Prof. Duncan Laxen, Managing Director of Air Quality Consultants Ltd, was invited by the UK Royal Academy of Engineering to give a presentation to a delegation from the Environmental Protection Department of Hunan Province in central China.
He outlined the UK approach to the control of air pollution, showing the tiers of influence, from the European Union down to Local Authorities, that all have a part to play. He then described the current understanding of PM2.5 sources in the UK, emphasising the complexity of the challenge to control exposure to PM2.5, given the many different primary and secondary sources.
The Chinese delegation was keen to learn from UK experience given the extreme pollution levels that occur in Hunan. They noted that the Hunan Province has a population similar to that of the UK.
