| Abstract |
Archives are the indoor spaces which have the special purpose of preservation of records. But the values of the Korean standard about air quality in archives are not realistic. Furthermore there are no measured data for analysis about indoor air quality level of archives. So, we measured indoor air quality of three archives on site for evaluation standard level. We carried comparative analyses of the Korean standard and ISO-11799 the international standard for review of the adequacy of standard. SO2, O3 and CO concentration levels in archives were much lower(about 10% level) than the Korean standard. PM10 and Formaldehyde concentrations were about 40% level of the Korean standard, and NOx was about 65% level. But, TVOCs concentration was exceed the standard value(400 μg/m3). Temperature and Relative humidity level were far off the standard range. SO2, O3 and CO standard values should be improved to the international standard levels for realistic regulation values. NOx and Formaldehyde regulation values in the Korean standard should be gradually improved to the international standard levels, and their concentration management methods should be researched at the same time. As TVOCs concentration levels were exceed the standard, it is necessary to control the indoor air quality more strictly. The thermo-hygrostat must be installed to control temperature and humidity in archives. |
