Role of marine algal blooms in the release of arsenic at the …
Oct 1, 2023 · We investigated algal bloom effects on sediment-water interface arsenic dynamics. Algal blooms aggravated sedimentary arsenic release, posing a marine pollution risk. The main arsenic release pathway was microbially rather than geochemically mediated.
Influence of algal blooms decay on arsenic dynamics at the sediment ...
Mar 1, 2019 · Algal blooms decay affects the mobility, bioavailability, and toxicity of arsenic (As) in aquatic environments. The decaying process alters aquatic redox conditions and also introduces ample organic matter, conditions favorable for microbial reduction to simulate As release and As species transformation.
Degradation of algae promotes the release of arsenic from …
Feb 1, 2024 · Algal decomposition at high sulfate concentration produced a synergistic effect on As release, anaerobic environments formed by the degradation of algae led to the reduction of Fe/Mn-oxides, and dissolution of arsenic sulfide was the main cause of As release.

Aug 1, 2023 · Algal blooms can aggravate arsenic (As) release from sediments and thus pose a pollution risk in the marine environment. However, the driving mechanism of algal blooms on sedimentary As...
Risk Assessment and Source Identification of Arsenic in Surface ...
Given that many urban eutrophic freshwater sources are important for drinking water, as well as industrial and agricultural needs, it is necessary to monitor the As level and speciation in sediments to comprehensively assess their As ecological risk during the algal blooms period.
The variations of labile arsenic diffusion driven by algal bloom ...
Oct 10, 2022 · The vertical labile arsenic (As) concentration and diffusion pattern variations in eutrophic lakes were investigated using in situ techniques of diffusive gradients in thin films (DGT) and high-resolution dialysis (HR-Peeper) in the typical eutrophic system of Lake Taihu in China.
Influence of algal blooms decay on arsenic dynamics at the sediment ...
Dec 1, 2018 · Algal blooms decay affects the mobility, bioavailability, and toxicity of arsenic (As) in aquatic environments. The decaying process alters aquatic redox conditions and also...
The variations of labile arsenic diffusion driven by algal bloom ...
Jun 1, 2022 · Recent research suggests that eutrophication and climate change are two processes that may promote the proliferation and expansion of cyanobacterial harmful algal blooms.
Trace Metals in Phytoplankton: Requirements, Function, and
Jun 7, 2024 · Eutrophication has been identified as one of the major culprits of algal bloom events since macronutrients from agricultural runoff and aquaculture waste, including nitrogen, phosphorus, and to some extent silica, play critical roles in the species-specific bloom dynamics of phytoplankton species.
