► A method of collecting samples of exhaust gases to determine the concentration of PCDDs/Fs and HCB. ► A method od PCDDs/F and HCB determination in the same extract of analysed sample was elaborated. ► Concentration of PCDDs/Fs and HCB in exhaust gases from different sources of emission in Poland. The subject of this study was to develop a method of simultaneous determination of PCDDs/PCDFs and HCB in exhaust gases from industrial installations. Sampling to determine PCDDs/PCDFs was conducted using the method described in PN-EN 1948-1: 2006, where the sorption material is polyurethane foam (PUF). In order to simultaneously collect PCDDs/PCDFs and HCB and to avoid sorbent bed breakthrough, it was necessary to apply an additional polyurethane sorption layer. Twenty-seven samples of exhaust gases from various cement plants and 40 samples of exhaust gases from hospital and industrial waste incineration plants collected in 2009/2010 in the entire territory of Poland were examined. The average content of PCDDs/Fs in samples from cement plants amounted to 0.076ngI-TEQNm−3 (range of 0.002–0.62ngI-TEQNm−3), while the average content of HCB amounted to 10ngNm−3 (range of 0.98–60.5ngNm−3). In the case of samples collected from waste incineration plants, the average concentration of PCDDs/Fs was 0.39ngI-TEQNm−3 (range of 0.002–5.68ngI-TEQNm−3). In the case of HCB, the average concentration was 238ngNm−3 (range of 3.21–2500ngNm−3). Also, the interdependence of the concentration of PCDDs/PCDFs and HCB was determined in the analysed samples, with the ranges of low and high content of PCDDs/PCDFs being examined separately. In all cases, the determined values of the r correlation coefficient were within the range of 0.7–1.0, which indicates a good correlation between the concentrations of PCDDs/PCDFs and HCB.
