Spatial and temporal characteristics of nitrate contamination and hydrogeochemical parameters were investigated for springs and surficial and bedrock groundwaters in northeastern part of Hongseong. Two field investigations were conducted at dry and wet seasons in 2011 for 120 sites including measure...

지하수 내의 아질산염이 유아에게 끼치는 악영향은? | 지하수 내 여러 오염원 중 특히 질산성 질소는 인간활동에 의해 쉽게 지하수를 오염시키는 물질로 잘 알려져 있으며, 아질산염으로 환원되어 유아에게 청색증을 유발할 수 있다(Kim et al., 2008; Benefield et al. | |
Shapiro-Wilk normality test에서 p-value가 0.05보다 작게 나타나면 수행하는 화정은? | 질산성 질소를 포함한 수질인자들의 정규성을 검정하기위해 Shapiro-Wilk normality test를 수행하였다. 이때 검정 후 p-value가 0.05보다 작게 나타나면, 정규 모집단이 아니라는 결론을 내려 비모수 검정 법을 선택하고 더 크게 나타나면 모수 검정 법을 선택하는데, 이번 연구에서는 집단 간의 수질 인자 차이를 평가하기 위해 비모수검정 방법인 Mann-whitney U test를 수행하였다(Helsel and Hirsch, 2002). | |
대수층은 어떻게 구분되는가? | 지하수 시료 채취는 총 120개소 관정에 대해 암반대수층 71개소, 천부대수층 39개소, 용천수 10개소로 심도별 관정을 구분하여 조사를 실시하였다. 조사 지역의 대수층은 크게 충적층과 잔류토양/풍화대를 포함하는 지표부근천부대수층(이하 천부대수층; surficial aquifer)과 기반암인 편마암이나 화강암 파쇄대로 구성된 암반대수층(bedrock aquifer)으로 구분할 수 있다. 해당 지역에서는 각 층의 분포상황에 대한 자료가 없고, 기존 관정을 대상으로 조사를 진행하였으므로 굴착방법, 구경 등 관정시설규모를 고려하여 천부대수층과 암반대수층으로 구분하였으며(Kim et al. |
