Review: mountain lakes as freshwater resources at risk from chemical pollution

Environmental Sciences Europe, Journal Year: 2023, Volume and Issue: 35(1)

Published: Jan. 13, 2023

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

Vessel Operations in the Arctic, 2015–2017

Frontiers in Marine Science, Journal Year: 2019, Volume and Issue: 6

Published: Sept. 18, 2019

The Arctic is among the most rapidly-changing regions on Earth. Diminishing levels of sea-ice has increased opportunities for maritime activities in historically inaccessible areas such as Northern Sea Route and Northwest Passage. Degradation marine ecosystems may accompany expanding vessel operations through introduced underwater noise, potential large oil spills, other things; compound stressors already effecting biological populations due to climate change. Assessments are needed track changes traffic patterns associated environmental impacts. We analyzed Arctic-wide Automatic Identification System data 1 January 2015-31 December 2017 quantify amount spatial distribution operations, assess possible these establish a baseline future monitoring. Nearly 400,000 transits were analyzed. Number trips, hours operation, sea surface exposed used compare between 14 delineated waterways. Operations extensive diverse: an average 132,828 trips made annually by over 5,000 different vessels. Transits all studied months year. Maritime intensive some areas, but ice-limited others. Amount exceeded 70% three areas. Bulk carriers, cargo ships, passenger/cruise research survey vessels supporting oil/gas-related represented. However, fishing vessels, primarily Barents, Bering, Norwegian Seas, surpassed types comprised about one-half voyages each observed no overt increasing or decreasing trends volume our limited study period. Instead, inter-year variation was evident. While number unique year-to-year, operation declined same Abundance/distribution fisheries resources, economic feasibility travel weighed against inherent risks, factors likely accounted regional activity levels. Measures have been established protect need strengthening address ecosystem threats from existing growing commercial industrial region.

Petroleum spill bioremediation by an indigenous constructed bacterial consortium in marine environments

Ecotoxicology and Environmental Safety, Journal Year: 2022, Volume and Issue: 241, P. 113769 - 113769

Published: June 20, 2022

In the process of marine oil spill remediation, adding highly efficient degrading microorganisms can effectively promote degradation. However, in practice, effect is far less than expected due to inadaptability environment and their disadvantage competition with indigenous bacteria for nutrients. this article, four strains were isolated from seawater Jiaozhou Bay, China, where a crude pipeline explosion occurred seven years ago. Results high-throughput sequencing, diesel degradation tests surface activity indicated that Peseudomonas aeruginosa ZS1 was petroleum bacterium ability produce active substances. A oil-degrading bacterial consortium (named SA) constructed by another test. Degradation products analysis SA has good degrade short chain alkanes, especially n-alkanes (C10-C18). Community structure showed OTUs Alcanivorax, Peseudomona, Ruegeria, Pseudophaeobacter, Hyphomonas Thalassospira on genus level increased after remained stable throughout recovery period. Most these enriched related known alkane hydrocarbon degraders previous study. it first time report Pseudophaeobacter using as sole carbon source. The results also may have dominant position bacteria. Oil pollution an obvious selective microorganisms. Although promoted injection, microbial community took longer time.

Depletion of crude oil and fuel in the Arctic. Summer and winter field studies with immobilized oil in seawater at Svalbard

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 971, P. 179043 - 179043

Published: March 1, 2025

Seasonal dynamics can vastly influence the natural depletion of oil spilled into ocean and Arctic regions are characterized by large seasonal changes, especially in temperature daylight. To determine influences variation on processes like dissolution, photooxidation biodegradation, we deployed thin films three oils seawater during summer winter Svalbard, Norway. The extent varied with season type oil, however, considerable n-alkanes polycyclic aromatic compounds were observed both winter. components was not consistent between only small effects found summer. We further variations composition bacterial communities associated seasons an apparently delayed succession generally contained high abundances previously reported degrading taxa which displayed distinct patterns their relative abundance. Oleispira Oleibacter dominantly Colwellia winter, while Cycloclasticus C1-B045 highly abundant seasons. While environmental factors likely cause for oils, differences community did seem to affect biodegradation potential.
