Professor Alexander Baklanov of the World Meteorological Organization talks to Colin Sowman about the difficulties of reducing urban pollution. The inhabitants of Beijing have recently been suffering pollution levels 20 times the World Health Organisation’s recommended limit while the European Union is revitalising its efforts to implement and enforce air quality standards. Almost inevitably much of the clean-up efforts are likely to focus on traffic planners and engineers.
A new report, produced by experts at King's College London, for the first time quantifies the health and economic effects of the air pollutant nitrogen dioxide (NO2), where all previous studies have focused on particulate matter (PM2.5).
Combined together the effects of both pollutants reveal a higher health impact than previously estimated after taking into account this further pollutant. The study also found that nearly half the health impacts are caused by air pollution outside London such as diesel
