The impact of process variables on the removal of PBDEs and NPEOs during simulated activated sludge treatment [PDF]
Sewage effluent is known to be a major source of endocrine disrupting compounds entering the aquatic environment. More efficient wastewater treatment could reduce the environmental load but, in order to achieve this factors determining compound behaviour

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

This study adapted and validated the dynamiCROP model for spinach, a leafy vegetable not previously included in its standard framework. The findings confirm that model‐predicted pesticide concentrations, when integrated into hazard quotient (HQ) calculations, can effectively support dietary risk assessment.

A simple method for determination of deoxynivalenol in cereals and flours
An effective and fast method for determination of deoxynivalenol (DON) in cereals and flours has been developed. The immunoaffinity column was used for the isolation of DON from wheat, corn, rice and flour extract.

A scalable fabrication method based on chemically tuned controlled dielectric breakdown (CT‐CDB) enables heterogeneous multilayer nanopores integrating SiNx with 2D materials such as hBN, MoS2, and graphene. The resulting nanopores exhibit distinct electrokinetic behaviors and low noise, allowing structure‐dependent single‐protein sensing.

Determination of Nitroaromatic, Nitramine, and Nitrate Ester Explosives in Soils Using GC-ECD [PDF]
Abstract : Nitroaromatic, nitramine, and nitrate ester explosives are analytes of interest for hazardous waste site characterization and land mine detection. Traditionally determined by high-performance liquid chromatography (HPLC), these thermally labile analytes may be determined by gas chromatography (GC) by using direct injection into a deactivated

First atmospheric observations of three chlorofluorocarbons [PDF]
We report the first atmospheric observations of the Chlorofluorocarbons (CFCs) trifluorochloroethene, 3-chloropentafluoropropene and 4,4-dichlorohexafluoro-1-butene by means of Gas Chromatography with Electron Capture and Mass Spectrometric detection (GC-
