“…It was reported that the polychaete species S. spallanzanii from the coastal regions of Australia can produce DMA by methylating iAs or demethylating more complex arseno-compounds. Results of feeding experiments supported the speciesspecific function of arsenic making unpalatable to predators the more vulnerable tissues (Fattorini et al 2004;Notti et al, 2007). A similar defensive role can be proposed for the marked accumulation of vanadium in branchial crowns of P. littoralis which were also vigorously rejected by fish after tasting these tissues.…”

Abstract:This paper documents the concentration of total arsenic and individual arsenic species in four soft-bottom benthic polychaetes (Perenereis cultifera, Ganganereis sootai, Lumbrinereis notocirrata and Dendronereis arborifera) along with host sediments from Sundarban mangrove wetland, India. An additional six sites were considered exclusively for surface sediments for this purpose. Polychaetes were collected along with the host sediments and measured for their total arsenic using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Arsenic concentrations in polychaete body tissues varied greatly, suggesting speciesspecific characteristics and inherent peculiarities in arsenic metabolism. Arsenic was generally present in polychaetes as arsenate (As V ranges from 0.16 -0.50 mg kg -1 ) or arsenite (As III ranges from 0.10 -0.41 mg kg -1 ) (30 to 53% as inorganic As) and dimethylarsinic acid (DMA V ; <1 to 25%). Arsenobetaine (AB; <16%), and PO 4 -arsenoriboside (8 to 48%) were also detected as minor constituents, whilst monomethylarsonic acid (MA V ) was not detected in any of the polychaetes. The highest total As (14.7 mg kg -1 dry wt) was observed in the polychaete D. arborifera collected from the vicinity of a sewage outfall in which the majority of As was present as an uncharacterized compound (10.3 mg kg -1 dry wt) eluted prior to AB. Host sediments ranged from 2.5 to 10.4 mg kg -1 total As. This work supports the importance of speciation analysis of As, because of the ubiquitous occurrence of this metalloid in the environment, and its variable toxicity depending on chemical form. It is also the first work to report the composition of As species in polychaetes from the Indian Sundarban wetlands.

“…DMA is a relatively toxic organo-As compound for marine organisms (Fattorini et al 2004;. Notably, DMA in sediments was either absent or inconsistently present in low concentrations, whereas this was almost consistently present in all polychaete body tissues.…”

The closed anaerobic decomposition extracts of Fucus distichus incubated with seawater and sediment, and without sediment as control, were subjected to extractions and isolation on Sephadex LH 20 and Cellulose Thin Layer Chromatography. The decomposition extracts and isolates were analyzed by using both the Hydride Generation Gas Chromatography Atomic Absorption Spectrometry (HG-GC-AAS) and High Performance Liquid Chromatography Inductively Coupled Plasma Mass Spectrometry (HPLC-ICPMS) to identify the arsenic species in the equilibrium mixtures of the seaweed and filtrates separately. In the methanol seaweed extract, equilibrium mixture of arsenosugars (AS) AS1 and AS2 and their biotransformation products of dimethylarsinoylethanol (DMAE) and dimethylarsinic acid (DMAA) were identified. In the methanol filtrate extract of the mixture, only DMAE and DMAA were identified. However, in the control methanol filtrate extract five organoarsenic species, AS1 and AS2, one unidentified hidden organoarsenic species, DMAE and DMAA were identified in the equilibrium mixture. This result confirmed that the hidden organoarsenic species in Fucus distichus, AS1 and AS2, and an unidentified organoarsenic compounds are biotransformed to only DMAE and DMAA under an anaerobic condition. This also suggests that DMAE and DMAA are strong intermediate candidates for the generation of arsenobetaine, from arsenoribosides in the marine food webs.

“…Water is one of the most important sources of natural As from wells dug in soil with a rich content of inorganic As due to geological reasons [51,55,57,58]. Foods with the highest content of As include some marine organisms like shellfish and crustaceans, which contain both inorganic As, at percentages ranging from 1% to 41%, and organic As [dimethylarsinic acid (DMA), arsenobetaine, arsenosugars, arsenolipids, and low concentrations of monomethylarsonic acid (MMA) and arsenocholine] [59][60][61][62][63][64][65][66][67]. Inorganic As is absorbed more slowly by inhalation than by ingestion [68].…”
