Machine Learning-based Classification for the Prioritization of Potentially Hazardous Chemicals with Structural Alerts in Nontarget Screening

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: March 7, 2025

Nontarget screening (NTS) with liquid chromatography high-resolution mass spectrometry (LC-HRMS) is commonly used to detect unknown organic micropollutants in the environment. One of main challenges NTS prioritization relevant LC-HRMS features. A novel strategy based on structural alerts select features that correspond potentially hazardous chemicals presented here. This leverages raw tandem spectra (MS2) and machine learning models predict probability alerts. The were trained fragments neutral losses from experimental MS2 data. feasibility this approach evaluated for two groups: aromatic amines organophosphorus neural network classification model achieved an Area Under Curve Receiver Operating Characteristics (AUC-ROC) 0.97 a true positive rate 0.65 test set. random forest AUC-ROC value 0.82 0.58 successfully applied prioritize surface water samples, showcasing high potential develop implement further.

Amine Switchable Hydrophilic Solvent Vortex-Assisted Homogeneous Liquid–Liquid Microextraction and GC-MS for the Enrichment and Determination of 2, 6-DIPA Additive in Biodegradable Film

Molecules, Journal Year: 2024, Volume and Issue: 29(9), P. 2068 - 2068

Published: April 30, 2024

2, 6-diisopropylaniline (2, 6-DIPA) is a crucial non-intentionally organic additive that allows the assessment of production processes, formulation qualities, and performance variations in biodegradable mulching film. Moreover, its release into environment may have certain effects on human health. Hence, this study developed simultaneous heating hydrolysis-extraction amine switchable hydrophilic solvent vortex-assisted homogeneous liquid-liquid microextraction for gas chromatography-mass spectrometry analysis 6-DIPA corresponding isocyanates poly(butylene adipate-co-terephthalate) (PBAT) agricultural films. The conditions factors influencing efficiency microextraction, such as type volume amine, homogeneous-phase phase separation transition pH, extraction time were investigated optimized. optimum found to be H

Short-Term Exposure to 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine Induces Colonic Energy Metabolism Disorders in Rats

Journal of Agricultural and Food Chemistry, Journal Year: 2024, Volume and Issue: 72(46), P. 25931 - 25943

Published: Nov. 5, 2024

2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) is one of the most abundant heterocyclic aromatic amines generated in thermally processed meat products, and toxicities its short-term exposure intestines remain unclear. This study aimed to elucidate PhIP toxicity colons through administering orally rats for 4 weeks. The results indicated that induced colonic oxidative stress, a significant decrease serum triglyceride, disrupted gene expression pattern associated with mitochondrial electron transport chain energy metabolism. Thirteen metabolites, including lactate d-erythrose-4-phosphate, showed changes under effects. Energy metabolism pathway analysis revealed PhIP-induced disorders are characterized by inhibited glycolysis enhanced tricarboxylic acid cycle. Further investigation found altered metabolic phenotype colon epithelial cells increase aerobic respiration. In summary, our provides new insights into exposure.
