  • Objectives: Pine needles are used as passive air samplers (PAS) of atmospheric persistent organic pollutants (POPs). This study was carried out in order to investigate whether pine needles can also be used as a PAS of polybrominated diphenyl ethers (PBDEs). Methods: PBDEs in one to three year-old pine needles were analyzed with HRGC/HRMS. Results: PBDEs in the atmosphere were accumulated in the pine needles. The rate of increase in concentration of lower substituted PBDEs (tri- through hepta-) in pine needles was linear. The rate of increase of the higher substituted PBDEs (octa- through deca-) was also liner, but only up to two year-old pine needles. The concentration did not increase further in older pine needles. Conclusion: Therefore, it can be concluded that young pine needles, those that are two years old or less, are recommended for use as PAS of atmospheric PBDEs.

  • The purpose of this study was to investigate usefulness of the pine needles extract on Atopic Dermatitis(AD)-like skin lesions. To investigate the effect of pine needles extract in vivo, atopic dermatitis (NC/Nga) mice using DNCB (2.4-Dinitrochlorbenzene) was used. NC/Nga mice were challenged with DNCB during 2 weeks to develope AD-like skin lesion. After that, pine needles extract was applied to AD-like skin lesion on the backs of the NC/Nga mice during 3 weeks. The efficacy of pine needles extract in the NC/Nga mice was evaluated by measurement of the skin lesion severity(NC mouse score), the serum IgE level, epidermal thickness changes, and mast cell number. Blood was collected from the retro-orbital area and the level of IgE in the blood was measured. The epidermal thickness and mast cell number were observed by microscopic method after H&E stain. The serum IgE levels were decreased after treatment with pine needles extract. The epidermal thickness and mast cell number were decreased after treatment with pine needles extract. To conclude, the topical application of pine needles extract suppressed the progression of AD-like skin lesion.

  • Results for the concentrations of total polychlorinated biphenyls (total PCBs) and the PCB profile with different types of leaves from four coniferous trees (pine needles) at the same sampling site are presented. Concentrations of total PCBs detected in pine needles were very similar among them regardless of their different types of leaves, which means a possibility for bio-monitoring regional contamination of PCBs. Correlation coefficients(r) of PCB congeners between pine needles were very significant (r>0.97, p<0.001), which showed that PCB congener's patterns of each pine needle were similar. Profiles of PCBs detected in pine needles showed correlation with gaseous phase PCBs in air, otherwise not with particle phase PCBs in air. Therefore, it was estimated that dry gaseous deposition was a principal pathway of PCBs accumulation in pine needles. In addition, although we analyse a different types of leaves in pine needles at the same region, they can be used to identify regional contamination patterns of PCBs for larger regions.

  • As a basic study for preparing pine sprout tea, chemical components in pine sprouts and pine needles were analyzed as follows: In proximate composition the contents of most components except for crude fat were different between in pine sprouts and pine needles. Moisture content in pine sprouts was higher than that in pine needles. Calcium and potassium were major minerals contained in pine sprouts and needles, and their contents in pine needles picked in December were higher than those picked in June. Soluble tannin and vitamin C contents in leaf part of pine sprouts were much higher than those in stem part and their contents in pine needles were increased according to their growth. Free sugars like fructose, glucose and sucrose were contained in both pine sprouts and needles, and their contents in pine sprouts were higher in stem part as compared that in leaf part. Although fourteen kinds of amino acids were detected in pine sprouts and pine needles, their contents were extremely low. Amino acid composition between pine sprouts and pine needles was different each other, but major amino acids contained in them were same, those are acidic amino acids such as aspartic acid and glutamic acid. Amino acid contents in pine needles were increased according to the growth. In fatty acid composition in leaf part of pine sprouts, saturated fatty acid contents were higher than unsaturated fatty acid contents, but in stem part unsaturated fatty acid contents were higher. In pine needles the amount of saturated fatty acid was increased with the growth, but the amount of unsaturated fatty acid was rather decreased.

  • Dyeing properties of cotton and ramie fabrics with pine needles colorants were studied by investigating the analysis of pine needles colorants, the effect of dyeing conditions (such as dye concentration, dyeing temperatures and times on dye uptakes), effect of mordants, and color change. The various colorfastness of dyed fabrics were evaluated for practical use; in addition, the antimicrobial ability, ultraviolet-cut ability, and deodorant ability were estimated. In the UV-Visible spectrum, the wavelength of the maximum absorption for pine needles extract was 285nm, and pine needles colorants produced a yellow color. From FT-IR and GC-MS results, it was assumed that chromophoric substance from pine needles extracts were mixed with flavonol tannin and flavanol tannin. An increased dyeing concentration resulted in a larger dye uptake and a Freundlich absorption isotherm was obtained. A larger dye uptake occurred as the dyeing time and temperature increased. Post-mordanting was more effective than pre-mordanting and the dye uptake of fabrics improved by mordanting. The colorfastness of dyed fabrics showed a low rating; however, colorfastness to washing and dry cleaning of cotton fabrics mordanted with N.Cu, and friction fastness of ramie fabric mordanted with Cu improved. The dyed fabrics showed very good antimicrobial abilities of 99.9%. In addition, the ultraviolet-cut ability and deodorant ability improved in fabrics dyed with pine needles extracts.

  • The pine needles can be used for four seasons in normal living and it can be taken friendly everywhere as it is distributed over 50% in Korea. The pine needles consist of vitamins, protein, minerals, essential oil and enzyme related to antimicrobial activity. It has effect like high blood pressure, neuralgia and hanged over by terpene, glucokinin, rutin, apigenic acid and tannin. Also the extract of them can be used for dyeing of fabrics. However, the extract components and effects of them are not well known yet. Therefore, the purpose of this study was to investigate the volatile components of the pine needles extract and functionality. The pine needles extract was dyed into various fabrics(nylon, silk, wool and soybean) and mordanted with Al, Cu, Cr, Fe and Sn. The extracted aroma compounds were compared by gas chromatography-mass spectrometry. The major volatile compounds of pine needles verified by using SPME were alpha-pinene, beta-pinene, beta-phellandrene, caryophyllene, ethanon, benzen. A total of 15 compounds were identified by using the SPME fibers. In the UV-visible spectra, the maximum absorption of wavelength of the pine needles ethanol extract appeared at 460, 630nm for chlorophyll component and at 237, 281nm for tannin component with the pine needles distilled water extract. Most of sample showed high antibacterial effect in none mordant but wool fabric showed high antibacterial effect in mordants. The result of UV block test showed a superior ability of blocking ultraviolet ray infiltration in all sample.

  • Objective: This study was carried out to use pine needles as a passive air sampler (PAS) for atmospheric polychlorinared dibenzo-p-dioxins/furans (PCDD/Fs). Methods: PCDD/Fs concentrations in ambient air ($C_a$, $pg/m^3$) and deposited pine needles ($C_p$, pg/g dry) were analyzed simultaneously from June 1 to December 31. Air samples were taken using two low volume PUF active air samplers with an overall average air volume of approximately $1,200Sm^3$. Pine needles were collected the end of December near the air sampler. PCDD/Fs was analyzed by HRGC/HRMs. Results: A good correlation was shown ($R^2=0.6357$, p=0.0001) between $C_a$ and $C_p$, but a better correlation ($R^2=0.7372$, p<0.0001) existed between the logarithm of octanol-air partitioning coefficient ($LogK_{oa}$) and Log($C_p/C_a$). The average PCDD/Fs sampling rates from air to pine needles were 0.045($0.018-0.185m^3/day-g\;dry$). Conclusion: It was found that pine needles can be used as PAS for atmospheric PCDD/Fs, and they are especially suitable for long time PAS compared to PUF disk PAS.
