Short summary

The ambient concentration of many air pollutants in Europe has decreased in these last decades thanks to the effectiveness of the pollution control measures implemented at European or regional/local levels. In this work we studied the trends of the concentrations of many different pollutants during the period 2004–2014, reporting on the type of trend, magnitude of the trend, and its statistical significance. Data from two twin sites in NE Spain (regional and urban background) were used.
