Volatile Organic Compounds(VOCs) in municipal wastewater are hazardous pollutants
to humans and the environment. They are discharged from numerous sources and
wastewater treatment plants are a major concern for source control policies. In this study,
the occurrence and characteristics of 17 VOCs(1,1-Dichloroethylene, 1,2-Dichloroethane,
1,1,1-Trichloroethane, Bromoform, Carbon tetrachloride, Chloroform, Dichloromethane,
Vinyl Chloride, Trichloroethylene, Tetrachloroethylene, Benzene, Toluene, Ethylbenzene,
Xylene, Styrene, Naphthalene, and Acrylonitrile) in municipal wastewater of Seoul
between 2018∼2020 were investigated. As a result, several cases of violations of the
standards and unauthorized discharge were observed. Chloroform and dichloromethane
were the primary VOCs emitted into wastewater and their sources were mostly hospitals
and laboratories. VOCs in wastewater from dye plants and car washing facilities were
more varied than expected. Therefore more specific monit
