“…Table 2 lists data that have been published. Korean pine needles contain the highest PCDD/F concentrations, 26.2−2088 pg/g dw 18 and 10.1−155 pg/g wet weight. 28 Chinese pine needles were found to have high levels relative to other developed countries such as Japan, 17 Germany, 12 and Poland.…”

Many studies have shown that pine needles are a good biomonitor for atmospheric concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). However, this biomonitor has not been tested in large areas, and the quantitative relationship between concentrations in pine needles and air has not been established. In the present study, we collected pine needles from 38 cities in China. The concentrations of 2,3,7,8-PCDD/ Fs were measured by gas chromatography combined with high-resolution mass spectrometry. The total PCDD/F concentrations ranged from 5.4 to 330 pg/g dry weight of pine needles. The pine needles from cities located in central China and three major city agglomerations contained high concentrations of PCDD/Fs, while those from cities in the west and on the coast contained relatively low concentrations. Primary emission and diffusion processes were the main controls of the PCDD/F concentrations in pine needles. Homologue profiles of PCDD/Fs in pine needles were characterized by PCDFs/ PCDDs >1 in the industrialized cities and <1 in unindustrialized cities. The congener patterns were dominated by 1,2,3,4,6,7,8-HpCDF and OCDD, indicating that combustion was the major source of the PCDD/Fs. By comparing the PCDD/F concentrations in the pine needles and those in air, we established a preliminary linear relationship between them. Finally, the concentrations in air of PCDD/Fs in the 38 cities of China could be predicted from this relationship.

“…They had been used for monitoring PCDD/Fs, polychlorinated biphenyls, and other chlorinated organic compounds in the environment (Safe et al 1992;Kylin et al 1994;Strachan et al 1994;Ok et al 2002;Hanari et al 2004;Bochentin et al 2007;Wyrzykowska et al 2009;Falandysz et al 2012). To monitor PCDD/Fs in the atmosphere, Ok et al (2002) studied pine needle samples collected from 30 points in five cities in South Korea between 1998and 1999, and Bochentin et al (2007 studied 25 Scotch pine needle samples collected at various sites across Poland between October 21 and 27, 2002. Chen et al (2012) reported PCDD/Fs concentrations in pine needles in 38 cities in China.…”

PCDD/Fs accumulation in pine needles: variation with species and pine needle age

Pine needles have been used for many decades as a cheap and convenient biosampler to monitor atmospheric levels of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), collectively known as PCDD/Fs. However, it is unknown whether accumulation of PCDD/Fs varies according to pine tree species or pine needle age, which hampers the precise application of this biosampler. We collected 0.3-2.3-year-old pine needles from four different species of pine at three sites in Hangzhou City, Zhejiang Province, China. The PCDD/Fs were quantitatively analyzed by gas chromatography high-resolution mass spectrometry. The results show that Pinus massoniana and Cedrus deodara absorbed more PCDD/Fs than Pinus thunbergii and Pinus parviflora at the same site. More cuticular wax and cuticular cell secretions in the pine needles from P. massoniana and C. deodara, as observed by scanning electron microscopy (SEM), might explain this discrepancy. The PCDD/Fs concentrations in 0.3-, 1.3-, and 2.3-year-old pine needles, indicated that concentrations increase with ascending age. This may be ascribed to the enhancement of lipids and cuticular waxes with age in pine needles as indicated by the lipid contents and morphologies observed by SEM. Our results may be useful for selecting the species and age of pine needles used for biosampling, especially for monitoring PCDD/Fs in large areas where the pine species growing in one place may differ from those in another place.

“…2,3,7,3,7, is considered as the most toxic dioxin congener according to the World Health Organization toxic equivalent (WHO-TEQ) scheme (Hornung et al, 1996). As a consequence, numerous studies have been focused on the contamination of dioxin congener in various environmental compartments (Draper et al, 1988;Ok et al, 2002;Mai et al, 2007).…”
