Evaluation of synergistic factors on BTEX urinary biomarkers in motorcycle riders exposed to heavy traffic in a megacity

open access: yesScientific Reports
Fuel combustion is a major source of volatile organic compounds such as benzene, a known human carcinogen. Benzene is metabolized into intermediate biomarkers that can be used to assess the extent of exposure.

New branches in the degradation pathway of monochlorocatechols by Aspergillus nidulans: a metabolomics analysis [PDF]

open access: yes, 2016
A collective view of the degradation of monochlorocatechols in fungi is yet to be attained, though these compounds are recognised as key degradation intermediates of numerous chlorinated aromatic hydrocarbons, including monochlorophenols.

Ozonolysis of Lignin: From Extensive Degradation to Selective Ring‐Opening Oxidation

open access: yesChemSusChem, Volume 19, Issue 4, 25 February 2026.
Despite its potential as a renewable feedstock, lignin, a major component of plant cell walls and a by‐product of the pulp and paper industry, has long been underutilized. Historically, pulp mills employed ozonolysis, a powerful oxidative process, to delignify cellulosic fibers and break down lignin.

Enhanced Protocatechuic Acid Production From Glucose Using Pseudomonas putida 3-Dehydroshikimate Dehydratase Expressed in a Phenylalanine-Overproducing Mutant of Escherichia coli

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Protocatechuic acid (PCA) is a strong antioxidant and is also a potential platform for polymer building blocks like vanillic acid, vanillin, muconic acid, and adipic acid.

Bridging Green Chemistry and Circular Economy: A Pathway to Sustainable Polyester Plastics Through Feedstock, Synthesis, and Waste Upcycling

open access: yesAdvanced Science, Volume 13, Issue 11, 23 February 2026.
This review summarizes green and low‐carbon strategies throughout the entire life cycle of polyester plastics, including sustainable monomer synthesis, optimization polymerization, efficient recycling, and advanced upcycling technologies. The synergistic implementation of these strategies is expected to significantly promote the development of a ...

Pollutant effects on genotoxic parameters and tumor-associated protein levels in adults: a cross sectional study

open access: yesEnvironmental Health, 2008
Background This study intended to investigate whether residence in areas polluted by heavy industry, waste incineration, a high density of traffic and housing or intensive use of pesticides, could contribute to the high incidence of cancer observed in ...

Exposure and risk assessment of urinary trans, trans-Muconic acid in school-age children in the vicinity of a petrochemical complex in Central Taiwan

open access: yesFrontiers in Public Health, 2023
School-age children living near large petrochemical factories may be at high risk of exposure to benzene released during manufacturing processes. We aimed to investigate the urinary concentrations of trans, trans-muconic acid (t,t-MA) in school-age ...

Evaluation of exposure biomarkers in offshore workers exposed to low benzene and toluene concentrations [PDF]

open access: yes, 2018
Purpose: Characterize ethylbenzene and xylene air concentrations, and explore the biological exposure markers (urinary t,t-muconic acid (t,t-MA) and unmetabolized toluene) among petroleum workers offshore. Offshore workers have increased health risks due

Investigation Into the Role of Reductants and Cosubstrates in Lytic Polysaccharide Monooxygenase Thermothielavioides terrestris AA9E Binding to Cellulose by Single‐Molecule Imaging

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 1, Page 52-63, January 2026.
In glucose oxidase + catalase (GODCAT) and protocatechuic acid/protocatechuate 3,4‐dioxygenase (PCA/PCD) oxygen‐scavenging buffers, some Cy5‐TtAA9E bound to crystalline cellulose fibrils. Adding ascorbic acid (AscA) vastly increased enzyme binding to cellulose in the GODCAT buffer but diminished enzyme binding to cellulose in the PCA/PCD buffer ...
