  • A battery-inspired strategy for carbon fixation
    on August 9, 2017 at 6:03 pm

    Scientists working toward the elusive lithium-air battery discovered an unexpected approach to capturing and storing carbon dioxide away from the atmosphere. Using a design intended for a lithium-CO2 battery, researchers have developed a way to isolate solid carbon dust from gaseous carbon dioxide, with the potential to also separate out oxygen gas through the same method. […]

  • Biochar shows benefits as manure lagoon cover
    on August 9, 2017 at 6:02 pm

    Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few. New methods may reduce these negatives while potentially adding some positives: biochar covers. […]

  • Benefits of advanced wood-burning stoves greater than thought
    on August 7, 2017 at 3:28 pm

    Advanced wood-burning stoves designed for use in the developing world can reduce air pollution more than anticipated, because gaseous emissions from traditional wood stoves form more particulate matter in the atmosphere than researchers previously thought. […]

  • In utero exposure to diesel exhaust could be linked to adult heart failure
    on August 7, 2017 at 3:03 pm

    Gestational exposure to airborne particles derived from diesel exhaust can modify DNA in utero and alter the expression of genes that potentially increase susceptibility to adult heart failure, suggests a study in mice. […]

  • Where there's fire, there's smoke -- and social media
    on August 3, 2017 at 12:12 am

    The fact that people reliably flock to social media to discuss smoke and fire was the inspiration for a new study by atmospheric scientists. The researchers showed striking correlation between numbers of Facebook users posting about visible smoke, and commonly used datasets for estimating harmful smoke exposure. These include satellite observations, chemical transport models and surface particulate matter measurements. […]

  • Wildfires continue to beleaguer Western Canada
    on August 1, 2017 at 3:52 pm

    Like tourist season, wildfire season is also in full swing in British Columbia. Whereas tourists are welcomed to the Canadian province, wildfires are not. In British Columbia alone there are close to 500 wildfires active to date. […]

  • Climate change expected to increase premature deaths from air pollution
    on July 31, 2017 at 3:45 pm

    Future climate change, if left unaddressed, is expected to cause roughly 60,000 deaths globally in the year 2030 and 260,000 deaths in 2100 due to climate change's effect on global air pollution, a new study estimates.  &nbs […]

  • Biochar could clear the air in more ways than one
    on July 27, 2017 at 2:29 pm

    Biochar could reduce local air pollution from agriculture by reducing emissions of nitric oxide from soil. Researchers argue that a better understanding of nitric oxide response to biochar will save lives and money, especially on farms near urban areas where agricultural emissions contribute to ozone and particulate matter formation. […]

  • Ozone pollution connected to cardiovascular health
    on July 17, 2017 at 3:05 pm

    Exposure to ozone, a risk for impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. A new study followed 89 healthy adults living in Changsha City for one year. They showed blood platelet activation and an increase in blood pressure, suggesting a possible mechanism by which ozone may affect cardiovascular health. […]

  • Tiny particles increase in air with ethanol-to-gasoline switch
    on July 17, 2017 at 1:10 pm

    The concentration of ultrafine particles less than 50 nanometers in diameter rose by one-third in the air of São Paulo, Brazil, when higher ethanol prices induced drivers to switch from ethanol to gasoline, according to a new study. The research team also found when drivers switched back to ethanol because prices had gone down, the concentration of ultrafine particles also went down. […]

  • Costs of coal storage and its impact on disadvantaged communities
    on July 5, 2017 at 5:30 pm

    While the negative health and environmental effects of mining and burning coal are well documented, simply transporting and storing coal can also adversely affect the health outcomes of individuals living near coal-fired power plants. New research explores the health and environmental costs of coal storage and transportation, finding that increases in the level of coal stockpiles held by US power plants increase local air pollution levels, which in turn increases the average infant and adult mortality rates in the communities near these plants. […]

  • Increased air pollution cuts victims' lifespan by a decade, costing billions
    on July 3, 2017 at 12:32 pm

    One of the benefits to cutting fossil fuel consumption is lowering air pollution. A new study shows that, on average, an increase in pollution particles in the air of 10 micrograms per cubic meter cuts victims' life expectancy by 9-11 years -- more than previously thought. But the estimated economic cost of this differs wildly between the US and the EU because of the calculations used. […]

  • Power to the people
    on June 30, 2017 at 4:44 pm

    The first rule of advocating for climate change-related legislation is: You do not talk about 'climate change.' The term has become so polarizing that its mere mention can cause reasonable people to draw seemingly immutable lines in the political sand. […]

  • Air pollution a concern at levels currently accepted as 'safe'
    on June 30, 2017 at 4:43 pm

    Government agencies must not become complacent in the effort to provide clean air to all citizens, warn authors of a new report. […]
