“…Sensitivity analyses indicate that in addition to Se, other elements, including As, V and Co, may also be derived from marine productivity. These elements have been found to be enriched in biogenically derived organic compounds in marine surface waters. − For example, Klein et al found a positive correlation between intracellular V concentration and chlorophyll a ( R 2 = 0.49, P < 0.05) in marine surface waters during an algal bloom in the eastern North Atlantic, indicating that marine organisms are a potential primary source of atmospheric V. Also for As there is a clear link with marine organisms. The formation and excretion of organic As compounds such as monomethylarsenic (MMAs) and dimethylarsenic (DMAs) by marine organisms is relatively well-known (e.g., refs , , , and ).…”

Atmospheric processes play an important role in the supply of the trace element selenium (Se) as well as other essential trace elements to terrestrial environments, mainly via wet deposition. Here we investigate whether the marine biosphere can be identified as a source of Se and of other trace elements in precipitation samples. We used artificial neural network (ANN) modeling and other statistical methods to analyze relationships between a high-resolution atmospheric deposition chemistry time series (March 2007-January 2009) from Plynlimon (UK) and exposure of air masses to marine chlorophyll a and to other source proxies. Using ANN sensitivity analyses, we found that higher air mass exposure to marine productivity leads to higher concentrations of dissolved organic carbon (DOC) in rainfall. Furthermore, marine productivity was found to be an important but indirect factor in controlling Se as well as vanadium (V), cobalt (Co), nickel (Ni), zinc (Zn), and aluminum (Al) concentrations in atmospheric deposition, likely via scavenging by organic compounds derived from marine organisms. Marine organisms may thus play an indirect but important role in the delivery of trace elements to terrestrial environments and food chains.

“…163 The accumulation of V was also detected in small phytoplankton (>20 μm) at Cabo Frio, Rio de Janeiro state, Brazil, with concentrations reaching 49.0 mg/kg. 164 However, the current knowledge regarding V hyperaccumulators is limited compared to that of hyperaccumulators of other metals. 165 There is also a lack of a widely accepted reference standard for V accumulation.…”

“…In marine ecosystems, analysis of samples from the vegetated littoral zone of the Indian Sundarbans suggests that mangroves can accumulate V, with a translocation factor up to 5.1 . The accumulation of V was also detected in small phytoplankton (>20 μm) at Cabo Frio, Rio de Janeiro state, Brazil, with concentrations reaching 49.0 mg/kg .

“…Kütter et al used SEC and AEC-UV-ICPMS as well as matrix-assisted laser desorption/ionization (MALDI) time of flight mass spectrometry for V speciation analysis in plankton. 59 They found a V-containing compound with a mass of 8-16 kDa, but concluded that it was not possible to further identify this compound. Finally, in 1987, Koch et al used ion-pair chromatography with UV detection to determine amavadin in different parts of Amanita muscaria, as already described earlier.…”
