Broad scale monitoring of estrogenic compounds was performed at 19 sampling points throughout the Yeongsan and Seomjin river basins 5 wastewater treatment plants (WWTPs) adjacent to Gwangju area, Korea, from December 2005 August 2007. The concentrations compounds, including estrone (E1), 17β-estradiol (E2), 17α-ethynylestradiol (EE2), bisphenol-A, nonylphenol (NP) 4-octylphenol (OP), in samples measured with gas chromatography/mass spectrometry (GC-MS). In addition, activities were...
Exposure to heavy metals such as lead, cadmium, and mercury poses serious health risks pregnant women because of their high toxicity. In this study, we investigated the associations metal exposure with birth outcomes Korean infants. Data 5,215 between 2015 2019 were analyzed. This study was part Children's Environmental Health (Ko-CHENS) study. Linear regression logistic analyses used examine effects concentrations on weight, small for gestational age, large age after adjusting maternal...
The objective of this study was to characterize the effects organic soil amendment (compost) on bacterial populations associated with petroleum hydrocarbon (PH) degradation and nitrous oxide (N2O) dynamics via pot experiments. Soil artificially contaminated diesel oil at total (TPH) concentration 30,000 mg·kg-soil-1 compost mixed a 1:9 ratio (w/w). Maize seedlings were planted in each ten pots two treatments (compost-amended unamended) prepared. experiment conducted for 85 days....
The complexation reaction between Cu and four targeted endocrine-disrupting compounds (EDCs)-17beta-estradiol (E2), 17alpha-ethynylestradiol (EE2), 4-octylphenol (OP), bisphenol A (BPA)-was studied using the fluorescence quenching method, with changed EDC forms evaluated for their estrogenic activities an E-screen assay. results of showed no activity Cu, whereas EDCs indicated high cell proliferation (decreasing order induction: E2, EE2, OP, BPA). response FTIR (Fourier transformation...
Abstract Compost is widely used as an organic additive to improve the bioremediation of diesel-contaminated soil. In this study, effects compost amendment on remediation performance, functional genes, and bacterial community are evaluated during soils with various ratios (0–20%, w/w). The study reveals that diesel removal efficiency, soil enzyme (dehydrogenase urease) activity, CH 4 oxidation potential, N 2 O reduction potential have a positive correlation ( p < 0.05). denitrifying genes...
본 연구에서는 Hack의 이론과 형상계수를 적용하여 소하천 유역의 지형학적 특성을 파악하였다. 이를 위해 유역면적과 유로연장을 군집분석을 통해 분류하고 이론에 근거하여 규모별 거동특성 지수를 산정하였다. 아울러 유역형상을 파악하고, 형상계수가 설계홍수량 산정시 국내에서 주로 적용하고 있는 경험식과의 관계성을 검토하였다. 그 결과 h와 국내의 소하천은 정사각형 유역형상에 가까운 직선하천임을 확인하였다. 소하천의 홍수량 산정을 위한 경험식을 검토한 집중시간과 저류상수와 관계는 1.37의 관계를 갖으며, Russel 경험식 <TEX>${\alpha}$</TEX>는 0.73으로 분석되었다. 이는 저류상수의 경우 유역이 중 대규모 유역과 비해 상대적으로 작게 산정됨을 의미한다. 향후 유역에 대한 강우-유출 해석 및 추가적 유역특성분석이 수행된다면 국내 적합한 개발이 가능할 거라 판단된다. In this study, the topographical characteristics of...
