Networks of rivers and their tributaries serve as dynamic habitats for these potentially harmful metals through aqueous–sedimentary equilibrium shifts. Hence, determining the distinct chemical forms of a given heavy metal in sediment is crucial for evaluating its bio-lability and toxicity. This study demonstrates the geochemical speciation using a sequential extraction procedure to fractionate individual phases (exchangeable, carbonate, Fe–Mn oxide, organic, and residual) of nine heavy metals (Cu, Pb, Cd, Zn, Fe, Co, Ni, Mn, and Cr) in the sediment of a river system in Hai Duong, a deltaic province in Vietnam. A quantitative assessment of environmental risk factors (<em>e.g.</em>, contamination factor and risk assessment code) and the pseudo-partitioning coefficient between pore water and sediment was conducted to define the pollution levels of heavy metals and their contaminated areas. Furthermore, multivariate analyses facilitate a profound comprehension of the contributions to pollution. Analyses of the extracts from the sequential extraction procedure were performed by inductively coupled plasma-mass spectrometry. The results of sedimentary heavy metal speciation indicate that the critical risks of Cd (15.8–38.4%) and Mn (16.3–53.8%) to the aquatic ecosystem are due to their higher retrieval from the exchangeable fraction. Additionally, an appreciable percentage of Co (26.3–58.0%), Mn (16.8–66.3%), Ni (16.0–53.1%), Pb (6.75–69.7%), and Zn (4.42–45.8%) in the carbonate fraction highlights a strong tendency for co-precipitation or ion exchange of these metals with carbonate minerals. Whilst colloids of Fe–Mn oxides act as efficient scavengers for metals such as Fe, Mn, Zn, and Pb, organic matter forms primarily function in trapping Cu, Pb, Fe, Cr, Co, and Ni. Our findings in the ecological risk evaluations and multivariate analyses indicate that Cr, Ni, and Fe are ascribed to natural lithogenic provenances. In contrast, anthropogenic inputs induce Cd, Mn, Cu, and Pb high-environmental risks.</p>","PeriodicalId":72941,"journal":{"name":"Environmental science.

Inhibition of enzymes related to energy metabolism is hypothesized as one of the mechanisms associated with the physiological impacts of ocean acidification. Therefore, a mesocosm experiment was conducted to investigate whether three levels of decreasing seawater pH could alter the activity of key enzymes involved in the energy metabolism in <em>M. alcicornis</em>. Hydrocorals were acclimated to marine mesocosm conditions for 20 days and then exposed to different seawater pH levels [ambient pH (8.1) and experimental pH (7.8, 7.5 and 7.2)] for 16 and 30 days. Endpoints analyzed included the activity of key enzymes involved in the regulation of the glycolytic pathway (hexokinase and pyruvate kinase), aerobic energy production <em>via</em> the Krebs cycle (citrate synthase) and anaerobic energy production <em>via</em> lactate formation (lactate dehydrogenase). The results obtained show that only citrate synthase was affected by seawater acidification, as a marked reduction in its activity was observed at all experimental pH levels tested (7.8, 7.5 and 7.2). This finding indicates that reduced growth previously reported for <em>M. alcicornis</em> under seawater acidification conditions can be explained, at least in part, by a negative impact on the Krebs cycle, a major pathway involved in aerobic energy production.</p>","PeriodicalId":72941,"journal":{"name":"Environmental science.

Human eDNA sequences were prominent in all water and sand samples such that they had less value for discriminating between sewage occurrence at sites. Mallard duck, muskrat, beaver, raccoon, gull, robin, chicken, red fox, and cow eDNA sequences were common across all locations.

Chicken, cow, and dog eDNA sequences and the human bacterial MST DNA marker often showed a higher frequency of occurrence on Beach Action Value (BAV) exceedance days. The surprisingly widespread detection of chicken and cow eDNA sequences was likely from incompletely digested human food, raising caution for interpreting eDNA results related to food animals in sewage-contaminated urban settings.

While commercial monitoring systems effectively serve water utilities and regulatory agencies, many communities lack the resources for regular water quality assessment. We present approaches for developing low-cost monitoring systems specifically designed for community-based environmental monitoring programs, citizen science initiatives, and educational applications. Through systematic analysis of 84 peer-reviewed papers on low-cost water quality monitoring, we identify key implementation approaches, common challenges, and successful design strategies. This analysis informs our tutorial recommendations and provides evidence-based guidance for system development. Specifically, we introduce a web-based portal AQWIC – Aquatic Quality Watch Informed by Communities. This open-source portal includes (1) tutorials on how to construct, program, and deploy water quality sensor systems using commercially available, low-cost components; and (2) an interactive water quality database where users can input their collected water quality data with geolocation. We highlight the functionality of AQWIC and review a set of commercially available low-cost water sensors through several deployments both in the United States and Colombia. The sensor module used is capable of measuring conductivity, temperature, pH, and turbidity, providing a cost-effective alternative to traditional testing methods. Our findings demonstrate that the conductivity, temperature, and pH sensors offer reliable and consistent results, aligning with conventional testing methods over several week periods. However, we also observed limitations in the accuracy of the turbidity sensor, emphasizing the need for improved precision at lower turbidity levels. By offering a cost-effective and user-friendly approach to real-time water quality monitoring, this work aims to empower communities to monitor and characterize their water quality and makes significant strides toward ensuring equitable access to safe water for all.</p>","PeriodicalId":72941,"journal":{"name":"Environmental science.

Increased human activity in the Arctic as the climate warms may enhance the significance of local sources. Furthermore, climate change may lead to secondary sources of POPs and CEACs from existing reservoirs in the Arctic. This review examines the emerging evidence for releases from these secondary sources of formerly deposited POPs and CEACs as the Arctic climate warms and the potential for future releases with increased infrastructure development and economic activity. Arctic permafrost degradation represents an important source of natural and anthropogenic polycyclic aromatic hydrocarbons (PAHs), and indications exist of releases of POPs related to permafrost thaw, from previous deposition as well as waste sites. Deposition of POPs and some CEACs to Arctic glaciers is relatively well studied while fewer studies explore the impacts of remobilization. Expansion of economic development has the potential for increasing emissions or creating new sources of CEACs in the Arctic. The predicted northward expansion of agriculture, aquaculture, and ship traffic could bring increased emissions of CEACs to northern waters, including pesticides not previously used in the Arctic. Increased industrial chemical use, <em>e.g.</em> fire-fighting foams, flame retardants, lubricant and plastic additives, is likely to occur following the expansion of infrastructure such as airports, seaports, mining, and oil and gas development. While PAHs are relatively well-studied, there is an urgent need for environmental measurements and modelling of emissions of CEACs associated with the expansion of economic activity in the Arctic as well as to predict the future release of legacy POPs from secondary sources, particularly from permafrost.</p>","PeriodicalId":72941,"journal":{"name":"Environmental science.
