The weakest association was found for ozone. In addition, particulate matter made up of particles in the air such as dust, pollen, soot and smoke was included. PM 2. 5 (fine particles less than 2. 5 micrometres in size) and PM 10 (coarse p.
ydrology and Meteorology, said. When such blankets of smog block sunlight, sending temperatures down, people make fire from wood, cow dung cake and hay to warm themselves and that creates more air pollution that leads to denser smog. Scientists say the real trouble is that smog during winter cannot escape to the upper atmosphere as it can during other seasons, because of meteorological conditions. "During winter, the cold air that blows towards the southwest from the northeast tends to push the boundary layer the layer of atmosphere closest to the Earth Nike Air Max 90 2017 surface low," William Lau, deputy director for atmospheres at NASA's Goddard Space Flight Center, said. "As a result, all the pollutants get trapped in the boundary layer that is pushed down to as low as one kilometre from the Earth's surface while it Nike Air Max 2017 Black And Gold

Scientists at Edinburgh University said common risk factors for stroke include obesity, smoking and high blood pressure, but evidence of environmental factors such as air pollution is lacking. They analysed 103 observational studies covering 28 countries and looking at gaseous pollutants including carbon monoxide, sulphur dioxide, nitrogen dioxide Nike Air Max 2017 Mens Grey

"The cold wave becomes severe because of this local trapping of the aerosols and other pollution that block off the solar radiation and create very unhealthy air in this part of the world," he added. Air pollution is linked to a higher risk of stroke and is also associated with anxiety, according to research.
