Appalling Mongolian Air Pollution

March 10th, 2016

Episode 83 of 158 episodes

Fast growing cities like Beijing, New Delhi and Ulan Bator suffer from increasing air pollution – with ever larger numbers of motor vehicles and developing industries, the smog often clouds the air and causes health problems. Ulan Bator faces a special challenge because the winters are exceptionally cold. Many people in Mongolia’s capital city live in traditional yurts that are heated with coal fires. Temperatures down to -40 degrees Celsius keep the smoke from the fires from dispersing. Dr Purevdorj Olkhanud, from the Mongolian National University of Medical Sciences, travels back and forth between the US and Mongolia, where he gathers data on air quality in Ulan Bator to improve the public health situation. Senegal Science Meeting The Next Einstein Forum is underway in Senegal, aiming to encourage more women into science across Africa. Julian Siddle reports from Dakar.
