Summary: Fourier transform mid infrared (FT-MIR) spectroscopy combined with modeling techniques has been studied as a useful tool for multivariate chemical analysis in agricultural research. However, the sample preparation requirement of this method, which involves drying and fine grinding, can increase the time and cost of analysis. This study investigates the effect of different grinding times on model performance using leaf tissue samples from various crop species. The results suggest that a 5-minute fine grinding time is optimal in terms of overall model performance and sample preparation time.

Summary: In this study, a multi-compartment toxicokinetic modeling approach was used to evaluate the bioaccumulation of neonicotinoids. The study found a delayed toxicity phenomenon in aquatic invertebrates exposed to neonicotinoids. The research also demonstrated an incomplete elimination of neonicotinoids in freshwater amphipods and developed a two-compartment model to predict their uptake and elimination kinetics. The results suggest the importance of considering long-term toxic effects and irreversible receptor binding in regulatory contexts. The developed model can be used for future toxicokinetic assessments of receptor-binding contaminants.

Summary: Acidification of soils limits agricultural production globally. Traditional lime application is effective for surface acidity, but not for subsurface acidity. In this study, Mid Infrared (MIR) spectroscopy was used to monitor lime movement through soils at high resolution. Results showed limited alkalinity movement in all trial sites, with increased movement in longer-term sites. Incorporating residual lime and additional applications may be necessary to remediate subsurface acidity.

Summary: Soil bulk density (BD) is an important physical parameter for soil quality control and calculation of soil organic carbon (SOC) stock. However, laboratory analysis of BD is time-consuming and expensive, making it difficult for national-scale soil assessments. This study used chemometric and machine learning algorithms to estimate BD in Irish soil based on MIR spectral libraries. The best performance was achieved with a SVM model, which had a RPIQ of 3.61, R2 value of 0.81, and RMSEP of 0.132. The spectral soil BD model outperformed traditional pedo-transfer functions overall and showed similar accuracy for the A horizon but improved performance for other horizons.

Summary: Layered transition metal molybdates (LTMs) are proposed as slow-release fertilizer compounds for micronutrients molybdenum (Mo), zinc (Zn), and copper (Cu). LTMs were successfully prepared and characterized, and their solubility in water was tested. The LTMs showed limited stability in acidic conditions, so co-compaction with pH neutral or alkaline macronutrient carriers was explored. A Zn-based LTM co-compacted in a muriate of potash (MOP) carrier showed a slow and constant release rate of both Mo and Zn, making it a potential slow-release fertilizer or raw material for non-acidic fertilizers.

Summary: This study aimed to evaluate the performance of a soil washing plant (SWP) inremediating a PFASs-contaminated soil with high clay content. The SWP utilized physical and chemical processes to fractionate soil particles and remove PFASs. The contaminated water was treated with GAC and ion-exchange resin for reuse within the SWP. The SWP achieved high removal efficiencies (97.1% for perfluorocarboxylic acids and 94.9% for perfluorosulfonic acids) and demonstrated effective transfer of PFAS mass to the wash solution and GAC.

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.

Summary: This study aimed to estimate the contributions of diffuse and point sources of chemicals associated with plastics in wastewater. A conservative baseline was devised to classify the chemicals as point-source dominant or diffuse-source dominant when specific sampling was not possible. The results showed that bisphenol A, bisphenol S, di-isononyl phthalate, and di-methyl phthalate were dominant point-source chemicals, while phthalates were dominant diffuse-source chemicals. The estimated annual mass loads of these chemicals in wastewater treatment plants demonstrated the significant contributions from both diffuse and point sources.
