Summary: Combining traditional soil sampling with real-time sampling using pXRF devices can reduce costs associated with contamination assessments. This study evaluated the potential of using both pXRF and traditional soil sampling measurements to accurately map soil contamination due to heavy metals. Integrating pXRF uncertainty with geostatistical sequential simulation and local probability distributions can accurately identify contaminated areas.

Summary: Determining elemental concentrations in plant tissue samples is crucial for analyzing their nutritional content. In this study, the reliability of portable X-ray fluorescence (pXRF) spectroscopy was compared with that of inductively coupled plasma-mass spectrometry (ICP-MS) to determine the concentrations of four micronutrients in barley shoot samples. The pXRF method showed good correlation with ICP-MS results for zinc concentration and moderate correlations for iron and copper concentrations. However, no significant correlation was found for cadmium concentration. These findings highlight the potential of pXRF as a cost-effective alternative to ICP methods for determining zinc in plant samples.

Summary: Portable X-ray fluorescence (pXRF) is a commonly used geochemical technique for multi-elemental analysis screening in contaminated sites management. Efforts have been made to study the quality of pXRF, especially for less investigated elements such as mercury (Hg) and antimony (Sb), to assist both new and experienced users. Environmental solid samples from two decommissioned mining sites in NE Italy were analyzed and compared with traditional destructive analyses. The study found that sample composition was closely related to the occurrence of false positives and overestimation at low concentrations.

Summary: To evaluate the impact of sediment contamination in hydric settings by metallic trace elements (MTE) from the controlled dump of Fez city, leachate and sediment sample analyses were conducted. The leachates had varying levels of pH, COD, NTK, and nitrate concentration, all of which exceeded discharge standards. The sediments downstream of the dump showed slightly higher pH and electrical conductivity values compared to reference samples, while the metallic element concentrations varied slightly among different sampling points.

Summary: Phytoremediation is a cost-effective and sustainable method for remediating polluted soils. However, the interactions between organic and heavy metal contaminants have not been thoroughly studied. This laboratory investigation assessed the effects of organic and heavy metal contaminants on plant growth in both separate and combined scenarios. The results showed that plants were less affected by organic contaminants, but experienced significant distress in the presence of heavy metals, with chromium being the most phytotoxic. The co-existence of chromium with other metals reduced the phytotoxicity, while lead did not exhibit significant phytotoxicity when co-existing with cadmium and chromium. Plants in mixed contaminated soil performed better than those in soil solely contaminated with heavy metals.

Summary: In this study, a grid-based soil contamination map was created using Ordinary Kriging, based on sampling data of heavy metal concentrations in soil in abandoned mine areas. Five factors affecting the prediction error of the soil contamination map were identified, and the top three factors were determined using a machine learning algorithm. The results showed that the Variogram Model, Minimum Neighbors, and Anisotropy factors had the largest impact on RMSE in the Standard interpolation. Through the combination of geostatistics and machine learning, a highly reliable soil contamination map was created at the local scale, and important factors for interpolating small amounts of soil heavy metal data were identified.

Summary: Advancements in analytical techniques have led to a better understanding of the co-occurrence of environmental contaminants. This study specifically focused on the global pattern of arsenic co-occurrence with inorganic and emerging contaminants and identified the factors driving this situation. Weathering, redox conditions, recharge/pumping, and surface leaching were found to be the major factors governing co-occurrences. Additionally, the study revealed the presence of arsenic with emerging contaminants such as pesticides, PFAS, and EDCs, which requires further exploration.

Summary: This study examined the hydrogeochemical properties of bottled waters to evaluate their quality and suggest the natural background levels of groundwater. The results showed that the bottled waters mainly consisted of the Ca-HCO3 type with low degrees of water-rock interaction. Principal component analysis revealed the dissolution and weathering processes impacting the bottled waters. The suggested natural background levels were found to be acceptable for groundwater quality management.

Summary: This study conducted a controlled CO2 release experiment in a siliciclastic aquifer in South Korea to investigate the hydrogeochemical effects of CO2 leakage on shallow groundwater. The experiment demonstrated that a limited amount of minerals dissolved and cation exchange occurred at the early stage of CO2 leakage. Additionally, Li was identified as an effective tracer for monitoring CO2 migration in siliciclastic aquifers.

Summary: This study assessed the concentrations of eleven heavy metals in groundwater and seawater from the ship-breaking industrial area of Bangladesh and found that the water quality is extremely poor. The study also revealed high levels of heavy metal pollution in both types of water samples. The pollution is primarily caused by anthropogenic factors such as ship-breaking activities and other industries in the area.

Summary: Hydrochemical and isotopic characteristics of crystalline bedrock aquifers were studied at two geological disposal research sites. The groundwater samples collected during and after drilling showed different characteristics, indicating extensive water-rock interaction in one area and recent recharge in the other. Redox conditions were also affected by drilling, with an increase in oxidization observed after drilling. The study suggests using isotopic investigations combined with hydrochemical characterization to accurately assess anoxic conditions and redox conditions in crystalline bedrock aquifers.

Summary: This study investigates the impact of tailings from gold mining on soil contamination near a river, and finds that the contamination levels are affected by the application of mercury, the discharge of light and heavy minerals, and mismanagement or spills of mercury. The distribution of soil contaminants is controlled by the specific gravity of minerals discharged to the environment, ore processing stages, and insufficient recovery and/or spills of mercury.

Summary: Water pollution is a global issue that is worsening in both developed and developing nations. Groundwater pollution has a detrimental impact on the health of billions of people and economic progress. Therefore, it is crucial to assess hydrogeochemistry, water quality, and potential health risks for effective water resource management. The study conducted analysis on groundwater samples from the Jamuna Floodplain and Madhupur tract, focusing on physicochemical parameters, hydrogeochemical characteristics, trace metals, and isotopic composition. The results reveal that the groundwater in the Floodplain area is unsuitable for drinking due to high concentrations of NO3-, As, Cr, Ni, Pb, Fe, and Mn, while the deep Holocene and Madhupur tract aquifers meet drinking water standards. The study emphasizes the importance of water management to ensure safe drinking water for future generations.

Summary: The fractionation behaviors of Cu and Zn isotopes were studied in groundwater contaminated with petroleum and treated by oxidation. The study assessed the isotopes of Cu, Zn, SSO4, and H2O2 in wells contaminated with total petroleum hydrocarbons (TPH) and treated with H2O2 in 2021 and 2022. The results suggested the occurrence of sulfate reduction and precipitation of Cu sulfides, while the Zn isotopic fingerprint of sulfide precipitation may have been masked by sorption. The use of Cu isotopes in redox reactions proved advantageous due to the wider range of Cu isotopes.

Summary: Surface water pollution caused by industrial effluent discharge is a major concern in Dhaka, Bangladesh. This study focuses on the severe river water pollution caused by effluents from a tannery village. Samples were collected from various points, and 31 parameters were observed over three seasons. The water quality indices indicate that the studied surface water is unsuitable for consumption, irrigation, and anthropogenic purposes. The presence of heavy metals poses health risks, especially for children, and requires immediate corrective action.
