Objectives: This study aimed to survey the characteristics of air quality and meteorological conditions in a greenway park. Methods: We measured meteorological and health related factors, including noise, particulate matter ($PM_{10}$) and selected gaseous air pollutants at three locations in a greenway park and on a general roadside as comparison. The measurements were repeated four times from April to October 2014. Results: The average air temperature in the greenway park was $20.7^{\circ}C$ which was $1-2^{\circ}C$ lower than on the general roadside. The average $PM_{10}$ concentration in the greenway park was $85.0{\mu}g/m^3$, a level 2-3 times lower than that at the roadside. The noise level at the greenway site was 4.4 dB(A)- 23.0 dB(A) lower than at the roadside. The average CO, $CO_2$, $SO_2$ and NOx concentrations in the greenway park were lower than at the roadside. The average phytoncide and anions concentrations in the greenway park were higher than at the roadside. Conclusions: The urban forest of the greenway park may have some impact on air quality and meteorological conditions.

광주지역 다중이용시설 54개소와 공중이용시설 15개소에 대한 입자상물질(미세먼지, 석면), 가스상물질(CO₂, CO, NO₂, HCHO, Rn, VOCs), 총부유세균의 농도에 대해서 조사하고 각 항목간의 상관성분석을 실시하였다. 미세먼지(PM10)는 실내주차장에서 평균 69.2 μg/m3로 가장 높았고, 이어서 보육시설, 대규모점포, 지하역사 순이었다. 일산화탄소는 실내주차장에서 평균 2.7 ppm으로 가장 높았고, 이산화탄소는 의료시설에서 604.1 ppm으로 가장 높았으며, 이산화질소는 실내주차장에서 0.036 ppm으로 가장 높았다. 포름알데하이드는 54개 전체시설에서 기하평균 3.6 μg/m3이었으며, 미술관은 631.8 μg/m3로 가장 높았다. 휘발성유기화합물질(VOCs)은 모든 시설에서 기하평균 24.14 μg/m3이었고, 이 중 톨루엔이 15.30 μg/m3로 가장 높았으며, 이어서 자일렌, 에틸벤젠, 벤젠, 스티렌 순으로 조사되었다. 총부유세균은 찜질방에서 평균 625.3 CFU/m3로 가장 높았고, 보육시설, 의료기관, 대규모점포 순이었다. 석면은 보육시설에서, 라돈은 미술관에서 높은 것으로 조사되었다. 보육시설에서 미세먼지와 총부유세균은 로그함수의 결정계수(R2) 0.5332로 양의 상관성을 보여주었고, 이산화탄소와 일산화탄소는 보육시설과 실내주차장에서 양의 상관성을 보여주었다. 휘발성물질간의 상관식은 모든시설에서 직선함수보다는 로그함수에 의해 잘 설명되었다. The purpose of this study is to investigate the concentration levels of particle materials (PM10, asbestos), gas materials (CO₂, CO, NO₂, HCHO, Rn, VOCs) and total suspended colony (TSC), and the correlations among these materials in indoor air quality of 54 multiple-use facilities and 15 public-use facilities of Gwangju. The highest mean concentration of PM10 was 69.2 μg/m3 at indoor parking place, followed by childcare facilities, large commercial building and subway station building. The highest mean concentration of CO was 2.7 ppm at indoor parking place and that of CO₂ was 604.1 ppm at medical service facilities. The highest mean concentration of NO₂ was 0.036 ppm at indoor parking place. The geomean concentration of HCHO was 3.6 μg/m3 in all facilities and the highest was 631.8 μg/m3 at art gallery. The geomean concentration of VOCs (5 species) was 24.14 μg/m3 in all facilities and toluene was the highest material of 15.3 μg/m3, followed by xylene, ethylbenzene, benzene and styrene. The highest mean concentration of TSC was 625.3 CFU/m3 at jjimjilbang, followed by childcare facilities, medical service facilities and large commercial building. The highest of asbestos was 0.0072 each/cc at childcare facilities and that of radon was 1.41 pCi/L at art gallery. PM10 showed positive correlations to TSC with R2 = 0.5332 by lognormal equation at childcare facilities. CO₂ showed positive correlations to CO at childcare facilities and indoor parking place. Lognormal equation fitted to the VOCs data more than normal equation in all facilities.

The aim of this study is to understand the characteristics of indoor air pollutants and provide information about the present Indoor Air Quality(IAQ) in 104 public facilities from January 2011 to December 2012. The measured air pollutants are PM10, HCHO(formaldehyde), CO, CO2, and total airborne bacteria(TAB). And the effects of environmental factors such as temperature, humidity and construction characteristics were analyzed in relation to the measured concentrations. The results of this study showed that the mean concentration of PM10, CO2, HCHO, CO, and TAB were 55.3 /, 558.6 ppm, 31.0 /, 1.2 ppm, and 561.3 CFU/, respectively. The correlation analysis showed that CO2 and HCHO (r=0.497, p<0.01), CO2 and TAB (r=0.468, p<0.01), and PM10 and CO (r=0.342, p<0.01) were significant. The result of regression analysis was found that the influence factors associated with the concentration of PM10, HCHO, and TAB were the year of building construction, the temperature and the humidity.

광주지역 기상자료를 이용하여 기온변화를 예측하고, 광주지역의 이산화탄소, 일산화탄소, 상대습도의 상관성연구를 실시하였다. 2008년까지 48년간 광주지역 전체 평균기온은 13.5℃이며, 2108년까지 100년간 2.7℃정도 증가할 것으로 예측되었다. 안면도지역에서 이산화탄소 연평균 농도는 1999년과 2008년에 각각 370.7 ppm과 391.4 ppm으로서 기온의 증가에 영향을 주었다. 1997년부터 2008년까지 광주의 평균기온은 14.2℃로 나주, 담양, 화순, 장성지역 보다 훨씬 높았다. 2108년경 광주의 봄 시작일은 1월 중순 이전, 여름의 시작일은 5월 중순, 가을의 시작일은 10월 중순, 겨울의 시작일은 12월 말경으로 전망되었다. 48년간 평균상대습도는 71.3%로 7월이 가장 높았으며, 해가 지날수록 감소하여 연도와는 반대현상을 보여주었다. CO₂와 CO는 양의 상관도(0.87)를 보여주었고, 조사기간 중 CO₂ 평균 농도는 457 ppm으로 우리나라 배경농도인 안면도의 397.3 ppm(2008)에서 보다 65.6 ppm이나 높았다. CO₂는 CO(0.87)와 상대습도 (0.48) 모두에 대하여 양의 상관성을 보여주었다. The ambient temperature and concentration of carbon dioxide in Gwangju and the reducing method of temperature, air pollutants were investigated using the atmospheric data in Gwangju. Average ambient temperature (Ta_ave) was 13.5℃ during 1961 to 2008. The temperature was predicted as increasing of about 2.7℃ in 2108 after 100 years using the trend line of regression equation. Carbon dioxide was 370.7 and 391.4 ppm at Anmyundo, in 1999 and 2008, respectively, showing proportionally increased as ambient temperature. The temperature at Gwangju, 14.2℃ during 1997 to 2008, was a little higher than at neighboring counties as Naju, Damyang, Hwasoon, and Jangsung. In Gwangju, Spring will start in mid-January of 2108, Summer in mid-May, Autumn in mid-October, and Winter in last-December. The average relative humidity in the air (RHa_ave) was gradually decreased as the temperature inversely increased. The average CO₂ was 457 ppm, which is 65.6 ppm higher than that in Anmyundo, korean background area of CO₂ in 2008. Carbon dioxide showed positive correlation, both of them, with carbon monoxide (0.87) and relative humidity (0.48).
