A Data‐Driven Approach Coupled With Physical Constraints to Improve Groundwater Models With Structural Error

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Groundwater models are essential tools for groundwater remediation and contamination risk assessment. However, due to the simplification or inaccurate representation of real‐world groundwater systems, model structural errors are widespread and unavoidable, leading to systematic biases in model predictions.

Original scientific paper The Hall rule in fluoranthene-type benzenoid hydrocarbons

open access: yes, 2008
: The applicability of the Hall rule (linear relation between the total π-electron energy and the number of Kekulé structures) was investigated in the case of fluoranthene-type benzenoid hydrocarbons.

Protein engineering of cytochrome p450(cam) (CYP101) for the oxidation of polycyclic aromatic hydrocarbons.

open access: yes, 2000
Mutations of the active site residues F87 and Y96 greatly enhanced the activity of cytochrome P450(cam) (CYP101) from Pseudomonas putida for the oxidation of the polycyclic aromatic hydrocarbons phenanthrene, fluoranthene, pyrene and benzo[a]pyrene. Wild-

Toxic effect of polycyclic aromatic hydrocarbons (PAHs) on co-culture model of human alveolar epithelial cells (A549) and macrophages (THP-1)

open access: yesEnvironmental Sciences Europe
Polycyclic aromatic hydrocarbons (PAHs) are particulate matter bound environmental contaminants known to cause adverse effects on human health. The toxicity of carcinogenic PAH such as benzo[a]pyrene (BaP) has been extensively investigated, whereas other

Arabidopsis thaliana YUC1 reduced fluoranthene accumulation by modulating IAA content and antioxidant enzyme activities

open access: yesEcotoxicology and Environmental Safety
Indole-3-acetic acid (IAA) can regulate plant growth and thus modulate the accumulation of polycyclic aromatic hydrocarbons (PAHs). However, the effect of endogenous IAA on PAHs accumulation and its influencing factors remains unclear.
