초록

The construction equipment is one of the major sources for hazardous air pollutants in Korea, and the its managementhas been of great concern recently. The objective of this study was to estimate each contribution of emissionof construction equipments according to their production year, electric power consumption and type. To achievethis goal, we developed pollutant emission factors for the machineries manufactured after 2009, which are excludedfrom the present framework of Korean air pollutants inventory, CAPSS. More than 800 data obtained fromemission investigations were utilized for the estimation. Compared with the previous estimation, the scheme usedthis study was modified to incorporate new emission factors as well as to include the corresponding activity data.
Such improvement allow us to gain more detailed emission informations which are better characterized by specificationsof construction equipments. The total amount of pollutants emitted from construction equipments in 2011were estimated as 126.8, 7.0, 58.3, and 17.0 kton for NOx, PM, CO, and VOC, respectively. The estimation resultsindicate that the increase in the emission of equipments is significantly related to their age and power consumption.
The emissions of the older ones manufactured from 1992~1996 were estimated to be the contribution ranged from23.7% to 26.8%, whereas the newer ones (2009~2011) showed the attributions of 11.3~21.5%. In addition, theresults show that the emission of each equipment was increased with the increase in the electric power consumptionof engine, probably due to their average output power. Among the nine types of machinery compared, excava-tors and forklifts were investigated to contribute relatively higher emissions in the level of 39.8~44.0% and 32.0~34.2%, respectively.
