N2 - Pine needles were sampled to determine levels of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and metals in Scots pine (Pinus sylvestris) needles at industrial, urban and background sites in Sweden (SW), Czech Republic (CZ) and Slovakia (SK). Spatial and temporal patterns of PCDD/Fs in pine needles were investigated and principal component analysis (PCA) used to determine spatial patterns, potential sources and transport of PCDD/Fs. Levels of PCDD/Fs in pine needles were generally greatest near to industrial sites (Sigma 2,3,7,8-PCDD/Fs (lower bound (LB)): 6 ng kg(-1) 190 ng kg(-1)) compared to urban and background sites (Sigma 2,3,7,8-PCDD/Fs (LB): 0.90 ng kg(-1) - 20 ng kg(-1)). Using metal contamination in pine needles helped to detect spatial patterns and separate local thermal sources of PCDD/Fs. (C) 2016 Elsevier Ltd. All rights reserved.
