Summary: This study compares the solubility of nine forms of copper in soils and finds that the complexation of copper with soil phases is the main process determining solubility, while dissolution limits the increase of soluble copper in the form of nanoparticle. Soil pH and organic carbon content affect the dissolution kinetics and equilibrium concentration of copper. The proportion of readily available copper is very low in the short term. Soil moisture content has a significant impact on the measured soluble copper.

Summary: This study investigated the effect of organic carbon (OC) and salinity on the desorption of perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonic acid (PFHxS) from estuarine sediments. The results showed that the desorption of PFAS from the sediments was consistent with their sorption behavior, with PFOS exhibiting lower desorption. Sediments with high OC content and high salinity had the lowest desorption percentages of PFAS. The influence of salinity on desorption was less than that of OC content.

Summary: This study investigated the effect of soluble cations on the sorption of anionic PFAS in soils and found that increasing cation concentrations enhanced the sorption of PFAS. Long-chain PFAS were completely removed from solution at higher cation concentrations. The primary effect of cations was through screening of negative charges on PFAS head groups and reorientation of molecules at the interface between organic matter surfaces and soil solution, resulting in greater hydrophobic interactions between PFAS and soil surfaces.

Summary: The historical use of AFFF containing PFAS for fire-fighting activities has led to widespread infrastructure contamination, posing ongoing environmental risks. This study measured PFAS concentrations in a concrete fire training pad with historical AFFF use, revealing spatial variability throughout the pad. Surface chips and whole cores of concrete, including the underlying aggregate base, were collected for analysis. Despite variations in individual PFAS along the core depth profile, higher surface concentrations generally followed the water movement direction. The study highlights the presence of PFAS throughout the concrete, with variable concentrations across the profile.
