Air Pollutant Optimization Model Helps Reduce Health Impact of Ozone and Fine Particulate Pollution

By combining information about power plant operation with real-time air quality predictions, researchers have created a new capability to minimize the human health effects of air pollution resulting from electric power generating facilities.

Asia Produces More Than Double the Mercury Emissions Previously Estimated

Once mercury is emitted into the atmosphere from the smokestacks of power plants, the pollutant has a complicated trajectory; even after it settles onto land and sinks into oceans, mercury can be re-emitted back into the atmosphere repeatedly. This so-called “grasshopper effect” keeps the highly toxic substance circulating as “legacy emissions” that, combined with new smokestack emissions, can extend the environmental effects of mercury for decades.

Study Shows Industrial Fires in Indonesia Make the Biggest Contributions to Air Pollution

Researchers have combined satellite observations with atmospheric modelling to calculate how fires associated with industrial concessions in the Sumatra and Kalimantan regions of Indonesia affect air quality across Equatorial Asia.

Natural Factors, Chinese Air Pollution Undermine Ozone Gains in Western United States

A new study finds that the western United States reduced its production of ozone-forming pollutants by a whopping 21 percent between 2005 and 2010, but ozone in the atmosphere above the region did not drop as expected in response. The reason: a combination of naturally occurring atmospheric processes and pollutants crossing the Pacific Ocean from China.

Lack of Baseline Data Challenge Evaluation of Environmental Impacts of 2010 Deepwater Horizon Blowout

In the spring of 2010, the Deepwater Horizon drilling platform exploded, initiating an uncontrolled deep-water oil and gas blowout from the Macondo wellhead. The uncontrolled hydrocarbon discharge continued for 85 days and the environmental impacts were substantial.

Adult Corals Exposed to Ocean Acidification May Help Offspring Adjust to Future Climate Change

A new study from scientists at the University of Hawai'i - Mânoa's (UHM) Hawai'i Institute of Marine Biology (HIMB) reveals that preconditioning adult corals to increased temperature and ocean acidification resulted in offspring that may be better able to handle those future environmental stressors. This rapid trans-generational acclimatization may be able to "buy time" for corals in the race against climate change.

CU-Boulder's Innovative Microbial Electrolytic Carbon Capture Process Purifies Wastewater in Eco-Friendly Manner

Cleaning up municipal and industrial wastewater can be dirty business, but engineers at the University of Colorado Boulder have developed an innovative wastewater treatment process that not only mitigates carbon dioxide (CO2) emissions, but actively captures greenhouse gases as well.

Continuing CO2 Emission Trends Would Leave Legacy of Heat and Acidity in Deep Ocean

Continuing current carbon dioxide (CO2) emission trends throughout this century and beyond would leave a legacy of heat and acidity in the deep ocean. These changes would linger even if the atmospheric carbon dioxide concentration were to be restored to pre-industrial levels at some point in the future, according to a new Nature Climate Change paper from an international team including Carnegie’s Ken Caldeira. This is due to the tremendous inertia of the ocean system.

Test Evaluates Efficiency of Ozonation for Enhanced Wastewater Treatment

Ozone treatment efficiently removes many micropollutants contained in wastewater, but in some cases, it can lead to the formation of toxic byproducts. A new test informs on whether ozonation is a suitable technology for enhanced wastewater treatment.

Soot Pollution on Himalayan-Tibetan Plateau Contributes to Earlier Snowmelt , Shrinking Glaciers

Using a climate model that can tag sources of soot from different global regions and can track where it lands on the Tibetan Plateau, researchers have determined which areas around the plateau contribute the most soot -- and where. The model can also suggest the most effective way to reduce soot on the plateau, easing the amount of warming the region undergoes.
