New campaign to evaluate Calcium Magnesium Acetate to reduce particle pollutants emissions

Previous studies in London, Austria and Sweden suggest that the application of the additive CMA (Calcium Magnesium Acetate), a totally safe product, to the water used to clean roads in urban areas can reduce air pollution caused by PM10 (particulate matter with diameter less atmospheric to 10 microns) generated by resuspension of particles deposited on the roadway. The reduction in emissions is due to the property of the CMA to link pollutant particles and keep them attached to the road surface.

On a trial basis, AIRUSE project evaluates the effectiveness of an aqueous solution of CMA (25% Calcium-Magnesium Acetate, 75% water) scattered in the driveway of Industria street (between Gaudi avenue and Biscaia street) in Barcelona. The additive will be spread up 10 times in the period April-May 2013. The study is conducted by the Institute of Environmental Assessment and Water Research (IDAEA) of the National Research Council (CSIC) and the Barcelona City Council (Serveis d’Intervenció i Innovació Mediambiental) with the close collaboration of the Generalitat de Catalunya (Department de Territori i Sostenibilitat) and the Diputació de Barcelona (Oficina Tècnica d’Avaluació i Gestió Ambiental).

The scientific and technical activities are carried out by means of:

  • Four Air Pollution Mobile Units equipped with numerous air pollutants samplers and measurement instruments
  • Spreader Vehicle aqueous solution
  • Cleaning Vehicles BCNeta with pressurized water
