구미전자산업단지에서의 카르보닐화합물 분포 특성


The density characteristics of aldehydes in Kumi electronic Industrial Complex are measured in the summer and autumn in this study. Considering the characteristics of Kumi, five representative monitoring sites in Kumi are selected. According to fair Korean odor method, samples are collected and analyzed from July 26th, 2005 to October, 10th. Investigation objects include formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, iso-valeraldehyde, n-valeraldehyde. 40 samples in summer and 45 samples in autumn are measured and analyzed, respectively. The results show that the mean concentrations in residential area and industrial area are both obey the below sequence: acetaldehyde>formaldehyde>propionaldehyde>butyraldehyde>iso-valeraldehyde>n-valeraldehyde. For acetaldehyde, its monitored concentration in industrial areas and residential areas close to industrial areas is higher than other areas. However, for formaldehyde, its concentration in the residential area 3 in tends to be higher than that in industrial areas. Based on seasons, concentrations in summer with long sunshine duration are higher than those in autumn. It can be seen that the density distribution of aldehyde in Kumi industrial complexes is closely related with the widely use of alcohol-type additives for automobiles and alcohol-type fuels. Meanwhile, most of the researches on aldehyde concentrate on capital areas or petrochemical industrial areas, taking the chance of odor prevention and control law implementing, the management scheme and reduction strategies on aldehyde ought to be carried out, which are also suitable to the enterprise characteristics in other industrial areas of this study.
