Abstract

This study was carried out to assess the distribution and pollution level of organic matters and nutrients in surface sediments of the Yeongsan River Basin. The surface sediments were collected from the mainstream (12) and tributaries sites (4) for two years from 2015 to 2016, and the particle sizes, organic matters (Ignition Loss, COD, TOC) and nutrients (TN, TP, SRP) were analyzed. The distribution of particle sizes was dominated by sand in the upstream sites (MS1-MS7) and by silt loam in the downstream sites (MS8-MS12), but MS3 and MS6, located slightly upstream of the two weirs, were found to be mostly loamy sand and silt loam, respectively. As a results of the correlation assessment, the organic matters (IL, COD, TOC) were strongly correlated with particle sizes, while the nutrients (TP, SRP) were weak except for TN. The concentrations of organic matter and nutrient were higher at the downstream and the sites nearby the two weirs (MS3, MS6). In particular, the TP concentration at the MS3 site sampled in the second half period of the years was higher than that in the first half periods. Comparing of sediments criteria, the organic matters and nutrients were evaluated to have almost no toxic effects at all sites.

본 연구는 영산강 수계에 위치한 하천의 표층 퇴적물 중 유기물과 영양염류들의 농도 분포와 오염도를 평가하기 위하여 수행하였다. 표층 퇴적물 시료는 2015년부터 2016년까지 2년 동안 하천 중 본류 12개 및 지류 4개 지점으로부터 채취하여 입도와 유기물(Ignition Loss, COD, TOC) 및 영양염류(TN, TP, SRP)를 분석하여 평가하였다. 입도 분포는 상류와 하류로 구분하여 모래와 양질사토가 우세하였으나, 상류에 보가 설치된 MS3와 MS6 지점의 경우 각각 양질사토와 미사양토로 나타났다. 상관성 평가 결과, 유기물 항목들은 입도들과 강한 상관관계를 보인 반면 TN을 제외한 영양염류 항목들은 약하게 나타났다. 유기물 및 영양염류 농도의 분포 특성은 상류보다 하류 그리고 보가 설치된 지점들에서 높았고, 특히 MS3 지점의 TP 농도는 상반기보다 하반기에 높은 특성을 보였다. 국내외 오염기준과 비교 평가한 결과, 유기물 및 영양염류 항목들은 전 지점들에서 심각한 오염상태가 아닌 것으로 평가되었다.
