Professor David Newby, Director of the Edinburgh Clinical Research Facility, presents the second lecture in the 2014 Our Changing World series, entitled "Air Pollution and Heart Attacks". Air pollution is one of the leading causes of heart attacks and death world-wide. This is principally caused by nano-particles generated by the combustion of fossil fuels and vehicle engine emissions. Although the highest levels of air pollution are seen in developing countries, even modest levels of air pollution in Europe and North America can cause substantial adverse health effects. The lecture will cover the size of the problem, explore the scientific evidence and highlight ways to reduce the risk. http://www.ed.ac.uk/about/edinburgh-global/academies/changing-world/2014-lectures/air-pollution-heart-attacks Recorded on Tuesday 30 September 2014 at the University of Edinburgh's Appleton Tower.
