The purpose of this study analyzed the indoor air quality of the residents' daily exchange space and diagnosed pollutants as an on-site survey of small community facilities in rural areas. The physical survey of community facilities was conducted on the year of approval of use, housing shape, wall material, area, and the number of people staying at all times, and the pollutants in the indoor space were investigated. Fine dust (PM10), Ultrafine dust (PM2.5), HCHO, TVOC were measured for indoor air quality pollutants in community facilities. It was found that 86.3% of the buildings were built on the structure and material type of community facilities, and 65% of the facilities that were aged "more than 25 years", and the approval year for use was about 25 years old. Depending on the size of the community facilities and the number of households in the administrative district, there was a large variation, and the density of occupants using community facilities was found to be 7.6㎡/person. As a result of measuring the indoor air quality of community facilities, it was analyzed that the use of periodic natural ventilation and air purifiers was more related to indoor air quality maintenance, rather than the difference in pollutant concentration due to the physical aging relationship between old and new buildings. The concentration of fine dust was distributed between 8㎍/㎥ and 70.7㎍/㎥ of the multi-use facility maintenance standards used by the vulnerable group, and the concentration of ultra-fine dust exceeded the concentration of 36.7㎍/㎥ to 42.7㎍/㎥ in four places that exceeded the attraction standard. The pollution concentration of HCHO was between 10㎍/㎥ and 960㎍/㎥, and the concentration of 210㎍/㎥ to 960㎍/㎥ was exceeded in four places that exceeded the maintenance standard. The pollution concentration of TVOC was between 60㎍/㎥ and 3,350㎍/㎥, and the concentration of 790㎍/ ㎥ to 3350㎍/㎥ was exceeded in four places that exceeded the maintenance standard.
Abstract
The purpose of this study analyzed the indoor air quality of the residents' daily exchange space and diagnosed pollutants as an on-site survey of small community facilities in rural areas. The physical survey of community facilities was conducted on the year of approval of use, housing shape, wall material, area, and the number of people staying at all times, and the pollutants in the indoor space were investigated. Fine dust (PM10), Ultrafine dust (PM2.5), HCHO, TVOC were measured for indoor air quality pollutants in community facilities. It was found that 86.3% of the buildings were built on the structure and material type of community facilities, and 65% of the facilities that were aged "more than 25 years", and the approval year for use was about 25 years old. Depending on the size of the community facilities and the number of households in the administrative district, there was a large variation, and the density of occupants using community facilities was found to be 7.6㎡/person. As a result of measuring the indoor air quality of community facilities, it was analyzed that the use of periodic natural ventilation and air purifiers was more related to indoor air quality maintenance, rather than the difference in pollutant concentration due to the physical aging relationship between old and new buildings. The concentration of fine dust was distributed between 8㎍/㎥ and 70.7㎍/㎥ of the multi-use facility maintenance standards used by the vulnerable group, and the concentration of ultra-fine dust exceeded the concentration of 36.7㎍/㎥ to 42.7㎍/㎥ in four places that exceeded the attraction standard. The pollution concentration of HCHO was between 10㎍/㎥ and 960㎍/㎥, and the concentration of 210㎍/㎥ to 960㎍/㎥ was exceeded in four places that exceeded the maintenance standard. The pollution concentration of TVOC was between 60㎍/㎥ and 3,350㎍/㎥, and the concentration of 790㎍/ ㎥ to 3350㎍/㎥ was exceeded in four places that exceeded the maintenance standard.
