London, Oct 29 : The first ozone measurement taken on the summit of Mount Everest has revealed surprisingly high levels of ozone, which scientists involved in the expedition suggest might have originated from urban pollution.
According to a report in Nature News, the measurement was made by British climber Ian Wade, part of the Karrimor 2005 Everest Expedition, who carried an ozone meter the size of a pack of cards to the mountain’s peak, more than 8,800 meters above sea level.
John Semple from the University of Toronto, Canada, who was team doctor for the expedition, said that Wade had to memorize the measurement.
