“…From these results, a relationship between the arsenic concentration levels and the alga species or their origin cannot be established. Algae absorb arsenic directly from sea water and there are some factors influencing the arsenic levels in these marine organisms, such as the light intensity, turbidity, temperature, depth, salinity and nutrient uptake [21]. These factors may contribute to the differences observed in total arsenic concentration levels in the algae studied.…”

Keywords:Arsenic speciation Microwave-assisted extraction Edible algae Inductively coupled plasma atomic emission spectrometry High performance liquid chromatography Hydride generation-atomic fluorescence spectrometry Twelve commercially available edible marine algae from France, Japan and Spain and the certified reference material (CRM) NIES No. 9 Sargassum fulvellum were analyzed for total arsenic and arsenic species. Total arsenic concentrations were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) after microwave digestion and ranged from 23 to 126 (xgg -1 . Arsenic species in alga samples were extracted with deionized water by microwave-assisted extraction and showed extraction efficiencies from 49 to 98%, in terms of total arsenic. The presence of eleven arsenic species was studied by high performance liquid chromatography-ultraviolet photo-oxidation-hydride generation atomic-fluorescence spectrometry (HPLC-(UV)-HG-AFS) developed methods, using both anion and cation exchange chromatography. Glycerol and phosphate sugars were found in all alga samples analyzed, at concentrations between 0.11 and 22 (xgg -1 , whereas sulfonate and sulfate sugars were only detected in three of them (0.6-7.2 (xgg -1 ). Regarding arsenic toxic species, low concentration levels of dimethylarsinic acid (DMA) (<0.9 (xgg -1 ) and generally high arsenate (As(V)) concentrations (up to 77 (xgg -1 ) were found in most of the algae studied. The results obtained are of interest to highlight the need to perform speciation analysis and to introduce appropriate legislation to limit toxic arsenic species content in these food products.

Arsenic accumulation in intertidal macroalgae exposed to sewage discharges

Arsenic is a widely distributed element in marine ecosystems. The main anthropogenic sources of this contaminant are domestic and industrial wastewaters, and since it can be harmful to humans even at low concentrations, it has been ranked as one of the top hazardous substances. Therefore, the analysis of arsenic is an essential task to assess the potential environmental and human health risk associated with sewage discharges. The accumulation of total arsenic on intertidal rocky shore macroalgae exposed to contaminated sewage discharges was measured in five macroalgae species (Asparagopsis armata, Codium sp., Plocamium cartilagineum, Saccorhiza polyschides and Ulva sp.). Differences in the concentrations of arsenic were examined in the seawater and in the macroalgae species. The results showed significantly higher concentrations of arsenic near the sewage discharges in all the species except S. polyschides. Although the information obtained from total arsenic determination is not enough to assess the toxicological risk in the environment, this paper gives an important contribution on contamination risks and helps in choosing potential good biomonitors.
