  • House sparrow decline linked to air pollution and poor diet
    on October 3, 2017 at 3:10 pm

    House sparrows are well-adapted to living in urban areas, so it is surprising their numbers have fallen significantly over the past decades. An investigation into this worrying trend finds that sparrows living in urban areas are adversely affected by pollution and poor nutrition. The study also finds the birds suffer more during the breeding season, when resources are needed to produce healthy eggs. […]

  • New study changes our view on flying insects
    on September 29, 2017 at 3:49 pm

  • Breathing dirty air may harm kidneys
    on September 22, 2017 at 1:16 pm

    Outdoor air pollution may increase the risk of chronic kidney disease and contribute to kidney failure, say researchers. Scientists culled national VA databases to evaluate the effects of air pollution and kidney disease on nearly 2.5 million people over a period of 8.5 years, beginning in 2004. The scientists compared VA data on kidney function to air-quality levels collected by the Environmental Protection Agency (EPA) as well as the National Aeronautics and Space Administration (NASA).

  • 5,000 deaths annually from Diesel-gate in Europe
    on September 18, 2017 at 1:33 pm

    Excess emissions from diesel cars cause about 5,000 premature deaths annually across Europe, a new study shows. Higher exposure to secondary particles and ozone can be traced back to excess NOx emissions from diesel cars, vans and light commercial vehicles. With the EU's vehicle emission limits achieved on the road about 5,000 premature deaths could be avoided annually. If diesel cars emitted as little NOx as petrol cars, about 7,500 premature deaths could be avoided annually. […]
