This study assesses the quality of groundwater in the Odra River Basin in Poland, focussing on environmental health risks, temporal variability, and their association with salinity indices. A new indicator, the Groundwater Safety and Availability Index (GSAI), was developed to evaluate groundwater resources by integrating health risk and resource quantity factors, providing a novel tool for ranking water resources and informing environmental and administrative decision-making. Groundwater samples were collected between 2005 and 2021 and analysed in accordance with national standards. The results demonstrate an improvement in groundwater quality over time, indicated by a reduction in Health Index (HI) values, particularly in Lower Silesia, Lubusz, and Silesia. Significant correlations were found between HI and NO₃ (τ-Kendall = 0.40) and arsenic (τ-Kendall = 0.55). GSAI values varied across regions, with West Pomerania showing the highest groundwater safety and availability, while Silesia had the lowest. Elevated concentrations of contaminants such as arsenic and nitrates were found to significantly impact water safety, particularly during hydrogeological droughts. These findings support the need for region-specific management strategies to ensure sustainable groundwater use and mitigate health risks, with the GSAI serving as a valuable tool for policymakers and environmental planners.

Biofilm formation and its molecular signaling in bacteria resistant to ionizing radiation is not fully understood. This study aimed to investigate the genetic variations and gene expression of biofilm in an ionizing radiation-resistant Bacillus subtilis in Ramsar. Direct sequencing and quantitative PCR were applied to determine nucleotide variations and gene expression profiles of tapA-sipW-tasA, sinR, sinI, ccpA, epsA-O, spoOB, spoOA, slrA, slrR, ymcA and abrB genes.

Biotic and abiotic materials attachment to suspended particulate matter in aquatic systems can increase their toxicity and health impacts and has led to an increased need for consistent sampling across various compartments. Sedimentation traps and continuous flow centrifuges are the traditional tools for sampling suspended particulate matter, while manta trawls have been widely used for surface water sampling of suspended or floating microplastics. Limitations, however, exist in the cost of sampling and infrastructure needed to deploy such devices.

Monitoring changes in groundwater quality over time helps identify time-dependent factors influencing water safety and supports the development of effective management strategies. This study investigates the spatiotemporal evolution of groundwater chemistry in the Debrecen area, Hungary, from 2019 to 2024, using indexing, machine learning, and multivariate statistical techniques. These techniques include self-organizing maps (SOM), hierarchical cluster analysis (HCA), principal component analysis (PCA), and groundwater quality indexing (GWQI).

Pesticide residues in agricultural products and environmental water pose significant threats to human health and ecosystems. The urgent need for rapid detection and degradation of complex samples containing multiple pesticides has driven advancements in detection methods. Surface-Enhanced Raman Spectroscopy (SERS), a powerful molecular detection technique, has attracted considerable attention in food safety, environmental monitoring, and biological analysis due to its unparalleled sensitivity, non-destructive characterization capabilities, and high specificity.
