“…Our results suggest that reduced physical activity fully mediated the association between fine particulate matter and children's depressive symptoms. The significant association between fine particulate matter and physical activity that we established is similar to the findings of previous studies ( An & Xiang, 2015 ; Bae & Hong, 2018 ; Baek & Park, 2014 ; Kim et al, 2020 ; Song et al, 2009 ; Yu et al, 2017 ). Warning people not to go out when levels of fine particulate matter are high may affect decisions regarding physical activity ( Wen et al, 2009 ), which in turn may have an adverse impact on children's depressive symptoms.…”

Rationale Exposure to fine particulate matter has adverse effects on mental health outcomes. However, no empirical study has yet been conducted on mechanisms of how and why exposure to fine particulate matter can affect mental health outcomes, especially focusing on children. In addition, children living in poverty may be more vulnerable to fine particulate matter. Objective This study aims to examine whether physical activity can explain the impact of ambient fine particulate matter on depressive symptoms among Korean children and whether family poverty moderates the associations between fine particulate matter, physical activity, and children’s depressive symptoms. Methods Children and their primary caregiver data were drawn from the Children’s Happiness Life Time Survey data collected by Child Fund Korea, and fine particulate matter data were derived from Air Korea, collected by the Korea Environment Corporation. Individual-level data were linked to a nationwide neighborhood-level data on air quality. Multilevel structural equation modeling was used to consider the hierarchical data structure. The analytical sample consisted of 4,161 children living in 79 neighborhoods. Results The findings suggest that living in neighborhoods with higher levels of fine particulate matter is associated with a decrease in physical activity, which in turn increases children’s depressive symptoms. Physical activity fully mediates the association between fine particulate matter and children’s depressive symptoms. However, family poverty does not have a significant moderating role for the associations between fine particulate matter, physical activity, and children’s depressive symptoms. Conclusions The results of this study indicate the importance of physical activity in relation to fine particulate matter and children’s depressive symptoms.

“…For the design guidelines and for suggesting the proper level of activities in indoor physical spaces and the correlations between activity types, the number of people, the space, the activity time, and the CO 2 concentration were derived in order to maintain a CO 2 concentration in indoor space below 1000 ppm. If the indoor physical spaces were operated using these correlations, the indoor-air-quality environment was affected positively and enhanced the effectiveness of student physical activities and the indoor occupants' health [9][10][11].…”

“…In addition, a high incidence of respiratory diseases was observed among the residents in Incheon, which exhibits a relatively high concentration of air pollutants [8]. Children are more vulnerable to the adverse effects of fine dusts compared to adults owing to their body structure, behavior, and developmental characteristics [9]. Furthermore, the "High-concentration Fine Dust Response Manual for Protection of the Vulnerable Class" describes that infants and children inhale more air pollutants than adults because of their higher respiratory rate per unit weight [10,11].…”

Owing to the recent increase in the number of warning reports and alerts on the dangers of fine dusts, there has been an increasing concern over fine dusts among citizens. In spaces with poor ventilation, the occupants are forced to open the window to initiate natural ventilation via the direct introduction of the outside air; however, this may pose a serious challenge if the external fine-dust concentration is high. The lack of natural ventilation increases the indoor carbon dioxide (CO2) concentration, thus necessitating the installation of mechanical ventilation systems. This study analyzed the frequency of the application of mechanical ventilation systems in the Multi-purpose activity space of elementary schools, which are spaces where children require a higher indoor air quality than adults owing to the rapid increase in the CO2 concentration of the Multi-purpose activity space during activities. In addition, the architectural and equipment factors of the Multi-purpose activity spaces of nine elementary schools were characterized. The results revealed that five out of the nine elementary schools installed mechanical ventilation systems, whereas the remaining four schools installed jet air turnover systems. The indoor air quality of the Multi-purpose activity space of D elementary school, which had the minimum facility volume among the schools investigated in this study (564.2 m3), with up to 32 participants for each activity, was investigated. The results revealed that the ultrafine-dust (PM2.5) concentration of the facility was as high as 4.75 µg/m3 at a height of 1.2 m, and the CO2 concentration was as high as 3183 ppm. The results of the analysis of three elementary schools with different volumes were compared and analyzed using CONTAM simulation. This study determined the required volume per occupant and the optimum number of occupants for a given volume and presented guidelines for the optimum number of occupants, activities, and volume to reduce the high concentration of pollutants in the analyzed Multi-purpose activity space. The guideline proposed in this study is aimed at maintaining the CO2 concentration of the Multi-purpose activity space below 1000 ppm, as prescribed by the Indoor Air Quality Control in Public-Use Facilities, Etc. Act in South Korea.

The purpose of this study was to empirically confirm that the Taebaek Mountains are one of the primary causes of the spatial difference in the concentration of particulate matter between the west (Yeongseo) and east (Yeongdong) sides of the mountain range in Gangwon Province in the Korean peninsula. We investigated the effects of the Taebaek Mountains by analyzing data on PM10 and PM2.5 concentrations, wind direction, and wind speed, collected over seven years from 2015 to 2021 in the Yeongseo and Yeongdong regions. Our results demonstrated that wind direction and speed could be considered significant features in the aerial transport of PM10 and PM2.5. When the concentrations were higher than normal, the reduction effect of the Taebaek mountain range on PM10 was clear, while the effect on PM2.5 was not as obvious. When wind blows from west to east across the Taebaek Mountains, the wind speed may increase on the Yeongdong; in these cases, the concentrations of PM10 and PM2.5 were much lower than at the Yeongseo. Moreover, with these westerly winds, when the wind speed at Yeongseo exceeded 2 m/s, the distribution range of high concentrations of PM10 and PM2.5 was narrower at Yeongseo and Yeongdong than when the wind speed was weaker.
