The biogeochemical cycling of mercury in aquatic environments is a complex process driven by various factors, such as ambient temperature, seasonal variations, methylating bacteria activity, dissolved oxygen levels, and Hg interaction with organic matter (DOM). As consequence, part the contamination from anthropogenic activity that was buried sediments reinserted into water columns mainly highly toxic forms (methylmercury, dimethylmercury, etc.). This especially prominent coastal shallow waters industrial regions worldwide. main entrance point these food web naturally occurring phytoplankton. availability, intake, effect on population size, cell toxicity, eventual biotransformation, intracellular stability phytoplankton are greatest importance for human health, having mind incorporated inside cells due to biomagnification effects eventually ends up wildlife, fish, seafood, diet. review summarizes recent findings topic form natural offers new insight possible directions future research prevention scope climate change global pollution increase scenarios.

Anthropogenic activities have been releasing mercury for centuries, and despite global efforts to control emissions, concentrations in environmental media remain high. Coastal sediments can be a long-term repository mercury, but also secondary source, competing processes marine ecosystems lead the conversion of into toxic bioaccumulative species methylmercury, which threatens ecosystem human health. We investigate fate transport three coastal lagoon affected by historical pollution using novel high-resolution finite element model that integrates biogeochemistry, sediment dynamics hydrodynamics. The resolves seawater seabed taking account partitioning, driven water sediment, photochemical microbial transformations. simulated years (early 2000s, 2019, 2020) assess spatio-temporal distribution performed sensitivity analysis uncertainties. modeled show high temporal spatial variability, with some areas exceeding those open Mediterranean Sea two orders magnitude, consistent available observations from early 2000s. results support conclusions about importance different shaping gradients species.

The main drivers of mercury (Hg) compound distribution in seawater are poorly understood, calling for novel spatial and seasonal observations potential transformations. However, scientific progress is hindered by a lack intercomparability among incubation studies the infrequent inclusion dissolved gaseous species (DGM = elemental Hg (Hg(0)) + dimethyl (DMHg)) despite their importance biogeochemical cycle Hg. We perform comprehensive quality assessment on our proposed protocol at near ambient concentrations (∼10 × background) including formation DGM three distinct coastal seawaters discuss with previous experimental approaches. establish an excellent mass balance tracer isotopes both excluding (199Hg 99.5% 201Hg 100.4%, median) 100.3% 101.7%, median). find good median relative standard deviation triplicates (199Hg(II) ∼ 1.7%, MM201Hg 1.5%, 199DGM 10%, 201Hg(II) 13%, 201DGM 22%), enabling accurate determination methylation, demethylation, reduction rate constants femtomolar concentration levels. observed Hg(0) from MMHg, potentially indicating reductive demethylation. This study highlights practicability incorporating (here, Hg(0), eventually DMHg) future studies.
