Unearthing the shadows of history: Chemical traces of Second World War atrocities in the Szpęgawski Forest and Death Valley, Poland

Archaeometry, Volume 67, Issue 2, Page 424-438, April 2025.
Abstract This article presents the results of analyses of the chemical composition of organic matter and the occurrence of characteristic geochemical and biochemical markers in 17 samples collected from the Second World War mass graves excavated in the Szpęgawski Forest and Death Valley, Poland. The results show that attempts to cover up mass crimes by

Enhanced biodegradation of PAHs in historically contaminated soil by M. gilvum inoculated biochar [PDF]

, 2017
The inoculation of rice straw biochar with PAH-degrading Mycobacterium gilvum (1.27 × 1011 ± 1.24 × 1010 cell g−1), and the subsequent amendment of this composite material to PAHs contaminated (677 mg kg−1) coke plant soil, was conducted in order to ...

A Stable Carbon‐Centered Radical Showing Six Amphoteric Redox States

Chemistry – A European Journal, Volume 31, Issue 6, January 27, 2025.
A fully conjugated system built by alternate fusion of four benzene and three cyclopentadiene rings is a further rare example of an air‐ and moisture‐stable carbon‐centered hydrocarbon radical. It was synthesized by double ortho fusion and was extensively characterized by spectroscopic and computational methods.

Impact of carwash discharge on stormwater quality (Toulouse, France) [PDF]

, 2010
The contribution of discharge from carwashes to pollutant levels in stormwater was evaluated. Five carwashes and two outlets in the city of Toulouse (France) were selected. Water samples were collected from December 2006 to December 2007.

Development of Continuous‐Flow Reactions for the Synthesis of Anti‐Alzheimer Drug Memantine

Chemistry – A European Journal, Volume 31, Issue 5, January 22, 2025.
Memantine hydrochloride, an NMDA receptor antagonist used in Alzheimer's treatment, features an adamantane core with a bridgehead amino group. Its synthesis from acenaphthene involves hydrogenation, skeletal rearrangement, nitration, and reduction. Continuous‐flow reactions were explored for each step to develop a continuous manufacturing process for ...

Gas-Phase Synthesis of Triphenylene (C18 H12 ). [PDF]

, 2019
For the last decades, the hydrogen-abstraction-acetylene-addition (HACA) mechanism has been widely invoked to rationalize the high-temperature synthesis of PAHs as detected in carbonaceous meteorites (CM) and proposed to exist in the interstellar medium (

Tracing PAHs in Indoor Dusts as Thirdhand Smoke: The Association With Sick Building Syndrome (SBS) and Probabilistic Human Risk Assessment

Indoor Air, Volume 2025, Issue 1, 2025.
Tobacco smoke is a significant contributor to indoor air pollution and poses serious health risks. This study surveyed the levels of polycyclic aromatic hydrocarbons (PAHs) in smoker household dust and the association between PAHs in dust and symptoms of sick building syndrome (SBS).
