Pollution

Next ten years critical for achieving climate change goals
April 13, 2017 09:08 AM - International Institute for Applied Systems Analysis

In order to have a good chance of meeting the limits set by the Paris Agreement, it will be necessary to both reduce greenhouse gas emissions while preserving carbon sinks,  with net emissions peaking in the next ten years, according to a new study.

Melting snow contains a toxic cocktail of pollutants
April 11, 2017 11:17 AM - McGill University

With spring finally here and warmer temperatures just around the corner, snow will slowly melt away, releasing us from the clutches of winter. However, that’s not the only thing that the melting snow will release. Researchers from McGill University and École de technologie supérieure in Montreal have found that urban snow accumulates a toxic cocktail from car emissions - pollutants that are in turn unleashed into the environment as the weather warms up.

Satellites map carbon sequestered by forests, with accuracy of up to ten metres
April 7, 2017 09:40 AM - VTT Technical Research Centre of Finland

Led by VTT, the EU North State project has developed a new method of using satellite images to evaluate the forest carbon balance. The carbon balance indicates how much carbon is sequestered or released by forests each year. This enables the carbon balance to be displayed on digital maps, with an accuracy of up to ten metres.

Consumer behaviour causing premature deaths from air pollution
April 7, 2017 08:15 AM - University of British Columbia (UBC)

A UBC researcher is drawing attention to the human cost of our consumer behaviour by examining the number of deaths caused by air pollution from manufacturing goods. While some countries bear the brunt of the health risks from air pollution, the products often end up in the hands of consumers in other countries.

Potentially Explosive Methane Gas Mobile in Groundwater, Poses Safety Risk: Study
April 5, 2017 11:48 AM - University of Guelph

Potentially explosive methane gas leaking from energy wells may travel extensively through groundwater and pose a safety risk, according to a new study by University of Guelph researchers.

Nitrogen, phosphorus from fertilizers and pet waste polluting urban water

New research from the University of Minnesota points to lawn fertilizers and pet waste as the dominant sources of nitrogen and phosphorus pollutants in seven sub-watersheds of the Mississippi River in Saint Paul, Minnesota.

First-of-its-kind Interactive Map Brings Together 40 Years of Water-Quality Data
April 5, 2017 08:15 AM - United States Geological Survey (USGS)

A new U.S. Geological Survey interactive map provides a comprehensive, long-term look at changes in the quality of our nation’s rivers and streams over the last four decades. For the first time, monitoring data collected by the USGS and 73 other organizations at almost 1,400 sites have been combined to provide a nationwide look at changes in the quality of our rivers and streams between the 1972 passage of the Clean Water Act and 2012.

Exploring ocean waters to characterize atmospheric aerosols
April 3, 2017 11:00 AM - University of Geneva

Aerosols are collections of fine particles, either biological or of other types, in suspension in a gaseous medium. They play a major role in cloud formation and therefore have a strong impact on climate models. They are however extremely hard to study due to the small size and immense variety of their constituent particles. But researchers from the University of Geneva (UNIGE), Switzerland, members of the PlanetSolar Deepwater expedition, have now succeeded in linking the composition of marine biological aerosols - and therefore their influence on the climate - to that of bodies of water under them within the Atlantic Ocean, thereby paving the way to an indirect study of these aerosols through water analysis. This study, which has been published in Scientific Reports, will contribute to making climate models more accurate.
