AB  - In this study, organochlorine pesticides (OCPs) and polycyclic aromatic 
      hydrocarbons (PAHs) in needle leaves with different ages were measured in three 
      prevalent coniferous forests including spruce, fir and pinus in southeast Tibetan 
      Plateau (TP) to investigate accumulation behavior of persistent organic 
      pollutants (POPs) during entire growth cycle of needles. The accumulation 
      concentration of POPs was higher in pinus and fir needles than in spruce needles. 
      Concentrations for most of OCPs significantly increased with needle ages, 
      especially dichlorodiphenyltrichloroethane (DDT) and its metabolites showed more 
      remarkable increasing trend than hexachlorocyclohexane isomers (HCHs) and 
      hexachlorobenzene (HCB) in the three tree species. However, age dependence 
      accumulation of PAHs was not observed in most cases, possibly due to its easier 
      degradation property and the influence by dramatic change of ambient atmospheric 
      concentration of PAHs. The lipid normalized concentrations in needles exhibited 
      similar accumulation pattern with that of dry weight basis. The controlling 
      factors for concentration variation in needles were identified using multiple 
      linear regression. The suitability of these needle species acting as potential 
      passive sampler for atmospheric POPs was evaluated. The different-age needles 
      could reflect atmospheric OCP concentrations in the past long-term trend. 
      Findings of this study provide guidance in use of needle as passive samples for 
      the background monitoring of the atmospheric contamination at remote and poorly 
      accessible locations such as the TP.
