  • Environmental exposures more determinant of respiratory health than inherited genetics
    on March 6, 2018 at 4:54 pm

    Researchers have found strong evidence that environmental exposures, including air pollution, affect gene expressions associated with respiratory diseases much more than genetic ancestry. The study analyzed more than 1.6 million data points from biological specimens, health questionnaires and environmental datasets, making this study one of the largest ever to examine the relationship between gene expression and environmental stimuli. […]

  • Global fossil fuel emissions of hydrocarbons are underestimated
    on February 26, 2018 at 6:14 pm

    Global levels of ethane and propane in the atmosphere have been underestimated by more than 50 percent, new research has revealed. These hydrocarbons are particularly harmful in large cities where, through chemical reactions with emissions from cars, they form ozone -- a greenhouse gas which is a key component of smog and directly linked to increases in mortality. […]

  • Nitrate flux in the Arctic not following the decreasing NOx emissions in neighboring countries
    on February 20, 2018 at 2:49 pm

  • High levels of microplastics found in Northwest Atlantic fish
    on February 16, 2018 at 4:05 pm

    A new study finds 73 percent of mesopelagic fish caught in the Northwest Atlantic had microplastics in their stomachs -- one of the highest levels globally. Typically living at depths of 200-1,000 meters, these fish could spread microplastic pollution throughout the marine ecosystem, by carrying microplastics from the surface down to deeper waters. They are also prey for fish eaten by humans, meaning that microplastics could indirectly contaminate our food supply. […]

  • Rapid pollution increases may be as harmful to the heart as absolute levels
    on February 15, 2018 at 11:03 pm

    Rapid increases in pollution may be as harmful to the heart as sustained high levels, according to new research. The authors urgently call for confirmatory studies as even residents of clean air cities could be at risk. […]

    on February 15, 2018 at 7:18 pm

    Chemical products that contain compounds refined from petroleum, like household cleaners, pesticides, paints and perfumes, now rival motor vehicle emissions as the top source of urban air pollution, according to a surprising new study. […]

  • 'Excess emissions' make significant contribution to air pollution
    on February 14, 2018 at 2:38 pm

    A study shows that excess emissions -- which occur with plant shut-downs, start-ups and malfunctions, and not just in connection with natural disasters -- can make serious contributions to overall air pollution. […]

  • Polluted air may pollute our morality
    on February 7, 2018 at 8:18 pm

    Exposure to air pollution, even imagining exposure to air pollution, may lead to unethical behavior, according to new findings. A combination of archival and experimental studies indicates that exposure to air pollution, either physically or mentally, is linked with unethical behavior such as crime and cheating. The experimental findings suggest that this association may be due, at least in part, to increased anxiety. […]

  • Powerful new dataset reveals patterns of global ozone pollution
    on February 5, 2018 at 7:11 pm

  • Central Valley soil emissions a large source of California's nitrogen oxide pollution
    on January 31, 2018 at 9:03 pm

    A previously unrecognized source of nitrogen oxide is contributing up to about 40 percent of the NOx emissions in California, according to a new study. The study traces the emissions to fertilized soils in the Central Valley region. […]

  • Tiny particles have outsize impact on storm clouds, precipitation
    on January 25, 2018 at 7:09 pm

    Tiny particles fuel powerful storms and influence weather much more than has been appreciated, according to a new study. While scientists have known that aerosols may play an important role in shaping weather and climate, the new study shows that the smallest of particles have an outsize effect. The tiny pollutants -- long considered too small to have much impact on droplet formation -- are, in effect, diminutive downpour-makers. […]

  • Air pollution linked to irregular menstrual cycles
    on January 25, 2018 at 5:04 pm

    The air your teenage daughter breathes may be causing irregular menstrual cycles. Well documented negative health effects from air pollution exposure include infertility, metabolic syndrome and polycystic ovary syndrome. This study is the first to show that exposure to air pollution among teen girls (ages 14-18) is associated with slightly increased chances of menstrual irregularity and longer time to achieve such regularity in high school and early adulthood. […]

  • Air pollution may shorten telomeres in newborns -- a sign of increased health risks
    on January 24, 2018 at 1:55 pm

  • Use of dirty heating oil in New York City concentrated uptown
    on January 22, 2018 at 8:08 pm

    Residential buildings that continued to burn residual fuel oil were concentrated in Northern Manhattan and the Bronx, as of late 2015. Compared to cleaner heating sources such as natural gas, these dirty fuels produce high levels of particulate matter, exposure to which is linked to asthma, obesity, developmental delays, and other health problems. […]

  • The scent of the city
    on January 22, 2018 at 8:07 pm

    In a new study, researchers present the world's first chemical fingerprint of urban emission sources of volatile organic compounds (VOCs). Accordingly, the abatement strategy for organic solvents is having an effect in Europe. At the same time, the data suggest that the total amount of human-made VOCs globally is likely to be significantly higher than previously assumed. […]

  • Research helps break ground to clean up land
    on January 22, 2018 at 4:08 pm

    Researchers have been exploring the intricate shapes that emerge when air is injected into soil. These findings could one day be used to speed up the decontamination of industrial brownfield sites. […]

  • 20 percent more trees in megacities would mean cleaner air and water, lower carbon and energy use
    on January 18, 2018 at 9:24 pm

    Planting 20 percent more trees in our megacities would double the benefits of urban forests, like pollution reduction, carbon sequestration and energy reduction. The authors of the study say city planners, residents and other stakeholders should start looking within cities for natural resources and conserve the nature in our urban areas by planting more trees. […]

    on January 9, 2018 at 4:24 pm

    Smoke plumes emanating from wildfires are swept high up into the air and spread over thousands of kilometers even days after a fire has been put out. The fine particles and harmful ozone contained in these plumes often have devastating effects on the air quality of US cities and consequently the health of their inhabitants. […]
