XAD 수지분획에 의한 용존유기물질 특성 연구

다국어 초록 (Multilingual Abstract)

Changes in the characteristics of dissolved organic matter was studied at selected stations in the Nakdong river basin using physical and chemical mothods. Characteristics of dissolved organic matters were analysed and assessed. Production of disinfection byproducts were also investigated. Distribution of the organic compounds according to the Molecular weight(㎿) indicate that ㎿s higher than 100K were highest with cattle excrement wastewater and ㎿ between 100-10K were highest with waters from forest streams. Low ㎿ compounds (less than 1K) were highest with the effluents from environmental facilities. Results of resin fractionation study show that acidic hydrophobic substances(AHS) were dominant in many stations. The values were higher in the samples from mainstreams and sidestreams where the influence of organic matter is higher than the water from environmental facilities. Hydrophilic neutral substances(HoN) such as hydrocarbon, pesticides and detergents were higher in the wastewater treatment facilities. HoN values of water from the forest streams were 4.7% indicating there is no synthetic pllutant.
