Understanding the fate of contaminants in heterogeneous aquifer systems is crucial to explain their transport behavior. Although it has been proven that heterogeneity a significant control over quantification these processes, extent this impact yet be studied. The unique contribution work lies assessment field-scale physical and chemical modeling reactive processes subsurface. main objective study investigate understanding biogeochemical subsurface environment, coupled with advective...
Arsenic contamination in drinking water is a pressing global issue, with over 250 million individuals lacking access to that meets the World Health Organization's recommended limit of 10 µg/L. Arsenic, confirmed carcinogen, poses significant health risks, necessitating efficient and cost-effective removal strategies. Adsorption remains one most prevalent methods for arsenic removal, employing materials such as metal oxides, graphene-based nanocomposites, carbonaceous...
Nanomaterials have attracted much attention in recent decades for contaminant remediation purposes, due to their unique physical properties such as high surface area per unit volume, the ability process functional groups on surfaces target specific pollutants, and adjust characteristics size, morphology, porosity, chemical composition according need. Among nanomaterials, zero-valent iron, iron oxides, manganese activated carbon, carbon nanotubes graphene been most commonly used. these...
Arsenic is one of the most common toxic heavy metals that found in groundwater, and it a contaminant encountered water resources. Conventionally, Zero-Valent Iron (ZVI) utilized by various mechanisms for treatment arsenic. ZVI material characterized as having high adsorption capacity availability; characteristics make an efficient reactive reagent. In comparison, rising alternative media based on graphene its derivative nanomaterials, such magnetite-reduced oxide (MrGO), are less...
As surface waters become more polluted, many communities around the world need to turn groundwater resources for their drinking water needs. Groundwaters on other hand, carry risk of having geogenic arsenic (As) that is at hazardous levels human health. legislated by governments in recent years a maximum concentration 10 ppb as recommended World Health Organization since 1991. This has caused surge research related removal from waters.Using adsorptive materials, among alternatives stand out,...
Uraninite (UO2) is the most desirable end product of in situ bioreduction because its low solubility under reducing conditions. For effective long-term immobilization uranium (U), there should be no biotic or abiotic reoxidation insoluble biogenic U(IV). It therefore critical to understand stability U(IV) oxic- and nutrient-limited conditions at U-contaminated subsurface sites. has now been established that following bioremediation U(VI) via nutrient addition subsurface, a range physical,...
Heavy metals can significantly affect the kinetics of substrate biodegradation and microbial growth, including lag times specific growth rates. A model to describe metabolic as a function history concentration has been previously described by Wood et al. (Water Resour Res 31:553-563) Ginn 35:1395-1408). In present study, this is extended effect heavy on developing an inhibitor-dependent functional account for state microorganisms. The inhibiting metal explicitly incorporated into functional....
Abstract BACKGROUND: Microbial behavior in batch reactors may be different from that continuous flow reactors, which is expected to affect microbial response heavy metal exposure. Four parallel and growth tests were used investigate the single joint toxicity of Zn Cu Artrobacter sp. JM018. RESULTS: The results indicated more toxic than under all conditions. In concentrations showed a stimulatory effect on growth. However system, 125 µmol L −1 exposure produced inhibition. case mixed...
