A eview of the literature revealed that bioaccumulation of silver in soil is rather low, even if the soil is amended with silver‐containing sewage sludge. Plants grown on tailings of silver mines were found to have silver primarily in the root systems. In marine and freshwater systems, the highest reported bioconcentration factors (BCFs) were observed in algae (>105), probably because of adsorption of the dissolved silver (<0.45 μm fraction) to the cell surface. In herbivorous organisms (e.g… 
Biochemical and Physiological Effect of Silver Bioaccumulation
Silver displays different extents of bioaccumulation depending on the ecosystem involved, and literature has shown that by means of physiological and biochemical effects, silver bio Accumulation gives rise to both benign and harmful disease.
Using amphipods as bioindicators of metal pollution in the marine environment
Heavy metals in the marine environment are a worldwide issue due to their toxicity, non-biodegradability and their ability to accumulate and magnify in organisms. Increased human activity has caused
Effects of ligand‐bound silver on Ceriodaphnia dubia
Results indicate that the ligand-bound silver in these laboratory studies is bioavailable and impairs reproduction of C. dubia at low aqueous concentrations.
The effect of soil properties on the toxicity of silver to the soil nitrification process
Soil pH and organic carbon were the properties found to have the greatest influence on the variations in toxicity thresholds across the soils, and significant relationships were developed that accounted for approximately 90% of the variability in the data.
Rhizotoxic effects of silver in cowpea seedlings
It is shown that Ag (as Ag+) is rapidly rhizotoxic to cowpea seedlings at concentrations similar to those that are toxic to freshwater biota and the similarity of rupturing effects suggests a distinctive metabolic effect of Ag that binds only weakly to hard ligands.
Predictability of silver nanoparticle speciation and toxicity in ecotoxicological media
The use of silver nanoparticles (AgNPs) as an antimicrobial agent has increased significantly over the past decade which potentiates their release to the environment. The antimicrobial effect of
Effects of silver nanoparticles on survival , biomass change and avoidance behaviour of the endogeic earthworm
Comparisons with studies employing Eisenia fetida and Eisenia andrei suggest that the A. chlorotica response to Ag NP is more sensitive, and further research employing both epigeic and endogeic earthworms under similar experimental conditions is required to confirm this observation.


Partitioning and effects of silver in amended freshwater sediments.
Sediments that represented a wide range of characteristics were amended with silver compounds to observe partitioning and bioavailability, and silver chloride and silver thiosulfate were orders of magnitude less toxic and bioavailable than silver nitrate.
Toward a better understanding of the bioavailability, physiology, and toxicity of silver in fish: Implications for water quality criteria
In its ionic form, silver (Ag+) is highly toxic to fish (96‐h 50% lethal concentration [LC50]: low μg/L range). However, concentrations of Ag+ in aquatic environments are extremely low and other more
Silver Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
Abstract : Ecological and toxicological aspects of silver (Ag) and silver salts in the environment are briefly summarized with an emphasis on natural resources. Elevated silver concentrations in
Toxicity of silver sulfide‐spiked sediments to the freshwater amphipod (Hyalella azteca)
Natural freshwater sediments were spiked in the laboratory with silver sulfide (Ag2S), and semistatic toxicity tests were conducted, indicating that this form of silver was not bioavailable under these conditions.
Toxicity and fate of silver in the environment
The results of research funded by the Silver Coalition (1991–1995) and The Silver Council (1996 to present) on the behavior of silver in various environmental media have been presented at a series of
Trophic transfer of silver to marine herbivores: A review of recent studies
We review recent progress in understanding the trophic transfer of silver (Ag) in marine herbivores, especially mussels that have been extensively used as biomonitors of coastal contamination. A
Bioaccumulation of silver from laboratory‐spiked sediments in the oligochaete (Lumbriculus variegatus)
This low accumulation factor indicates that contamination of sediments with silver sulfide does not pose a major route of entry of silver into the aquatic food web.
Transport, Fate and Effects Of Silver In The Environment
Inorganic and organic components of water influence silver speciation in waste water effluent and may affect silver toxicity. Cationic and anionic constituents of aqueous systems control ionic
