Abstract

Dalian is a seaside city situated in the northeastern monsoon area of China. For the first time, levels of PCDD/F and PCB congeners in pine (Cedrus deodara) needles of Dalian urban areas were investigated. Two sampling campaigns with 17 sampling points were performed in 2002. The summation of tetra- to octachlorinated PCDD/Fs and summation of 209 PCB congeners in Dalian pine needles averaged 127 ± 40 ng/kg (dry) and 4389 ± 1575 ng/kg (dry), respectively. Average toxic equivalence (TEQ) for PCDD/Fs and PCBs are 2.1 and 0.4 ng/kg (dry), respectively. The pine needles can differentiate spatial variation of the pollutants. The PCDD/F and PCB levels in Dalian pine needles are low or comparable with other international regions that were not impacted by evident point sources. The data can serve as a base for long-term spatial and temporal studies of PCDD/Fs and PCBs in China.
