Chemicals in the aquatic environment can be harmful to organisms and ecosystems. Knowledge on effect concentrations as well mechanisms modes of interaction with biological molecules signaling pathways is necessary perform chemical risk assessment identify toxic compounds. To this end, we developed criteria a pipeline for harvesting summarizing from US ECOTOX database three species groups algae, crustaceans, fish researched action more than 3,300 environmentally relevant chemicals literature databases. We provide curated dataset ready used based monitoring data first comprehensive collection categorization environmental chemicals. Authorities, regulators, scientists use grouping chemicals, establishment meaningful groups, development vitro silico approaches testing assessment.

The high-mountain lakes of the Alps, perched like glistening gems in cradle Europe's most formidable mountain range, have for generations epitomized nature's majesty. These remote and pristine bodies water served as invaluable sentinels global change, repositories geological history, sources freshwater surrounding regions. Yet, despite their seemingly imperturbable beauty seclusion, these are not immune to evolving forces our changing world. Re-emerging threats, exacerbated by relentless march climate change intensified human activities, cast a shadow over future, posing profound challenges that demand attention. aim this perspective is shed light on main emerging raise awareness, advocate proactive actions aimed at preserving protecting lakes. threats include retreat glaciers, UV radiation, long-range transport contaminants, impact alien species usage Alpine storage power stations. Additionally, increased tourism recreational activities environments can cause habitat disturbance, further endangering unique ecosystems. present article also offers valuable perspectives necessity monitoring research efforts Such crucial comprehending ecological well-being ecosystems, evaluating consequences environmental shifts, devising successful conservation strategies.

The release of chemicals into the environment presents a significant threat to aquatic ecosystems dependent on proximity emission sources and seasonal dynamics mobilization. While spatial-temporal information water pollution in Europe is increasing, there are substantial knowledge gaps tropical countries. Thus, we took Lake Victoria South Basin western Kenya as case study identify spatial hot spots contamination, quantified toxic risks different groups organisms, identified risk drivers. For this purpose, analyzed grab samples from five rivers with agricultural wastewater treatment plants their catchment four seasons. We used liquid chromatography coupled high resolution mass spectrometry (LC-HRMS) target list 785 organic micropollutants. A total 307 compounds were detected concentrations ranging 0.3 ng/L 6.6 μg/L. Using Toxic Unit (TU) approach based mixture toxicity standard test crustaceans most affected group followed by algae fish. crustaceans, chronic thresholds exceeded 96 % all samples, while 56 expected be acutely toxic, highest February during dry season. High unit values for fish recorded July season May wet Diazinon, imidacloprid, clothianidin pirimiphos-methyl major drivers crustacean triclosan herbicide mixtures drive seasons, respectively. 18 found exceed acute environmental thresholds. With study, strong patterns pollution, could confirmed informing prioritization monitoring abatement enhance quality reduce risks.

Abstract The good functioning of aquatic ecosystems is essential for providing diverse ecosystem services that benefit humans. degradation health due to continuous stressors, such as climate change or water pollution, leading an increase in human risks and well-being. Indicators have been developed determine from recreational drinking water. Still, a general application linking has not done. We here reviewed indicators indices applied assess the their links with risk evaluated extent which can witness A total 245 articles were reviewed, consisting 185 on assessment 60 Out 65 described, we use several parameters relevance evaluate risks, including physico-chemical parameters, bioindicators, contaminants, pathogens, therefore covering various sources disturbance. Based our assessment, propose set would allow inclusion well-being (e.g. coliforms, algae, pH, nutrients, chemical compounds, services). Measuring these should be incorporated into future studies understanding linkage health.

This study assessed a high Andean lake's trophic state and water quality using methodologies with eutrophication indexes. Water samples were collected at six points in the lake, monthly frequency, for three winter summer months. Dissolved oxygen, pH, phosphates, nitrates, transparency, chlorophyll-a, fecal coliforms, biological oxygen demand (BOD), temperature, turbidity determined each point. The of lake was categorized by applying Organization Economic Cooperation Development (OECD) index, Carlson's index (CTSI) (TRIX). In addition, National Sanitation Foundation (NSF-WQI), Canadian Quality Index (CCME-WQI) Oregon (OWQI) used to evaluate quality. Results indicated that had level eutrophication, suggesting an excessive accumulation nutrients water. CTSI TRIX showed hyper-eutrophic state, while according OECD methodology, related phosphorus transparency hypereutrophic, chlorophyll, it varied from mesotrophic eutrophic. NSF classified average quality, CCME fair OWQI as very poor. Therefore, andean indexes presented significant differences based on physicochemical characteristics. human influence identified main cause including tourism agriculture. These results suggest measures should be taken reduce activity area control pollution lake.

Abstract Mountain lakes are rare ecological niches supporting unique species assemblages and important sources of safe drinking water for wildlife, livestock humans. Located at high altitude, these vulnerable to environmental stressors such as climate or land-use change, impacting their ecosystem functions. However, although trends in temperature physico-chemical composition have been fairly well studied large mountain lakes, the same cannot be said small- medium-sized shallow lakes. Here, using measurements chemistry 25 Pyrenean records 14 them, we show that conditions which prevail littoral zones undergone rapid changes between 2007 2023. Over this 16-year period, found that, on average, duration ice-cover period decreased by 58.35 days, average annual rose 1.65 °C. We also a significant overall decrease pH, total organic carbon nitrogen, increase hardness dissolved potassium. Our results demonstrate abiotic alterations with potential negative implications humans, functioning. Likely consequences include declines aquatic biodiversity, degradation quality increased health risks from harmful algal blooms. Policy must urgently acknowledge impacts global change mountains order take necessary management actions.

Freshwater lakes are critical in preserving ecological balance and offering vital ecosystem services. However, mountain regions' face many issues due to natural processes anthropogenic activity. Seasonal climate change-driven events, long-range atmospheric transport, global pollution disrupt the of lakes. This study has focused on water quality Amarkantak Madhya Pradesh lakes.Amarkantak is situated Maikal Mountain range, links Vindhyachal Satpura ranges, one major tourist destinations. Water samples were collected from different region, physico-chemicalparameters wereanalyzed. The waterquality index (WQI) also calculated. results demonstrated that DO level some lower than permissible limits, BOD levels higher comparison limits occurrence eutrophication. Due increasing impact degradation, ecosystems becoming dysfunctional, which lowers theavailability clean drinking increases risks associated with habitat conditions vulnerability organisms a regional, continental, scale.To create strategies policies meet particular difficulties faced by freshwater ecosystems, policymakers, scientists, conservation practitioners can benefit greatly insights provided this study.
