Not sure how applicable this phenomenon is to Edinburgh! It seems that trees and vegetation do act as barriers and filters for pollution - minimizing the spread! The buzzwords being deposition and dispersion! <a href="http://www.sciencedirect.com/science/article/pii/S1352231015000758">http://www.sciencedirect.com/science/article/pii/S1352231015000758</a> Agree that fundamentally we should deal with the sources of pollution rather than the symptoms!

This is a harmful pollutant at street level. It damages cells, injures lung function among vulnerable groups and has been linked to heart disease. Ozone is also toxic to plants. Wenger stresses that tree emissions are not in themselves pollutants but can mingle with pollutants to create air-quality problems. We should bear this in mind when choosing tree types. There's your problem. ivangrozni on ""The city trees that pose a threat to human health"" http://citycyclingedinburgh.info/bbpress/topic.php?id=16124#post-213441 Fri, 04 Mar 2016 12:46:28 +0000 ivangrozni 213441@http://citycyclingedinburgh.info/bbpress/ <a href="http://www.irishtimes.com/news/science/the-city-trees-that-pose-a-threat-to-human-health-1.2548050">http://www.irishtimes.com/news/science/the-city-trees-that-pose-a-threat-to-human-health-1.2548050</a> Interesting article! Maybe the tree felling by Roseburn park is a blessing in disguise!
