Perspectives of High‐Resolution Mass Spectrometry in Soil Science

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

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

Polymer 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 ...

Induction of oxidative stress and apoptosis by PFOS and PFOA in primary cultured hepatocytes of freshwater tilapia (Oreochromis niloticus)

, 2007
Perfluorinated organic compounds (PFOCs) are emerging persistent organic pollutants (POPs) widely present in the environment, wildlife and human. We studied the cellular toxicology of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) on ...

PFOA exposure decreases acrosome reaction and increases DNA oxidative damage by impairing the sperm head shaping in mice

Ecotoxicology and Environmental Safety
Perfluorooctanoic acid (PFOA) is a reproductive toxicant, but its effects on sperm head shaping and acrosome reaction remain unknown. Adult male Bal b/c mice were given 0, 2 or 10 mg/kg/day of PFOA for 6 weeks by gavage. Elevated sperm head malformations

Electroconductive MXene‐Thin‐Film‐Composite Membranes for Coupled Osmotic Concentration and PFAS Mineralization

Small, EarlyView.
An electroconductive MXene‐TFC membrane integrates osmotic dewatering with anodic oxidation to concentrate and mineralize PFOA at the membrane interface. The coupled AO‐PRO configuration accelerates degradation kinetics, achieves 99% rejection and up to 93% TOC removal, and lowers specific energy demand, offering a compact route for PFAS destruction ...

Network Pharmacology and In Vivo Evaluation of Lycium barbarum Polysaccharide in Preventing Perfluorooctanoic Acid-Induced Damage in Broilers

Poultry Science
To examine the guarding effects of Lycium barbarum polysaccharides (LBP) on liver and gut injury induced by perfluorooctanoic acid (PFOA) in broilers. Initially, a dose selection experiment for PFOA modeling was conducted.

PFOA Exposure Elicits Quantitative Lipidomic Changes in the Pancreas in a Mouse Model of Pancreatic Cancer

Environmental Toxicology, EarlyView.
ABSTRACT Pancreatic cancer is the fourth leading cause of cancer deaths in the US and predicted to rise to second by 2030. Several risk factors have been identified as potential contributors to pancreatic cancer development including lifestyle factors and long‐term exposure to occupational and environmental carcinogens.

The Price of Prosperity? A Historical Account of Regulating Industrial Pollution in the Netherlands

Regulation &Governance, EarlyView.
ABSTRACT Regulatory governance and state‐corporate crime studies link persistent industrial pollution to long‐term regulatory–industry interactions, yet little is known about how these interactions evolve and become entrenched. This article examines two enduring cases of industrial pollution in the Netherlands—Hoogovens/Tata Steel and DuPont de Nemours/
