Chemistry of Combustion-generated Nanoparticles and their Transformation in Particle Filters

CHIMIA
Combustion-generated nanoparticles with diameters of 10-200 nm are ideal shuttles to transport compounds into the human body. The so-called Trojan Horse effect describes the translocation of persistent nanoparticles covered with adsorbates across the ...

Novel 2-amino-isoflavones exhibit aryl hydrocarbon receptor agonist or antagonist activity in a species/cell-specific context [PDF]

, 2012
The aryl hydrocarbon receptor (AhR) mediates the induction of a variety of xenobiotic metabolism genes. Activation of the AhR occurs through binding to a group of structurally diverse compounds, most notably dioxins, which are exogenous ligands ...

Biochar Production From Plastic‐Contaminated Biomass

GCB Bioenergy, Volume 16, Issue 11, November 2024.
Anaerobic digestion and composting of biowastes recycle carbon and nutrients for agriculture, but plastic contamination introduces microplastics into ecosystems. Pyrolysis can eliminate plastics and creates carbon sinks with biochar. This study produced biochar from wood residues with 10% plastic at 450°C and 600°C, compared to controls of beech wood ...

Scientific opinion on the exposure of the adult population of the Republic of Croatia to dioxins and dioxin‐like polychlorinated biphenyls from different types of food.

Food Risk Assess Europe, Volume 2, Issue 4, October 2024.
Summary Dioxins (PCDD/F) and dioxin‐like polychlorinated biphenyls (DL‐PCB) are harmful compounds that remain in the environment and accumulate in the food chain. Polychlorinated dibenzo‐p‐dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are mainly by‐products of industrial processes, but can also be the result of natural processes such as ...

Safety and efficacy of a feed additive consisting of lutein‐rich extract of Tagetes erecta L. for turkeys for fattening (EW Nutrition)

EFSA Journal, Volume 22, Issue 10, October 2024.
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of lutein‐rich extract of Tagetes erecta L. as sensory additive (functional group: Colourants (ii) substances which, when fed to animals, add colours to food of animal origin) for turkeys for fattening.

Burning question: Rethinking organohalide degradation strategy for bioremediation applications

Microbial Biotechnology, Volume 17, Issue 8, August 2024.
This review specifically focuses on the novel solution of organohalide bioremediation, proposing redox‐potential‐mediated hybrid bioprocesses tailored to the complexities of organohalide pollution. Abstract Organohalides are widespread pollutants that pose significant environmental hazards due to their high degree of halogenation and elevated redox ...
