개요
A study on fugitive dusts was conducted at Saemangeum reclaimed land located in Kimje area. The monitoring result on the fugitive and suspended dust was significantly affected by the farming activities(harvesting and land cultivation) and vehicles passing nearby the measuring points. The concentration of the fugitive dust generated from the reclaimed land was reduced remarkably by effect of halophyte present on the ground and the tide embankment. Comparing to the data collected in 2006 and 2007, the concentrations of TSP and PM10 were decreased by 47.4% and 54%, respectively. After harvesting operations at paddy field, TSP was increased by 22% while PM10 by 54%. The concentration of a Clwhich is a representative ion of sea-salt was decreased to about 35% in 2007 when compared to 2006. This represents that the inside area change and plant covering rate effect on the decrease of fugitive dust. The
results that the correlation analysis for the compounds of the topsoil at each measuring point shows that near the coastline is more comparable. The canopy of halophyte in the source area also increased which reduced the fugitive dust remarkably. The dust distribution measured by dust spectrometer at the same point shows that, most particles are 0.5㎛ to 2um size but not greater than 5㎛
