Electronic Smoking Devices Among University Students: Usage Patterns and Chemical Composition of Inhaled Substances

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT This study investigated the prevalence of electronic smoking device (ESD) use and its associated behavioural and chemical risks among university students in Bahia, Brazil. A cross‐sectional survey was conducted with 355 students from public and private institutions through an online questionnaire between April and May 2023. Among participants,

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.

3D‐Printed Optical Volatile Organic Compound Sensors Based on Donor‐Substituted Coumarin Thermally Activated Delayed Fluorescence Emitters

Small Science, Volume 6, Issue 6, June 2026.
Donor–acceptor coumarin emitters displaying thermally activated delayed fluorescence (TADF) are formulated into photocurable resins and processed by digital light processing (DLP) 3D printing. The resulting printed materials show a sensitive and repeatable photoluminescence response when exposed to volatile organic compounds (VOCs).

Demonstration of a High‐Resolution Passive Profiler for Characterizing the Distribution of PFAS in Groundwater: A Comparison of Methods in the Field

Groundwater Monitoring &Remediation, Volume 46, Issue 3, Page 38-54, Summer 2026.
Abstract Characterizing the concentration and mass flux spatial distributions at sites with complex hydrogeologic conditions is critical to evaluate the fate and transport of contaminants, as well as to design effective remediation programs. PFAS (per‐ and polyfluoroalkyl substances)‐contaminated sites are even more complex due to the large number of ...

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 ...

In Situ Colloidal Activated Carbon for PFAS Remediation in Groundwater: Principles, Performance Expectations, and Lessons from the First Decade

Groundwater Monitoring &Remediation, Volume 46, Issue 3, Page 124-145, Summer 2026.
Abstract Injectable colloidal activated carbon (CAC) has been commercially used to remediate per and polyfluoroalkyl substances (PFAS) in groundwater since 2016. The basis of the technology is enhanced PFAS retention within the aquifer from engineered increases in aquifer‐matrix sorptivity (“PFAS enhanced retention”), with re‐equilibration from the ...

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 ...

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.
