Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Temperature-dependent bioaccumulation of polycyclic aromatic hydrocarbons.

open access: yes, 2009
Bioaccumulation factors (BAFs) play a key role in risk assessment of chemicals in sediments and soils. For hydrophobic organic chemicals (HOCs), BAFs are, however, difficult to determine and values are mostly obtained by modeling.

High‐strength composites by thiocracking of high‐polypropylene‐content mixed waste

open access: yesPolymer International, EarlyView.
Mixed plastic waste made up of polystyrene and polypropylene was reacted with elemental sulfur to give high‐strength composites. Abstract Mixed‐material municipal waste poses a persistent end‐of‐life management challenge because the heterogeneous composition limits efficient separation and recycling. After disposal, mixed‐material waste often fragments

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

open access: yesMarine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

Combined Effects of Arsenic and Cadmium With Selenium on Oxidative Stress Indicators in Goldfish: Implications for Veterinary Toxicology. [PDF]

open access: yesVet Med Sci
Co‐exposure to arsenic and cadmium alters metal accumulation and oxidative stress in goldfish. Selenium reduces arsenic bioaccumulation and lipid peroxidation while enhancing antioxidant defences. Findings highlight metal‐specific interactions, with selenium offering partial protection, emphasizing ecological risks and the importance of monitoring ...

Agricultural and environmental drivers of variation in the composition of food crops: A scoping review

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Agricultural management and environmental conditions influence the biochemical composition of food crops; however, the specific drivers of this variation remain insufficiently understood, despite their importance for climate change adaptation and human health.

Illegal Gold Mining in the Brazilian Amazon: Environmental Degradation in Yanomami Indigenous Lands, and Regulatory Failures

open access: yesSustainable Development, EarlyView.
ABSTRACT Illegal gold mining has emerged as a major sustainability threat in the Amazon, eroding Indigenous rights, forest integrity, and climate mitigation efforts. This study examines how international market incentives relate to the expansion of illegal mining and associated deforestation within the Yanomami Indigenous Territory (YIT) from 2008 to ...

Fluorinated Hypercrosslinked Polymers with Exceptional Capacity for Perfluorooctanoic Acid Removal from Water

open access: yesSmall, EarlyView.
Fluorinated hypercrosslinked polymers (FHCPs) are reported as highly efficient sorbents for the rapid removal of perfluorooctanoic acid (PFOA) from water. The materials integrate strong fluorophilic interactions, extensive porosity, and excellent chemical stability, delivering fast adsorption kinetics, high uptake capacity, and selective PFOA removal ...

Rational Design and Development of Organic Afterglow Nanoparticles for Image‐Guided Interventions

open access: yesSmall Methods, EarlyView.
This review outlines the rational design, synthesis, and standardized characterization of organic afterglow nanoparticles for biomedical imaging and therapy. Mechanistic insights into chemically initiated electron exchange luminescence and reactive oxygen species‐mediated processes are connected to molecular engineering and nanoparticle fabrication ...

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...
