  • Genes, ozone, and autism
    on June 23, 2017 at 7:55 pm

    Exposure to ozone in the environment puts individuals with high levels of genetic variation at an even higher risk for developing autism than would be expected just by adding the two risk factors together, a new analysis shows. The study is the first to look at the combined effects of genome-wide genetic change and environmental risk factors for autism. […]

  • Wildfires pollute much more than previously thought
    on June 14, 2017 at 3:28 pm

    Wildfires are major polluters. Their plumes are three times as dense with aerosol-forming fine particles as previously believed. For the first time, researchers have flown an orchestra of modern instruments through brutishly turbulent wildfire plumes to measure their emissions in real time. They have also exposed other never before measured toxins. […]

    on May 31, 2017 at 2:33 pm

    A new study combining European ice core data and historical records of the infamous Black Death pandemic of 1349-1353 shows metal mining and smelting have polluted the environment for thousands of years, challenging the widespread belief that environmental pollution began with the Industrial Revolution in the 1700s and 1800s. […]

  • Natural gas facilities with no carbon dioxide emissions
    on May 24, 2017 at 12:46 pm

    How can we burn natural gas without releasing carbon dioxide (CO2) into the air? This feat is achieved using a special combustion method: chemical looping combustion (CLC). In this process, CO2 can be isolated during combustion without having to use any additional energy, which means it can then go on to be stored. This prevents it from being released into the atmosphere. […]

  • Fuel from the air technology provides a path to new business for OPEC countries
    on May 24, 2017 at 12:46 pm

    Pioneering technology makes OPEC countries prime regions to produce synthetic fuels. This could be a key asset in phasing out fossil fuels after the Paris Agreement, while also keeping some of the existing oil industry value chain intact. […]

  • Carcinogenic soot particles from petrol engines
    on May 23, 2017 at 6:43 pm

    First, diesel vehicles tainted their reputation with soot particles, then high nitric oxide emissions. So are owners of new gasoline cars environmentally friendly? Not always, says a new study scientists, some direct-injection gasoline engines emit just as many soot particles as unfiltered diesel cars did in the past. Particle filters can remedy this. […]

  • Smoke from wildfires can have lasting climate impact
    on May 23, 2017 at 12:33 pm

    Researchers have found that carbon particles released into the air from burning trees and other organic matter are much more likely than previously thought to travel to the upper levels of the atmosphere, where they can interfere with rays from the sun -- sometimes cooling the air and at other times warming it. […]

  • Computer code that Volkswagen used to cheat emissions tests uncovered
    on May 23, 2017 at 12:18 pm

    An international team of researchers has uncovered the mechanism that allowed Volkswagen to circumvent US and European emission tests over at least six years before the Environmental Protection Agency put the company on notice in 2015 for violating the Clean Air Act. During a year-long investigation, researchers found code that allowed a car's onboard computer to determine that the vehicle was undergoing an emissions test. […]

  • Environmental pollutants in large Norwegian lakes
    on May 19, 2017 at 5:16 pm

    Scientists have discovered the presence of contaminants in the pelagic food chains in the lakes Mjøsa, Randsfjorden and Femunden in Norway, and in supplementary material of fish from Tyrifjorden and Vansjø, sampled in 2015. Mercury and persistent organic pollutants (cVMS, PCBs, PBDEs, PFAS) were analyzed in samples of fish from all lakes, as well as pelagic crustaceans in Mjøsa. […]

  • Smoking out sources of in-home air pollution
    on May 18, 2017 at 6:38 pm

    An ambitious study has investigated various factors that contribute to air pollution inside the house. Not surprisingly, cigarette smoke emerged as a major source of airborne particles in homes with smokers, but cleaning products, candles, frying food and marijuana smoking also jumped out as in-home air polluters. It's the first study to identify marijuana as a significant source of in-home air pollution. […]

  • Earth's atmosphere more chemically reactive in cold climates
    on May 17, 2017 at 5:26 pm

    A Greenland ice core providing a first glimpse at the history of reactive oxidants shows that for big temperature swings in the past 100,000 years, reactive oxidants are actually higher in cold climates. This means that new mechanisms -- not just water vapor, plant and soil emissions -- must affect the concentration of ozone and other oxidants in the atmosphere. […]

  • During heat waves, urban trees can increase ground-level ozone
    on May 17, 2017 at 1:05 pm

    Planting trees is a popular strategy to help make cities 'greener,' both literally and figuratively. But scientists have found a counterintuitive effect of urban vegetation: during heat waves, it can increase air pollution levels and the formation of ozone. […]

  • Public divides over environmental regulation and energy policy
    on May 16, 2017 at 6:34 pm

    A 54 percent majority of US adults believe that 'government regulations are necessary to encourage businesses and consumers to rely more on renewable energy sources,' while 38 percent support the notion that 'the private marketplace will ensure that businesses and consumers rely more on renewable energy sources, even without government regulations,' according to a new survey. […]

  • Cities need to 'green up' to reduce impact of air pollution
    on May 16, 2017 at 2:47 pm

    The harmful impact of urban air pollution could be combated by strategically placing low hedges along roads in a built-up environment of cities instead of taller trees, a new study has found. […]
