London may have the world’s most stringent rules against vehicle emissions by 2019, according to a proposal from Mayor Sadiq Khan.
Supplements of healthy fats could be an immediate way of cutting the harm caused to billions around the world by air pollution, according to emerging research.
However, the research also shows air pollution particles can penetrate through the lungs of lab animals into many major organs, including the brain and testicles. This raises the possibility that the health damage caused by toxic air is even greater than currently known.
Sadiq Khan issued the first “very high” air pollution alert of his eight-month tenure as London mayor, advising citizens to reduce physical exertion and avoid running outside.
Air pollution has been linked to heart disease for years, prompting concern as well as some skepticism, as the physiological steps showing a cause-and-effect have gone less understood. But now, a multi-year study has for the first time documented that air pollution thickens blood and hardens arteries, a condition that causes cardiovascular problems like heart attacks and strokes.
Outdoor air pollution contributed to 3.3 million deaths worldwide in 2010, with wood-burning stoves in China and India and ammonia-belching farms in the West among the biggest culprits, according to a new study.
And if nothing is done, the annual toll from dirty air may double to 6.6 million premature deaths by 2050, with the biggest rise coming in Asia, researchers said Wednesday in the journal Nature. The study used new atmospheric models and emissions data to offer a more comprehensive view of pollution sources and how the effects vary across the globe.
