2011 Aug. 23: U.K. England, London: (Particulates) Dust Supressant & Vegetated Barriers among ideas to control particulates London Gets ‘Particulate’ About Air Quality TMC Net … binding European targets for Particulate Matter (PM) 10 and nitrous oxides. … She has worked extensively for MasterCard (News – Alert) Worldwide, … Excerpts: 1. The expansion of the application of dust suppressant — biodegradable saline solution (Calcium Magnesium Acetate) — which makes PM10 adhere to the roads and prevents it from recirculating in the air. The dust suppressant pilot study — a U.K.. first — ran from November 2010 to April 2011 at two locations, Victoria Embankment and Marylebone Road. Dust suppressant tests also have been conducted in Sweden, Norway, Austria, Italy and Germany At Victoria Embankment, alone, tests showed that small, repeated applications can effectively reduce PM10 at curbside locations by as much as 14 percent on a daily basis. The scheme will continue to run on Victoria Embankment and Marylebone Road and also will be introduced at Park Lane and corridors such as the A2. In addition, trials at industrial and construction sites will be launched, to help tackle the source of pollutants where there are high levels of PM10. Two additional vehicles are set to be converted to apply the dust suppressant, enabling the two trial sites to be expanded into more areas, including the construction sites. 3. A greening program throughout London will “trap” pollution and beautify the city. Studies across Europe and the U.S. have shown the potential of vegetation, including trees and plants, to trap PM10. A row of 50 six-foot-tall planters has been installed along Lower Thames Street, one of central London’s most polluted roads. The planters will contain summer bedding plants, to help trap particulate matter, and will be replaced with ivy in the winter. These stand-alone planted towers are being used to test the benefits of green screens (vegetated barriers), which are considered a feasible option for the roadside, where footways are wider, as they will not provide barriers to pedestrian movement or impede visibility. Other green infrastructure, including green walls and trees, will be placed at potential PM10 pollution hot spots across London. The Air Pollution Research in London Group (APRIL) is helping to evaluate the air quality, and wider environmental and climatic benefits of the green infrastructure measures
