In the first effort to estimate the overall impact of a city’s urban forest on concentrations of fine particulate pollution (particulate matter less than 2.5 microns, or PM2.5), a U.S. Forest Service and Davey Institute study found that urban trees and forests are saving an average of one life every year per city.
Taking part in the largest U.S. air quality field project in decades, the National Center for Atmospheric Research is working with partners to study pollution in the Southeast.
Jell Chemicals offers a no fee analysis of any chemical blend of interest with the intent of producing a functionally equivalent chemical blend with lower VOCs and better compliance with relevant

A new study on cloud formation shows that climate change models may have underestimated the cooling effect of sulfur aerosol particles in the atmosphere.
Experts reveal important disaster preparedness tips and strategies to specifically help protect small businesses before natural or man-made disasters occur.
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....
