Polychlorinated biphenyls at the JRC Ispra site Air concentrations, congener patterns and seasonal variation: results from the 1st year of atmospheric monitoring of persistent organic pollutants at the Ispra EMEP station

Funded under: FP7-JRC

Abstract

With the aim of gather information on atmospheric POPs concentrations in one of the "monitoring holes" in Europe, a monitoring and research atmospheric site was set up at the JRC Ispra Site. Regular monitoring activities started on April 2005 and finished on March 2007 in this first stage. Air and precipitation samples were collected regularly throughout this period. First results obtained on PCBs ambient air concentrations (7 PCB indicators, 28, 52, 101, 118, 153, 138 and 180) from the first year of monitoring (April 2005-2006) are presented in this report. In addition, congener patterns, air gas/particulate phase partition and seasonal variation are discussed. The range of total (gas+particulate phases) monthly averaged concentration during the sampling period varied from 76 +/-17 to 31 +/- 5 pg m-3. Concentrations are within the range of those reported for rural, semi-rural or remote areas around the world. PCB-52 dominated the congener pattern of air gas phase and total concentrations whereas heavier congener dominated the air particulate phase pattern. A seasonal variation of air concentration was observed, with higher concentration in summer months (higher average temperatures) and lower concentration in winter (lower average temperatures). PCBs were in general predominant in the air gas phase (especially the lighter congeners) dominating therefore the contribution to the total airborne concentration.
