Author(s): Han Zhang, Shujia Ke, Shihong Zhang, Jingai Shao, Hanping Chen Cadmium (Cd) pollution in soil has attracted more attention recently for its high toxicity and easy accumulation in crops. This study aims to investigate the mechanisms governing the transport behavior of Cd, and to simulate and predict the long-term migration of Cd in different paddy soil layers. Therefore, a layer-by-...

Author(s): Sudhakar Singha, Srinivas Pasupuleti, Soumya S. Singha, Suresh Kumar Globally, groundwater heavy metal (HM) pollution is a serious concern, threatening drinking water safety as well as human and animal health. Therefore, evaluation of groundwater HM pollution is essential to prevent accompanying hazardous ecological impacts. In this aspect, the effectiveness of various groundwater HM...

Author(s): Michael J. Schmidt, Stephen D. Pankavich, Alexis Navarre-Sitchler, Nicholas B. Engdahl, Diogo Bolster, David A. Benson Geochemical systems are known to exhibit highly variable spatiotemporal behavior. This may be observed both in non-smooth concentration curves in space for a single sampling time and also in variability between samples taken from the same location at different times....

Author(s): Alice Kimie Martins Morita, Natalia de Souza Pelinson, Vagner Roberto Elis, Edson WendlandAbstractEven though attenuation processes in the subsurface are known to reduce the impacts of contaminant plumes, their importance is significantly dependent on geological and climatic characteristics, as well as on the leachate quality. The knowledge of attenuation processes linked to different...

Author(s): Wei Tao, Changgen Mei, Nurhidayah HamzahAbstractSurfactant solutions have been frequently studied for soil remediation. However, since they are expensive, massive consumption of surfactant solution can constrain their application. Surfactant microbubbles, or colloidal gas aphrons (CGAs), can serve as cost effective alternatives of surfactant solution because the use of CGAs reduce the...

Author(s): Abdorreza Vaezihir, Mohammad Bagher Bayanlou, Zeinab Ahmadnezhad, Ghodrat BarzegariAbstractAdsorption is a well-known phenomenon that causes the remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylene). Zeolite is typically useful for the removal of BTEX from groundwater. In this study, the migration of the BTEX plume was investigated in a bench-scale tank model as a shallow...

Author(s): Javier VilcáezAbstractExperimental results on barium transport in dolomite are used to formulate, calibrate, and validate a reactive transport model of produced water disposal into dolomite saline aquifers. The model accounts for sorption, dissolution/precipitation reactions of minerals (dolomite, calcite, barite, gypsum, and witherite) and complexation and acid-base reactions of most...

Author(s): Obiri-Nyarko Franklin, Kwiatkowska-Malina Jolanta, Malina Grzegorz, Wołowiec KrzysztofAbstractColumn experiments were performed to assess the effectiveness of zeolite and compost-zeolite mixture in removing dissolved lead (Pb2+) from acidic water of pH 2.4. The acid neutralizing ability and hydraulic performance of the materials were also studied. Fitting the advection-dispersion...

Author(s): Xiaolin Kuang, Jihai Shao, Liang Peng, Huijuan Song, Xiangdong Wei, Si Luo, Ji-dong GuAbstractBiological soil crusts (BSCs), which are ubiquitous in paddy fields, are known to remove pollutants from paddy fields systems. The Nano-TiO2 enhanced the removal of Cd(II) by BSCS under acidic irrigation water was found, and its mechanism was investigated. After the addition of nano-TiO2, the...
