bad For The Heart
2013-02-18 14:15:12

Peter Suciu for redOrbit.com — Your Universe Online Ever since the “ozone scare” that began in the 1970s, when it was reported that there was a hole in the ozone over the South Pole, there has been a great misunderstanding about ozone. In the past decade in fact it has only come out that ozone is actually not really good for people. Most recently researchers at Rice University in Houston have found a direct correlation between out-of-hospital cardiac arrests and levels...

Certain Volatile Gases Found To Promote Cloud Formation
2013-02-05 09:20:34

April Flowers for redOrbit.com - Your Universe Online A new study from Columbia Engineering and the Georgia Institute of Technology shows — for the first time — certain volatile organic gases can promote cloud formation in ways atmospheric scientists have never before considered. The findings of this study were published online in the Early Edition of the Proceedings of the National Academy of Sciences (PNAS). "This is the first time gases have been shown to affect cloud...

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....
