AB  - The estimation of benzo(a)pyrene (BaP) concentrations in ambient air is very 
      important from an environmental point of view especially with the introduction of 
      the Directive 2004/107/EC and due to the carcinogenic character of this 
      pollutant. A sampling campaign of particulate matter less or equal than 10 
      microns (PM10) carried out during 2008-2009 in four locations of Spain was 
      collected to determine experimentally BaP concentrations by gas chromatography 
      mass-spectrometry mass-spectrometry (GC-MS-MS). Multivariate linear regression 
      models (MLRM) were used to predict BaP air concentrations in two sampling places, 
      taking PM10 and meteorological variables as possible predictors. The model 
      obtained with data from two sampling sites (all sites model) (R(2)=0.817, 
      PRESS/SSY=0.183) included the significant variables like PM10, temperature, solar 
      radiation and wind speed and was internally and externally validated. The first 
      validation was performed by cross validation and the last one by BaP 
      concentrations from previous campaigns carried out in Zaragoza from 2001-2004. 
      The proposed model constitutes a first approximation to estimate BaP 
      concentrations in urban atmospheres with very good internal prediction 
      (Q(CV)(2)=0.813, PRESS/SSY=0.187) and with the maximal external prediction for 
      the 2001-2002 campaign (Q(ext)(2)=0.679 and PRESS/SSY=0.321) versus the 2001-2004 
      campaign (Q(ext)(2)=0.551, PRESS/SSY=0.449).
