Objectives: Pine needles were used as a passive air sampler (PAS) of atmospheric persistent organic pollutants(POPs). This study was performed to investigate concentrations of polychlorinated dibenzo-p-dioxins anddibenzofurans (PCDD/Fs) deposited on pine needles near a waste incinerator and PCDD/Fs source contributionsusing principal component analysis (PCA).
Methods: Two-year-old pine needles were sampled at 11 points with respect to distance and wind direction fromthe incinerator. PCDD/Fs deposited on pine needles were analyzed with HRGC/HRMS. The source contributionof PCA was calculated with SPSS.
Results: The average concentration of PCDD/Fs deposited on pine needle was 0.79 (0.27-1.76) pg TEQ/g dry,PCDDs with 0.24 (0.01-0.95) pg TEQ/g dry and PCDFs with 0.56 (0.27-0.82) pg TEQ/g dry, respectively. Theaverage concentration fraction of PCDDs was 29.7%, that of PCDFs was 70.3%, and PCDFs were moreprevalent than PCDDs. The contributions of PCDD/Fs sources were estimated as incineration at 58.3% andautomobiles at 28.4%. However, a relation and regulation between PCDD/Fs concentrations deposited on pineneedles and distance from incinerator or wind direction was not shown.
Conclusion: It was concluded that atmospheric PCDD/Fs concentrations near an industrial complex with awaste incinerator were affected by multiple sources. However, PCDD/Fs concentrations were lower than in otherinland cities with the exception of background area.
