About 50 000 tons of chemical weapons (CW) were dumped to the Baltic Sea after Second World War. Munitions are located in deep areas Sea, and there they act as a point source contamination ecosystem. Corroded munitions release warfare agents (CWAs) nearby water sediments. In this study we investigated known dumpsites (Bornholm, Gotland Gdansk Deep) dispersed munitions, evaluate extent sediments, well assess degradation process released CWA. It was found that CWA-related phenylarsenic...
Sea dumping of chemical warfare (CW) took place worldwide during the 20th century. Submerged CW included metal bombs and casings that have been exposed for 50–100 years corrosion are now known to be leaking. Therefore, arsenic-based agents (CWAs), pose a potential threat marine ecosystems. The aim this research was support need real-data measurements accurate risk assessments categorization threats originating from submerged CWAs. This has achieved by providing broad insight into CWAs acute...
In Mediterranean seas and coastal zones, rivers can be the main source of mercury (Hg). Catchment management therefore affects load Hg reaching sea with surface runoff. The major freshwater inflows to Baltic Sea consist large rivers. However, their systems are complex identification factors affecting outflow from its catchments is difficult. For this reason, a study into impact watershed land use season on biogeochemistry transport in was performed along two small which may considered...
Arsenic is a ubiquitous chemical element, occurring naturally worldwide. Yet due to its global cycle, concentrations in the marine environment are manifold higher than terrestrial background and may pose harm biota. This especially relevant for Baltic Sea, which very susceptible any kind of pollution. transported sea adsorbed on iron oxides or precipitating as flocculating particulates finally bounded sediments. Therefore, despite contemporary emission cuts, existing pollution remains...
The sea bottom acts as a key natural archive where the memory of long-term timescale environmental changes is recorded. This study discusses some ecological and chemical features fjord sediments that were explored during AREX cruise carried out in Svalbard archipelago summer 2021. activity rates enzymes leucine aminopeptidase (LAP), beta-glucosidase (GLU), alkaline phosphatase (AP) community-level physiological profiles (CLPPs) studied with aim determining functional diversity benthic...
Methylmercury (MeHg) is the most toxic and dangerous form of mercury occurring in environment. MeHg highly bioaccumulative organisms undergoes biomagnification via food chain. In Baltic Sea munition dumpsites, methylmercury can be formed from fulminate contained primary explosives, as environmental conditions there favour methylation. analysed sediments ranged 19 to 2362 pg g-1d.w., concentration (HgTOT) 4 294 ng g-1 d.w., values MeHg/Hg ratio 0.1 2.0%. The obtained results confirmed that...
Abstract This study presents total mercury concentrations (HgT) in selected tissues and organs (blood, muscles, liver, kidneys, feathers claws) of the herring gull (Larus argentatus) order to assess environmental pollution coastal zone southern Baltic. Dead, frozen birds were collected vicinity Wladysławowo between December 2009 March 2010, an exceptionally severe winter — a 13 specimens; 6 adults (>4 years old) 7 immature (≤4 old). Mercury all analyzed samples exceeded detection limit....
Abstract Purpose Mercury speciation in sediments is linked to environmental conditions and processes. Domination of particular mercury species depends on its source, displays considerable seasonal behavior, may be further modified due oxygen levels, icing conditions, or the input fresh organic matter. The purpose this study was examine coastal area Gulf Gdańsk terms contamination influence changes speciation. Materials methods In three highly dynamic sites, studied relation other parameters...
Mercury, despite of its many uses in industry, is also highly toxic. It neurotoxic, and because the ability mercury to penetrate placental barrier, some countries ban on predatory fish consumption (the main route into human organism) by pregnant women was introduced. There are very little publications describing consequences weather anomalies contaminants cycles. No research published concerning reemission Hg due climate change Southern Baltic Sea. The study area situated coastal zone Gulf...
Every year, huge amounts of bottom sediments are extracted worldwide, which need to be disposed. The recycling for soil fertilization is in line with the long-promoted circular economy policy and enables use micro macronutrients accumulated fertilization. When considering potential agricultural reuse dredge sediments, first necessary step should analyze whether heavy metal content meets obligatory criteria. Then, contents valuable elements required plant growth their ratios assessed. In this...
Arsenic concentration in marine areas are higher than terrestrial environment, because most of its compounds water soluble, and bodies serve as a sink for this element. compounds, though naturally present the sediments, considered threat to due possible transformation toxic species – As3+ As5+. Natural background arsenic is highly variable, it differs both with type presence ferromanganese nodules, iron sulphides or proximity sources. In Baltic Sea, majority As originates from river runoff,...
