Abstract

This study investigated the effects of oil dose and soil texture on the analysis results for total petroleum hydrocarbon (TPH) in artificially oil-contaminated soils. The same amount of diesel was mixed with soils having different soil texture, and soil TPH concentrations were then analyzed for comparison. Presence of clay in the soil showed lower soil TPH analysis results than that of sand only. As the clay content was increased in the soil, the lower soil TPH concentration was obtained by incompleteness of solvent extraction. As the organic matter content in soil was increased from 5.2% to 10% (weight basis), a higher concentration of TPH was obtained by TPH analysis. However, at a higher organic content in the soil, 18%, resulted in a lower TPH concentration than those of 5.2% and 10%. Gasoline dose to the soil resulted in a significantly low TPH concentration due to the volatilization of gasoline while soil mixing and analysis. This study results would provide fundamental information either to the expectation of TPH concentration in artificially oil-contaminated soil or to estimation of oil release in the real oil-contaminated site.

토양을 유류로 오염시킬 때 토양조성 및 유류 주입량 등이 토양 TPH 분석결과에 미치는 영향을 연구하였다. 동일한 양의 경유를 조성이 다른 토양과 혼합한 후 토양 TPH를 분석한 결과 토양에 점토 및 유기물함량이 존재한다면 모래로 구성된 토양에 비해 토양 TPH 결과가 적게 얻어졌다. 점토함량이 높은 토양일수록 분석전처리 시 토양이 굳는 현상이 발생하면서 실제 값보다 적은 TPH 결과치를 나타내었다. 토양 내 유기물 함유량 변화에 따른 토양 TPH 측정실험에서 유기물 함량이 높아질수록 토양 TPH 측정농도는 증가되지만, 극히 높은 18% 유기물함량조건에서는 전처리 및 용매추출의 불확실성으로 인해 오히려 낮은 TPH 분석 결과를 보여주었다. 경유 주입량에 따른 토양 TPH 농도 변화 실험 결과 경유 주입량이 많아질수록 높은 TPH 분석결과를 나타내었다. 동일한 양의 경유와 휘발유를 주입하여 유종에 따른 토양 TPH 분석결과 휘발유는 오염 즉시 휘발하여 극히 낮은 TPH 농도를 보여주었다. 본 연구결과는 차후 인위적 유류오염 토양 제조과정에서 TPH 농도를 가늠하거나 부지 정밀조사 결과 유류 유출량 등을 예측하는데 기초자료로 활용할 수 있다.
