Niveles y fuentes de elementos traza e hidrocarburos aromáticos policíclicos en depósitos atmosféricos en Cantabria

Abstract

Atmospheric deposition is the transfer of substances from the atmosphere to the surface. These substances include trace elements or polycyclic aromatic hydrocarbons (PAHs). Sampling, Characterization and evaluation has been carried out in four different sites of Cantabria region representing industrial, urban, rural and traffic environments. Trace elements levels varied depending on the studied area. Furthermore, common and local sources were identified in the different sites. In addition, Zn and Mn were identified as the main tracers in the urban site according to PMF model. Otherwise, PAHs levels depended on the area studied, showing the industrial site the highest levels. Finally, with the aim of studying emission sources diagnostic ratios were used.
