Summary: The study evaluated the use of acesulfame and chloride as co-tracers to represent the impact of pollution originating from wastewater and road de-icing on water quality in a municipal drinking water source. Spatial and temporal analyses of these tracers allowed for pinpointing probable origins of contamination and delineating priority intervention zones for improving drinking water source protection by municipal authorities.

Summary: In this study, chronic toxicity tests were conducted to investigate the effects of iron (Fe) on three aquatic species in laboratory freshwaters. It was found that the concentrations of Fe required to elicit a biological response often exceeded the solubility limits of Fe(III) under conditions relevant to natural surface waters. The toxicity of Fe to the tested species was influenced by various water quality parameters, such as pH, hardness, and dissolved organic carbon.

Summary: Rising salinity from road deicing salts poses a threat to the survival and reproduction of freshwater organisms. Two experiments were conducted to examine the impact of road salt concentration and water hardness on Daphnia pulex. The results showed that D. pulex survival was significantly reduced at higher salt concentrations and in hard water. The number of offspring produced per individual also declined with increasing chloride concentration and water hardness.

Summary: This article investigates the impact of the largest roads in Poland on groundwater quality and evaluates the extent of their influence. The study finds that the groundwater quality near roads may be negatively affected, as indicated by the increased concentrations of chloride and sodium ions. The findings are important for a deeper understanding of the environmental impact of road transportation.

Summary: Laboratory studies show temporary salt storage in soils, but field studies are rare, and the mechanisms of salt transport across hydrological reservoirs remain unknown. The research observed dual retention mechanisms of Na+ and Cl- in soils, along with ion exchange processes causing slow movement and retention of ions in porewater.

Summary: This study investigated the factors affecting the toxicity of nickel to aquatic organisms using multiple linear regression models and the biotic ligand model. Hardness and dissolved organic carbon were commonly selected as explanatory variables. The performances of the two models were largely equal, with differences becoming more apparent when looking at subsets of the data.

Summary: Long-term road salt application has led to increased chloride concentrations in public drinking water wells. Best Management Practices (BMPs) have been implemented to mitigate the impact of road deicing compounds on groundwater quality. The study shows that controlled reductions in road salt applications can gradually reduce chloride levels in groundwater, but the response of municipal supply wells is slow.

Summary: This review examines nickel toxicity to aquatic organisms, finding that dissolved organic carbon and hardness can reduce nickel toxicity to fish and aquatic invertebrates, and pH has inconsistent effects on toxicity, with a unique effect on C. dubia. The study suggests that a single set of parameters in the nickel BLM can effectively predict toxicity for all aquatic organisms in both acute and chronic exposures.

Summary: This study demonstrates the value of DC-IP imaging, in both 3D and high-resolution, for characterizing streambed architecture and interpreting groundwater-surface water exchange patterns. It shows that DC-IP imaging can provide rapid, non-invasive, and continuous information on streambed lithology and its control on GW-SW exchanges, which has been underutilized in previous investigations.

Summary: Streambed sediment and groundwater are important sources of soluble reactive phosphorus (SRP) in freshwater catchments. This study evaluates the variability and controls on porewater SRP in an agricultural streambed, finding high SRP concentrations in low groundwater discharge zones and a link to iron and manganese redox cycling. Temporal variability in porewater SRP was observed, but no distinct seasonal changes were observed along the stream reach.

Summary: This study assessed the association between groundwater and stream biofilm communities and processes in a headwater stream network in southern Ontario, Canada. The results showed that seasonal variation played a significant role in driving diatom assemblage composition and cellulose decomposition. However, there was no association between groundwater input and stream biofilm condition, suggesting surface water influences may have overwhelmed the groundwater signal at the reach scale.

Summary: This study assessed the stream biofilm communities and cellulose decomposition in run and riffle habitats across three stream reaches with different groundwater inputs in Kintore Creek, Canada. The results showed that algal biomass and diatom assemblage composition differed between runs and riffles in reaches with moderate and high groundwater inputs, but not in the low groundwater reach. Additionally, streambed cellulose decomposition was faster in riffles than in runs in reaches with moderate and high groundwater input.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
