摘要

Poor indoor air quality can have adverse effects on human health, especially in susceptible populations: however, few studies have measured multiple pollutants in facilities for susceptible populations at a national scale in South Korea. Therefore, we measured the concentrations of indoor pollutants (fine particulate matter (PM10), CO2, airborne bacteria (AB), total volatile organic compounds (TVOCs), and formaldehyde) to determine their possible relation to other indoor environmental factors and characteristics of facilities with susceptible populations, such as hospitals, geriatric hospitals, elderly care facilities, and postnatal care centers throughout South Korea. Indoor pollutants were sampled at 82 indoor facilities, including 62 facilities for susceptible populations. Spearman's correlation, Kruskal Wallis, and Mann-Whitney analyses were used to examine the relationship among and differences between pollutants at indoor facilities and indoor/outdoor differences in PM10 concentration. There were significant correlations between indoor temperature and AB concentration (r = 0.37, p 0.01), TVOCs, and formaldehyde (r = 0.264, p 0.01). Indoor PM10 concentrations were higher than outdoor concentrations at all facilities for susceptible populations (p 0.01). CO2 might be a good indicator for predicting indoor pollutants when categorized into two levels (= 750 ppm and 750 ppm). The hazard quotient of formaldehyde was higher than the acceptable level of 1 for children under the age of eight in postnatal care centers, indicative of unsafe levels. Therefore, more depth study for exposure characteristics of formaldehyde and indoor air quality (IAQ) in postnatal care facilities as a national scale is needed for finding the children exposure levels.
