Abstract Background Chemical pollution forms a severe threat for human and environmental health. While the risks European lowland water bodies are well known, there is little knowledge on remote aquatic ecosystems particularly mountain lakes, despite their importance provision of freshwater. Here, we critically review current exposure risk by chemical lakes present tiered approach how to advance effectively our understanding in future. Results Generally, pollutant monitoring data currently incomplete, with many regions substances having been only poorly investigated. More reliable exist persistent organic pollutants (POPs). However, increasing evidence that even exposed wide range pollutants. Among them potent pesticides used agricultural biocidal applications, such as diazinon permethrin. The follows complex pattern. Pollutants introduced into via atmospheric deposition run-off from watershed, but also local sources, like tourism pastoralism. Our assessment recent biomonitoring studies suggest widespread chronic toxic crustacean ranges. If ranges pastoralism, acute effects possible. Thereby, vulnerability has be expected high due harsh conditions at altitudes, organism’s traits, insular position lower species richness altitudes. Furthermore, biological processes leading degradation under ecological ecosystems. Conclusion sensitivity investigated, existing it very likely do suffer pollution-induced toxicity. To verify this suggestion expand knowledge, necessary future combine more holistic modelling links effects. Only then will possible obtain impact protect these fragile

Synthetic musks in the natural environment: Sources, occurrence, concentration, and fate-A review of recent developments (2010–2023)

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 922, P. 171344 - 171344

Synthetic musks (SMs) have served as cost-effective substitutes for natural musk compounds in personal care and daily chemical products decades. Their widespread use has led to their detection various environmental matrices, raising concerns about potential risks. Despite numerous studies on SM levels different environments, a systematic review of contemporary presence is lacking. This aims address this gap by summarising recent research developments SMs diverse including river water, lake seawater, estuarine groundwater, snow, meltwater, sediments, aquatic suspended matter, soils, sands, outdoor air, atmospheric particulate matter. Covering the period from 2010 2023, focuses four categories: nitro, polycyclic, macrocyclic, alicyclic. It systematically examines sources, occurrences, concentrations, spatial temporal variations, fate. The literature reveals environment (freshwater sediments particular), with polycyclic being most studied group. Both direct (e.g., wastewater discharges) indirect human recreational activities) sources contribute presence. Levels vary greatly among higher observed certain regions, such Southeast Asia. Spatial variations are also evident. fate depends physicochemical properties processes, bioaccumulation, biodegradation, photodegradation, adsorption, phase exchange, hydro-dilution effects. Biodegradation photodegradation can decrease levels, but may produce more persistent eco-toxic products. Modelling approaches been employed analyse fate, especially processes like or long-distance transport. Future should further investigate complex if influence. enhances understanding status supports efforts control contamination.

Atmospheric Transport of Polycyclic Aromatic Hydrocarbons into Three Alpine Valleys: Influence of Local-Scale Wind Patterns and Chemical Partitioning

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(35), P. 13114 - 13123

Published: Aug. 22, 2023

Current understanding of atmospheric transport polycyclic aromatic hydrocarbons (PAHs) is limited in alpine areas due to complex meteorology and topography. To better understand these areas, we measured 16 PAHs lichens, biomonitors PAHs, along three transects extending from a highway into otherwise remote valleys. While the valleys neighbored one another were morphologically similar, they differed their orientation relative regional winds. In valley characterized by winds oriented up-valley, PAH concentrations lichens remained consistent across transect. other two valleys, where down or valley, 3–6 ring declined rapidly with increasing distance highway, more for higher molecular weight than lower PAHs. We hypothesize that this trend was driven differences gas-particle partitioning vegetative scavenging between congeners. These results illustrate importance both physical chemical small topography can lead significant transport.

Ecological interactions in glacier environments: a review of studies on a model Alpine glacier

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 9, 2024

ABSTRACT Glaciers host a variety of cold‐adapted taxa, many which have not yet been described. Interactions among glacier organisms are even less clear. Understanding ecological interactions is crucial to unravelling the functioning ecosystems, particularly in light current retreat. Through review existing literature, we aim provide first overview biodiversity, primary production, trophic networks, and matter flow ecosystem. We use Forni Glacier (Central Italian Alps) – one best studied alpine glaciers world as model system for our literature integrate additional original data. reveal importance allochthonous organic inputs, Cyanobacteria eukaryotic green algae key role springtails ( Vertagopus glacialis ) on surface sustaining populations two apex terrestrial predators: Nebria castanea (Coleoptera: Carabidae) Pardosa saturatior (Araneae: Lycosidae).

This short food web highlights fragility nodes represented by invertebrates, contrasting with structured microbial communities all habitats. Although further research necessary quantify organisms, this summarises integrates knowledge about processes supports glacier‐adapted providing ecosystem services.
