This study investigates the release of PFASs from aqueous film-forming foam (AFFF)-impacted soils under constant and variably saturated conditions. PFASs, used in fire suppression foam, contaminate soils and pose long-term groundwater risks. Previous research shows that air-water interfaces in unsaturated soils complicate PFAS release. The study used field-collected vadose zone soils in column experiments with artificial rainwater, flushing under both constant and variably saturated conditions. Effluents were analyzed for a range of PFASs to evaluate how unsaturated conditions affect PFAS flux to groundwater. The findings aim to improve understanding of PFAS release dynamics in the unsaturated zone.

The article examines the potential of soil microbial communities and advanced omics technologies to tackle environmental contamination caused by emerging organic contaminants (EOCs). These contaminants, which include pharmaceuticals, pesticides, microplastics, and industrial chemicals, present significant risks to ecosystems and human health.

Microplastics enter the environment through plastic-containing products. The Dutch authorities aim to identify the main sources of these emissions in the Netherlands as to develop measures to reduce microplastic emissions.

The authors explore the environmental and health impact of persistent chemicals, specifically per- and polyfluoroalkyl substances (PFAS), and compare it to Rachel Carson's 1962 book Silent Spring, which exposed the dangers of DDT and leading to stricter regulations and environmental awareness.

This study emphasizes the alarming environmental and health implications of trifluoroacetic acid (TFA), a type of perfluoroalkyl acid (PFAA), which is by far the most abundant PFAS compound in the environment. TFA, which was initially associated with the degradation of fluorinated refrigerants introduced as alternatives for ozone-depleting CFCs, has become increasingly alarming due to its widespread presence in drinking water and human blood.

The HBM4EU (Human Biomonitoring for Europe) project focuses on PFAS (perfluoroalkyl and polyfluoroalky substances) exposure levels among European teenagers and investigates the factors influencing these levels. PFAS are synthetic chemicals found in consumer products, and their persistence in the environment makes them bioaccumulate in humans and wildlife.

The study provides a comprehensive analysis of the potential and current advancements in mycoremediation, the bioremediation technology using fungi to degrade environmental pollutants.

Microplastics and potentially toxic elements (PTEs) in agricultural systems are subject to a growing concern with regards to food safety. Microplastics, which have more and more become recognized as soil pollutants, can adsorb PTEs, such as heavy metals, increasing their mobility and potential absorption by plants.

There is concern of the growing presence of unregulated anthropogenic substances, such as pharmaceuticals and PFAS, in European groundwater. The EU Groundwater Watch List (GWWL) was established, a voluntary initiative designed to identify and monitor substances that pose risks to groundwater quality.

In this study the aim was to establish anthropogenic background values of PFAS in soil and groundwater in Flanders, focusing on areas free from known PFAS sources. Spatial data on known or potential PFAS sources like no-regret zones (i.e. areas with known PFAS impacts), firefighting training grounds, landfills,…  was collected and merged into 1 map to select unsuspected areas.
