Abstract [en]
Short chain chlorinated paraffins (SCCPs) have been of considerable concern in recent years due to their high production volumes, environmental persistency and potential for long range atmospheric transport. Vegetation can take up considerable amounts of semivolatile organic compounds from the atmosphere and can act as indicators of local contamination. Paired pine needles and bark were sampled around Beijing during winter and summertime to investigate the distribution of SCCPs in urban areas. Levels in bark samples ranged 5.79-37.5 mu g/g on a lipid normalized basis (lw) with a geometric mean (GM) of 16.9 mu g/g lw whereas levels were 3.03-40.8 (GM 11.8) mu g/g lw for needles. Average congener group abundance profiles showed equal contribution of all four carbon groups (C10-13) in wintertime whereas higher abundances of C-10 and C-11 groups were found during summer. Uptake of SCCPs occurred mainly via kinetically limited gaseous deposition and particle bound deposition in the investigated area.
