The Evolving Roles of Electrical Geophysical Methods for In Situ Remediation Assessment: Progress and Perspectives

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract In situ remediation of contaminated soil and groundwater demands real‐time monitoring to capture complex subsurface dynamics. Geophysical methods, particularly electrical resistivity tomography (ERT) and induced polarization (IP), offer non‐ or minimally invasive, high‐resolution imaging of subsurface changes during remediation.

Assessment of the impact of benzene, toluene, ethylbenzene, and xylene (BTEX) on soil microbial population in selected areas of Port Harcourt City, Nigeria

Scientific African
Human activities are on the rise in these areas and consequently, the discharge of BTEX to the environment is on the rise. Benzene, toluene, ethylbenzene, and xylenes (BTEX), are known to cause cancer and mutagenesis.

Intermittent Soil Vapor Extraction (SVE) for VOC Removal: A Full‐Scale Case Study

Remediation Journal, Volume 36, Issue 3, Summer 2026.
ABSTRACT The present study investigates the field‐scale application of a soil vapor extraction (SVE) system operated under intermittent conditions for the remediation of an industrial site contaminated with ethylbenzene and xylenes. The contamination, originating from a release from an underground storage tank, affected the entire thickness of the ...

State of the Practice − Sub‐Aqueous In‐Situ Solidification for Contaminated Sediment Remediation

Remediation Journal, Volume 36, Issue 4, Autumn 2026.
ABSTRACT In‐situ solidification (ISS) has emerged as a cost‐effective and versatile technology for sediment remediation, particularly for addressing contamination at greater sediment depths. This paper evaluates ISS in the context of conventional sediment remediation approaches, highlighting its advantages, design and implementation considerations, and

Anaerobic degradation of BTEX in a packed-bed reactor

Water Science and Technology, 2002
A bench-scale horizontal-flow anaerobic immobilized biomass (HAIB) reactor was assayed aiming to verify its performance in degrading benzene, toluene, ethylbenzene and xylene (BTEX). A 138-ml HAIB reactor filled with polyurethane foam matrices containing immobilized anaerobic biomass was initially fed with synthetic substrate containing protein ...

Health risk assessment of exposure to volatile organic compounds (BTEX) in a painting unit of an automotive industry

بهداشت و ایمنی کار, 2018
Introduction: Adverse effects of volatile organic compounds (VOCs) including general and specific effects like carcinogenic of benzene are well known. The aim of this study was to evaluate occupational exposure to BTEX compounds in the painting unit of ...

Salt‐Freshwater Mixing and Submarine Groundwater Discharge in Sloping Unconfined Tidal Aquifers

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Previous studies have revealed the groundwater flow and salt transport in unconfined coastal aquifers in response to numerous factors. However, previous studies assumed a flat aquifer base, and it is unclear how a sloping aquifer base would affect the subsurface flow and salinity distributions.

BTEX Content of Marine Surface Sediments Used as Indicators of Marine Oil and Gas

Yankuang ceshi, 2013
A number of studies indicate that the anomaly of BTEX content in core and sediments samples are valuable oil and gas geochemical exploration indicators. This anomaly with high-resolution, high precision was directly related to oil and gas reservoirs.

Phytoremediation of BTEX contaminated soil by Canna×generalis

Ecotoxicology and Environmental Safety, 2011
Bioaccumulation experiments showed that the canna (Canna×generalis) could accumulate BTEX (benzene, toluene, ethylbenzene and xylenes) from root zone and rhizome zone soil and translocate these compounds to the shoot. A comparison among these compounds showed that the sequences for accumulation in the root, rhizome and shoot were strongly related to ...

The ecology of anaerobic degraders of BTEX hydrocarbons in aquifers [PDF]

FEMS Microbiology Ecology, 2016
The degradation of benzene, toluene, ethylbenzene and xylene (BTEX) contaminants in groundwater relies largely on anaerobic processes. While the physiology and biochemistry of selected relevant microbes have been intensively studied, research has now started to take the generated knowledge back to the field, in order to trace the populations truly ...
