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.

The purpose of this study is to investigate the relationship of fine dust PM<sub>10</sub> and heavy metals in PM<sub>10</sub> in Asian dust flowing into Gwangju from 2013 to 2018. The migration pathways of Asian dust was analyzed by backward trajectory analysis using HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory) model, and the change of heavy metal concentration and heavy metal content per 1 ㎍/㎥ of fine dust PM<sub>10</sub> in Gwangju area were analyzed. Also, the characteristics of the heavy metals were analyzed using the correlation between the heavy metals in PM<sub>10</sub>. As a result of analyzing Asian dust entering the Gwangju region for 6 years, the average concentration of PM<sub>10</sub> measured in Asian dust was 148 ㎍/㎥, which was about 4.5 times higher than in non-Asian dust, 33 ㎍/㎥. A total of 13 Asian dust flowed into the Gwangju during 6 years, and high concentration of PM10 and heavy metals in that were analyzed in the C path flowing through the Gobi/Loess Plateau-Korean Peninsula. As a result of the correlation analysis, in case of Asian dust, there was a high correlation between soil components in heavy metals, so Asian dust seems to have a large external inflow. On the other hand, in case of non-Asian dust, the correlation between find dust PM<sub>10</sub> and artificial heavy metal components was high, indicating that the influence of industrial activities in Gwangju area was high.
