analyses identified old carbonin the Yukon River

While studying climate change and trying to decipher the carbon cycle puzzle, researchers have been studying the source and amount of carbon flowing into the Arctic Ocean. Organic carbon has been found on glaciers in Alaska and when organic matter and other materials from the atmosphere are deposited on the surface of a glacier, the […]

NADP sites where USGS measured 137Cs in precipitation samples

A nationwide study released today showed that fallout from the 2011 Fukushima Dai-ichi nuclear power facility in Japan was measured in minimal amounts in precipitation in the United States. Data was collected at monitoring sites within the NADP network and detections were most frequently found along the West Coast, in the central and northern Rocky […]

Location of wells sampled for the study and radium concentrations

In a recent study, radium was measured in untreated source water in wells from aquifers that are used for public and domestic water supply. This is the first nationwide study to identify factors that make an aquifer susceptible to radium contamination and researchers found that radium levels are determined by the chemical attributes of the […]

A professional applicator applies coal-tar-based sealcoat to a test plot used to measure emission of polycyclic aromatic carbons (PAHs) into the air

According to several newly published reports by the U.S. Geological Survey, coal-tar-based sealants are emitting polycyclic aromatic hydrocarbons (PAHs) into the air at rates possibly greater than annual emissions from automobiles in the US. Four new reports examine the contaminants polycyclic aromatic hydrocarbons (PAHs) found in house dust, streams, lakes, soil, and air. Coal-tar-based sealants […]

Gas hydrate deposits by sector.

Recent research indicates that gas hydrate deposits should remain stable for a few thousand years and of those that become unstable, very few are likely to end up in the atmosphere contributing to global warming. This news comes from the U.S. Geological Survey and their researchers that have been examining the link between climate change […]

National Acid Precipitation Assessment Program Reports Decreases in Acid Rain

The National Acid Precipitation Assessment Program stated a decrease in acid rain in a report that was presented to Congress. The report states that sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions have continued to decline and are lower than the 2009 levels. Sulfur dioxide and nitrogen oxides in the atmosphere are the primary causes […]
