Exploring the Cumulative Selectivity of Polycyclic Aromatic Hydrocarbons in Phytoplankton, Water, and Sediment in Typical Urban Water Bodies

open access: yesWater, 2022
To understand the interactions among eutrophication, algal bloom, and POPs (persistent organic pollutants) in freshwater ecosystems, the cumulative selectivity of PAHs (polycyclic aromatic hydrocarbons) in phytoplankton, water, and sediment with ...

The polycyclic aromatic hydrocarbon concentrations in soils in the Region of Valasske Mezirici, the Czech Republic [PDF]

open access: yes, 2009
The polycyclic aromatic hydrocarbon (PAH) contamination of urban, agricultural and forest soil samples was investigated from samples obtained in the surroundings of Valasske Mezirici. Valasske Mezirici is a town located in the north-east mountainous part

Modelling and simulation of hydrogen production via natural gas plasma pyrolysis

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 3, Page 1174-1189, March 2026.
Methane pyrolysis simulation model. Abstract Plasma pyrolysis is a cutting‐edge technology that produces hydrogen and solid carbon from methane without emitting carbon dioxide. In this study, we developed a process simulation model in Aspen HYSYS to analyze the behaviour of this technology at the commercial scale.

Time since discharge of 9mm cartridges by headspace analysis, part 2: Ageing study and estimation of the time since discharge using multivariate regression. [PDF]

open access: yes, 2017
Estimating the time since discharge of spent cartridges can be a valuable tool in the forensic investigation of firearm-related crimes. To reach this aim, it was previously proposed that the decrease of volatile organic compounds released during ...

Shortcut to Highly Fluorescent Perylene Derivatives: From Fluoranthene Fissure‐Coupling to Late‐Stage Aromatic Extension

open access: yesChemistryEurope, Volume 3, Issue 6, November 11, 2025.
A two‐step shortcut for access to highly soluble, bent, and extended perylene‐based nanographene P1 from a nonperylene aromatic homologation precursor is presented. The modular, stepwise, and rational π‐extension postfunctionalization strategy allows for the tuning of the fluorescent emission properties to reach high quantum yields up to 0.78, giving ...

Fast solid-phase extraction-gas chromatography-mass spectrometry procedure for oil fingerprinting. Application to the Prestige oil spill. [PDF]

open access: yes, 2004
A rapid and simple fractionation procedure using solid-phase extraction (SPE) cartridges was developed for an accurate determination of aliphatic and polycyclic aromatic hydrocarbons in petroleum residues and further application in chemical ...

Waste tyres pyrolysis oil (WTPO) as an alternative source of fuel and chemicals: a review

open access: yesZaštita Materijala
Waste tyres are dumped and common kind of abandon solid waste. Almost 3 billion tyres are produced each year and each tyre produced will eventually join the waste products and if not properly handled will become pollutant.

Sedimentary records of polycyclic aromatic hydrocarbons (PAHs) in remote lakes across the Tibetan Plateau [PDF]

open access: yes, 2016
Sediment cores from five lakes across the Tibetan Plateau were used as natural archives to study the time trends of polycyclic aromatic hydrocarbons (PAHs). The depositional flux of PAHs generally showed an increasing trend from the deeper layers towards

Micropollutants and Their Interactions With Relevant Environmental Viruses

open access: yesEnvironmental Microbiology, Volume 27, Issue 10, October 2025.
Environmental micropollutants increase virus stability. ABSTRACT Emerging pollutants encompass a diverse array of chemicals classified as micropollutants, including pharmaceuticals and microplastics (MPs). Viruses are known to adsorb onto MPs, including binding to bacterial biofilms that form the plastisphere.
