Arsenic (As) contamination threatens public health as it migrates from soil surface to groundwater through the vadose zone. The attenuation factor (AF), defined ratio of initial As concentration maximum reaching groundwater, quantifies retention in While U.S. Environmental Protection Agency recommends a default AF value 1, this approach overlooks site-specific capacity soils, potentially overestimating contamination. To improve risk assessment, tailored datasets for that consider local...
For the upcoming ubiquitous computing environments in u-health areas involve measurement of physiological signals daily life. However, those signals, such as photoplethysmorgraphy (PPG), and electrocardiogram (ECG), requires being still tight during order to get accurate result preventing noises caused by casual movement. In this paper, we propose a method obtain situation where little movement is allowed. By measuring PPG motion at forehead motion, calibrate distorted signal with signals....
The water and oxygen contents of the vadose zone change cyclically depending upon meteorological condition (e.g., intermittent rainfall), which can affect biogeochemical reactions that govern fate arsenic (As). To simulate evaluate transient behavior As in this when subjected to repeated wet dry conditions, soil column experiments with different properties were conducted. Three wetting-drying cycles resulted fluctuation dissolved contents, consequently, reduction-oxidation potential columns....
The nonstationary nature of water and oxygen content in the vadose zone determines various biogeochemical reactions regarding arsenic (As) therein, which affects groundwater vulnerability to As contamination at a site. In present study, we evaluated effect soil organic matter (OM) on behavior using specifically designed columns that simulated zone. Three wet-dry cycles were applied each four with different OM contents bulk densities. was found exhibit variable effects, either inhibiting or...
The migration of petroleum hydrocarbons in vadose zone involves complex coupled processes such as downward displacement and natural attenuation. Despite its significance determining groundwater vulnerability to contamination optimizing the remedial strategy, it has not been comprehensively studied terms overall under field-relevant conditions. In this study, a series unsaturated soil column experiments were conducted by simulating subsurface diesel within using different textures at bulk...
Acid or alkali spills destroy the physicochemical properties of soils and cause irreversible damage to their ecological functions. This study examined changes in (i.e., organic matter, clay content, cation exchange capacity (CEC)) as well pH buffering (indicator soil function) 20 field response spills. Also, we identified characteristics vulnerable Although did not substantially change matter decreased by approximately 50%, consequently resulting a 41% decrease capacity. When classified into...
Abstract Cadmium is a nonessential heavy metal and well‐known persistent environmental pollutant. I causes variety of toxic effects, including immunotoxicity. The exact mechanism its cellular effects still unclear. Cell‐cycle regulation an important factor that modulates cell death; however, cadmium‐mediated cell‐cycle arrest leading to death in murine macrophages has not been investigated. at 20 μM induced both apoptotic necrotic macrophage (J774A.1) cultures 24 h. triggered re‐entry G0/G1...
