Sustainability in Analytical Chemistry Illustrated by Pharmaceutical Nitrosamine Testing

ELECTROPHORESIS, EarlyView.
ABSTRACT Following the valsartan scandal in 2018, the testing of drug substances and drug products for N‐nitrosamines has become a critical and mandatory quality control measure. The European Pharmacopoeia chapter 2.5.42 currently describes three analytical methods for this purpose: HPLC–MS/MS, GC–MS, and GC–MS/MS.

Enantioselective Determination of Amphetamine‐Type Stimulants in Environmental Waters Using SPE and CE–MS/MS

ELECTROPHORESIS, EarlyView.
ABSTRACT The growing concern over drug abuse, particularly involving amphetamine‐type substances (ATS), has led to their monitoring in environmental waters. These chiral compounds, commonly found in river water and wastewater treatment plant (WWTP) effluents, require analytical methods capable of enantiomeric discrimination, as their enantiomers can ...

Epigenotoxicity: Decoding the epigenetic imprints of genotoxic agents and their implications for regulatory genetic toxicology

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.

Physicochemical Properties and Antioxidant Activity of Apocynum Honey in Different Regions of Xinjiang

Food Chemistry International, EarlyView.
ABSTRACT In this study, honey produced from Apocynum venetum L. was collected from BC (Bachu County), SY (Shaya County), and YL (Yuli County) in Xinjiang. The basic physical and chemical properties of the honey, and the contents of total phenols, total flavonoids, and amino acids were analyzed, and 16 types of polyphenols were quantified using triple ...

Comparative Analysis of Fungal Communities and the Key “Golden‐Flower” Fungi in Fu Brick Tea From Seven Chinese Regions and Their Effects on the Quality of Summer‐Autumn Tea

Food Frontiers, EarlyView.
This study systematically investigated 52 Fu brick tea (FBT) samples collected from seven representative regions in China. High‐through put sequencing revealed that Aspergillus, Wallemia, and Candida were the predominant fungal genera across the samples.
