Establishing a more stringent ozone standard in the U.S. would significantly reduce ozone-related premature mortality and morbidity, according to a new study published online July 18 in the journal Environmental Health Perspectives. "Abundant evidence links exposure to ozone with adverse health effects, including impaired pulmonary function, asthma exacerbations, increased hospital and emergency room visits, and increased mortality, yet the current National Ambient Air Quality Standard of...
Bulk of Problem Takes Place at Natural Gas Plant Operations; Pattern of "Neglect" Seen As Pollution Sometimes Drags on for Weeks or Even Months. WASHINGTON, July 18, 2012 /PRNewswire-USNewswire/ -- "Accidents" and other non-routine events at Texas oil and gas facilities, refineries and petrochemical plants released almost 100,000 tons of pollution from 2009-2011, according to a new report from the Environmental Integrity Project (EIP) based on data gathered from a Texas Commission on...

UI researchers develop technique to help pollution forecasters see past clouds Until now, scientists who study air pollution using satellite imagery have been limited by weather. Clouds, in particular, provide much less information than a sunny day. University of Iowa scientists have created a technique to help satellites "see" through the clouds and better estimate the concentration of pollutants, such as soot. The finding is important, because, like GPS systems, clouds block...

Satellite measurements show that nitrogen dioxide in the lower atmosphere over parts of Europe and the US has fallen over the past decade. More than 15 years of atmospheric observations have revealed trends in air quality. As the world’s population increases, economies in many countries are also growing and populations are concentrating in large cities. With the use of fossil fuels still on the rise, pollution in large cities is also increasing. Nitrogen dioxide is an important...

Estimates capitalize on instrumental measurements of CO2 in smokestacks and pollutants in the air by satellites and surface stations Atmospheric scientists at the Harvard School of Engineering and Applied Sciences (SEAS) and Nanjing University have produced the first "bottom-up" estimates of China's carbon dioxide (CO2) emissions, for 2005 to 2009, and the first statistically rigorous estimates of the uncertainties surrounding China's CO2 emissions. The independent estimates, rooted in...

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...
