New paper entitled “Variability of carbonaceous aerosols in remote, rural, urban and industrial environments in Spain: implications for air quality policy” has been published in Atmospheric Chemistry and Physics.

New publication in the journal Atmospheric Chemistry and Physics about variability of carbonaceous aerosols in Spain.

Seven research centre and universities have provided data of organic carbon, elemental carbon and back carbon measured in the PM10 and PM2.5 fractions of 78 sites of Spain. Measurements were performed in different environments, including remote and ultrafine sites such as the Izaña observatory in Tenerife (Canary Islands) to cities and industrial areas with a high degree of pollution. Results show that vehicle exhaust is a major source of carbonaceous aerosols in cities. These particles are residues of fuel that didn’t have a complete combustion in the engine. The study shows how in many Spanish cities concentrations of organic carbon and elemental carbon decreased significantly since 1999 to 2011 due to the reduction in the vehicle exhaust emissions prompted by the EURO 4 and EURO 5 standards.

The study was performed by the Research Council of Spain (CSIC), the Izaña Atmospheric Research Centre, the University of Huelva, University of Aveiro, University of Granada, CIEMAT and the Health Institute Carlos III.
