        일반 인구집단에 대한 대기중 총먼지의 생물학적 노출지표로서 요중 1-hydroxypyrene 및 2-naphthol의 유용성

        강종원,김헌,강대희,이철호,조수헌,Kang, Jong-Won,Kim, Heon,Kang, Dae-Hee,Lee, Chul-Ho,Cho, Soo-Hun 대한예방의학회 2000 Journal of Preventive Medicine and Public Health Vol.33 No.3

        Background : Polycyclic aromatic hydrocarbons (PAH) are well known environmental pollutants. The measurement of PAH in ambient air is not commonly used, because it is quite difficult to perform and is unreliable. Using biomarkers of PAH can be an alternative approach to this problem. The PAH in ambient air is absorbed in particulate matter. Total suspended particulate(TSP) or particulate matter of less than $10{\mu}m$ in diameter (PM10) can be easily measured. Therefore, TSP or PM10 can be used as a surrogate measurements of ambient air PAH. Objectives : We investigated whether the urinary concentration of two biomarkers of PAH, 1-hydroxypyrene (1-OHP) and 2-naphthol, could reflect the total suspended particulate in the general population. Methods : In order to exclude the effects of occupational exposure and smoking, first grade middle school students were included in this study. Four middle schools within a one kilometer boundary of ambient air monitoring stations were selected. Total suspended particulate was regarded as the marker of airborne PAH. Diet and smoking data were collected by self administered questionnaires, and spot urine samples were collected. Urinary 1-OHP and 2-naphthol were analyzed by high performance liquid chromatography. Results : The correlation between urinary 1-OHP, 2-naphthol and passive smoking was not statistically significant. The correlation between urinary 1-OHP and TSP indices was not statistically significant. The correlations between urinary 2-naphthol and TSP of two lag days, one lag day, and zero lag days were statistically significant. The statistical significance of two lag days was the strongest (p=0.001), one lag day was the next (p=0.0275), and zero lag days was the weakest (p=0.0349). Conclusion : Our results imply that the urinary concentration of 2-naphthol can be applied as a PAH exposure marker for the general population with low PAH exposure.

        허문영(Moon Young Heo),권창호(Chang Ho Kweon),유기선(Ki Seon Yu),최성규(Seong Kyu Choe),김경호(Kyeong Ho Kim),손동헌(Dong Hun Sohn) 대한약학회 1990 약학회지 Vol.34 No.1

        Total suspended particulate (TSP) in the atmosphere was collected and size-fractionated by Andersen high volume air sampler for the past two years (Mar. 1987-Feb. 1989) in Seoul. The concentrations of several Polycyclic aromatic hydrocarbons and heavy metals were determined to investigate the atmospheric concentrations, seasonal variations and its relationship with the size distribution of suspended particulate matter. The arithmetic mean concentration of total suspended particulate was 229.48mcg/m3. The concentrations of heavy metals were 2971.94ng/m3 for Fe, 767.75ng/m3 for Zn, 765.80ng/m3 for Pb, 218.40ng/m3 for Cu, 129.91ng/m3 for Mn, respectively. And the concentration of PAHs were 3.23ng/m3 for benzo(a)pyrene, 2.71ng/m3 for benzo(k)fluoranthene, 4.53ng/m3 for benzo(ghi)perylene, respectively. The mass-size distribution of TSP was lowest in the particle size range 1.1-3.3mcm increased as the particle size increased or decreased. But PAHs, Pb and Zn abounded in particles below 2.0mcm, while Fe and Mn abouned in particles above 2.0mcm. TSP and its chemical compositions showed the seasonal variations. The concentrations of anthrophogenic origin like TSP, PAH and heavy metals in the fine particles were highest in winter and lowest in summer. PAH and Ph analyzed showed significant correlations with each other and with TSP concentration in fine particles, indicating that the particles in which they are contained have a similar behavior in the atmosphere.

      • Soil Ecological Effects of Chainsaw Lubricant Contamination by Oil Type in a Forest Nursery Field

        Ikhyun Kim,Jeongjae Kim,Eugene Ha,Byoungkoo Choi 강원대학교 산림과학연구소 2022 강원대학교 산림과학연구소 학술대회 Vol.2022 No.10

        Tree cutting is commonly performed using chainsaws in South Korea. While the chain is rotating, the oil pump releases lubricant from the reservoir on the guide bar as the throttle is pressed. Sawdust, stained with released lubricant, is sprayed on the surface soil during tree cutting. And some released lubricant droplets are scattered on the ground directly. This study was conducted to assess the effect of lubricant on forest soil properties in a nursery field. We examined the persistence of 16PAHs and TPH in lubricant scattered soil and monitored the changes in soil biological properties (soil respiration, soil bacterial community richness and diversity) from November 15th, 2021 to September 19th, 2022. The research site included a total of 4 plots consisting of one control plot (CP) and three treatment plots (T-plot), and each plot consists of three subplots (3✕3 m; a total of 12 subplots). Three different types of lubricants of 100 ml/m2 were scattered on the soil surface of each T-plot (Bio-oil scattered plot, BP; Premium mineral oil scattered plot, PMP; Mineral oil scattered plot, MP) on November 16th, 2021. After approximately six months of lubricant scattering treatment, the concentration of soil increased in BP by 346.9%, PMP by 138.1%, MP by 691.9%, and soil TPH concentration decreased in BP by 48.2%, PMP by 24.0%, and increased in MP by 124.5%. The average soil respiration within the study period was lower at PMP (0.46 g CO2/m2/hr) than at CP (0.54 g CO2/m2/hr), BP (0.57 g CO2/m2/hr), and MP (0.59 g CO2/m2/hr), but there was no significant difference (p<0.05). In addition, lubricant type had no significant effect on soil bacterial community richness and diversity during the study period (p<0.05).

        Assessment of the geo-environmental effects of activities of auto-mechanic workships at Alaoji Aba and Elekahia Port Harcourt, Niger Delta, Nigeria

        Nkanu Ernest Muze,Alexander Iheanyichukwu Opara,Francis Chizoruo Ibe,Okereke Chinwendu Njoku 환경독성보건학회 2020 환경독성보건학회지 Vol.35 No.2

        Geo-environmental assessment of activities of auto–mechanics at Alaoji Aba and Elekahia Port Harcourt, both in the Niger Delta region, Southern Nigeria were carried out with the main objective of determining the extent of soil contamination arising from anthropogenic activities within mechanic villages (MVs). Geochemical analysis of soil samples from the study area revealed that the concentrations of the trace metals ranged from <1 mg/kg for chromium (Cr) to 1,925 mg/kg for the lead (Pb). Soil analysis for polycyclic aromatic hydrocarbon (PAH) and total petroleum hydrocarbon (TPH) across the area revealed concentrations ranging from <0.02 to 1.80 mg/Kg and from <1.00 to 38,327 mg/kg respectively. Elevated levels of the heavy metals and TPH were observed at MV in Alaoji Aba when compared to MV in Elekahia Port Harcourt, and the control sites. These could be attributed to contamination due to the presence of these auto-mechanics in the area for over thirty years. The concentration of Pb and Cd recorded in some sample points were above USEPA (United State Environmental Protection Agency) and the National Environmental Standards and Regulations Enforcement Agency (NESREA) permissible limits. Results of PAH analysis showed the presence of naphthalene, phenanthrene, pyrene, fluorene, benzo(a)anthracene, acenaphthene, methylnaphthalene. Risk assessment analysis showed significant geo-accumulation values for Cd and Pb indicating heavy contamination. The monomial risk factor of the heavy metals in the MVs are in the order Cd >Pb>Cr, while potential ecological risk index analysis showed values indicating very high risk, considerable risk and a moderate risk to the area under study as well as the surrounding environment. These results suggest that the soils from the MVs which represent the mechanic workshops at Alaoji Aba and Elekahia Port Harcourt are considered to be of pollution concern due to elevated Pb and Cd levels. Hence, there is a serious need to regularly monitor the activities of auto-mechanics in the study area.
