The Concentrations of Ambient VOCs at Industrial Complex Area in Daegu City

Abstract

This study was carried out to characterize the ambient VOCs concentrations of industrial complex in Daegu city. VOCs concentrations of industrial complex area appeared to be higher than those in the non-industrial complex area as following order toluene > ethylbenzene > m,p-xylenes > o-xylene but benzene and chloroform were similar to each other sites. There was seasonal variation of VOCs concentrations in the industrial complex area, higher in summer and lower in winter. In particular the industrial complex area shows that higher on weekday than weekend and higher in the daytime than in the morning or nighttime because industrial complex area influenced by the chemicals. Correlation coefficients among VOCs were confirmed that VOCs of industrial complex area were more related to each other than those of non-industrial complex area and VOCs concentrations have shown generally negative correlation with wind speed.

An outbreak of neurologic symptoms among patients exposed to an unknown stench in a high school near an industrial complex: an epidemiological investigation

“…Among air sampling data, MEK was detected relatively frequently from both industrial complexes and schools, and this could indirectly show that schools are affected by pollutants emitted from industrial area. Also, it is reported that the concentration of heavy metals-such as nickel and cadmium [33]-and VOCs-such as toluene, ethylbenzene, and xylene [34]-is higher in the vicinity of the "Daegu Third Industrial Complex " than in other regions of Daegu.…”
