Objectives: Vehicular emissions are one of the main sources of air pollution in urban areas. Correlation analysis was conducted between air pollutants and traffic volume in order to identify causes of air pollution in Gwangju. Methods: Using traffic volumes and air quality monitoring data from 2002 to 2012 from nine stations (seven urban areas, two roadside areas), especially at three sites where traffic volumes were high, the correlation coefficients were obtained between air pollutants as PM-10 (particulate matter), $NO_2$, $SO_2$, CO and $O_3$ at the stations and traffic volumes near the air monitoring stations. Results: Due to traffic volume and distance between the station and the traffic road, concentrations of pollutants at roadside areas were higher than at urban areas, with the exception of $O_3$. The concentration of $O_3$ showed statistically significance with those of other gas materials as $NO_2$, $SO_2$, and CO in winter (p<0.001) and spring (p<0.05). During the period of October 7 to 20, 2012, excluding periods of yellow dust, smog and rainy season, the ratio of $NO/(NO+NO_2)$ showed the highest value 0.57 and 0.40 at Unam and Chipyeong of two roadside stations, followed by 0.35 at Nongseong with vehicular effects. The correlation coefficient between traffic volume and $O_3$, CO, $NO_2$ became higher when the data on mist and haze days were excluded, than when all hourly data were used in that period, at the three sites of Unam, Chipyeong, and Nongseong. Conclusions: Air quality showed a considerable effect from vehicles at roadside areas compared to in urban areas. Air pollutant diminishment strategies need to be aggressively adopted in order to protect atmospheric environment.

Objectives: A great number of people visit forests for their bountiful healing factors. We investigated the quantity of terpene and analyzed the correlations with meteorological and environmental factors at Mt. Mudeung in order to support public health. Methods: The terpene amounts were investigated along 11 main trails using stainless steel tube packed by Tenax TA (150 mg) and Carbopack B (130 mg) during March to November 2012. Terpene amounts of 20 species (${\alpha}$-pinene, camphene, etc.), and meteorological and environmental factors were investigated in the field. Results: Terpene of 16 species was released from the forest and total terpene amounts were 2,080 pptv at the site of Chamaecyparis obtusa, the highest among 11 sites, nearby the first reservoir on Mt. Mudeung. Terpene concentrations in the forest were nine to 23 times higher than found in urban areas. Total terpene amounts had positive correlations with temperature, humidity, carbon dioxide and oxygen (p<0.01) with $R^2$ of 0.345, 0.369, 0.591, 0.145, respectively, from April to July. Wind speed and solar radiation in the forest had a negative correlation with terpene amounts and showed statistical insignificance with p-values of 0.118 and 0.233, respectively. Conclusions: This study suggests that the amounts of terpene around Mt. Mudeung are indeed higher, so visitors may enjoy a therapeutic walk in the forest with a healing effect. These results showed the forest was very effective for improving human health.

This study was carried out to investigate the characteristics of water quality parameters in the indoor swimming pool water according to the type of disinfection. The method of disinfection has a on-site oxidant generation, sodium hypochlorite and artificial seawater electrolysis that the salt was put in the pool directly. The on-site oxidant generation and sodium hypochlorite in the disinfectant contain high concentrations of bromate and chlorate. The bromate and chlorate containing the disinfectant is the cause of detection in a swimming pool. Maximum concentration of bromate in swimming pool waters was 1.365 mg/L at on-site oxidant generation and maximum concentration of chlorate was 36.00 mg/L at sodium hypochlorite. Therefore, to reduce the concentration of bromate and chlorate in swimming pool water, it is necessary to use the disinfectant containing the less quantity of bromate and chlorate and to exchange of swimming pool water frequently.
