This study aimed to evaluate the indoor air quality differences at 19 indoor play centers of cafés and play areas in Gyeonggi-do where were 430 ㎡ or larger. We examined concentrations of formaldehyde (HCHO), volatile organic compounds (VOC), particulate matter, and total airborne bacteria, and how their distributions varied with the number of visitors at the places. On weekdays, there were no statistically significant differences in mean indoor air pollutant concentrations between the cafés and play areas at 95% confidence intervals. However, significant differences were observed on weekends when the number of visitors increased. HCHO concentrations increased up to 159%, and VOC concentrations increased up to 210%. A higher increase rate of HCHO occurred at the cafés compared to the play areas since cooking operations were performed under natural ventilation. The PM10 concentration increased by approximately 33.2%, with an increase of 49.2% in the play areas and a 18.3% increase in the cafés on weekends. PM2.5 concentration particularly increased during weekends in the cafés and play areas by 113% and 63.6%, respectively. During cooking operations, the concentration of gaseous and particulate pollution increased more in the air pollutant concentration of cafés, and the overall bacterial concentration increased during weekends due to higher numbers of visitors. Therefore, indoor play centers with cooking operations require adequate air quality management to mitigate the indoor pollution.

This study was conducted to evaluate the effects of soil amendments on arsenic (As) bioavailability in As-polluted soils. We determined the subsequent changes in As toxicity toward earthworms (Eisenia fetida) and As uptake by earthworms. We also investigated whether As bioaccumulation could be used as an index to evaluate changes in quality of As-polluted soils. No significant changes in acute toxicity to earthworms were observed, and the observed increases (70-93 mg kg-1) or decreases (27-38 mg kg-1) in bioavailable As in soils at the end of test were not related to the As concentrations in earthworms. The As concentration in earthworms 14 days after exposure was significantly lower in calcium superphosphate (CSP)- and S-treated soils (101.4-112.8 mg kg-1) than in control soil (138.9 mg kg-1), probably owing to reduced earthworm growth due to lower pH in CSP- and S-treated soils (6.3-7.3) relative to control and steel slag-treated soils (7.5-8.4). Comparisons of As toxicity and the effects of soil properties on this toxicity toward various species of earthworms could facilitate the use of earthworms to produce biological indices for evaluating changes in quality of As-polluted soils following amendment treatments.

Phytoncide, a forest healing indicator, is known to help suppress depression, anxiety, and stress of human. Furthermore, it has positive effects on blood pressures, pulses, and mood fluctuations. Previous studies mostly focused on phytoncide emission trends and its concentration prediction in forest. Moreover, a direct comparison of phytoncide concentrations between existing studies is often challenging owing to the use of differingunits, target analytes, analysis conditions, as well as unreported concentrations per type of the compound. Therefore, this study evaluated the overall performance of adsorption sampling and thermal desorption coupled with gas chromatography to evaluatethe phytoncide concentration in a forest atmosphere. To this end, the analysis quality management and analysis accuracy were evaluated for on-site samples in two different laboratories. The phytoncide analysis results obtained from each laboratory can serve as reference data for the adsorption capture-thermal desorption method applied to biogenic volatile organic compounds.

In 1970s, the Korean government formulated an energy saving plan, and in 1990s, they added items while implementing the efficiency rating and labeling system. According to the data released by the International Energy Agency (IEA), by 2050, energy savings by the equipment and facilities sector would account for 36% of the policy measures for greenhouse gas reduction. As such, the most useful way to reduce greenhouse gas emissions is to increase the original energy efficiency by distributing various energy-saving products through the efficiency management system. High-efficiency energy equipment certification is a system that certifies products that meet a certain standard in order to promote the supply of high-efficiency energy equipment. In the case of aeration devices, the performance and efficiency of air diffusers can be continuously managed to reduce national energy and carbon dioxide emissions. The purpose of this study is to confirm the definitive carbon reduction levels in the relevant field by examining the performance-based appropriate energy efficiency of air diffusers in aeration tanks during sewage treatment.
