Concern about metals and metalloids, especially heavy metals in seaweeds has risen due to potential health risk. This study investigated the distribution of 10 metals and metalloids in 295 dried seaweeds (brown and red) and estimated the possible health risk via hazard index (HI). Elements in seaweeds can be sequenced in descending order by mean values: Al > Mn > As > Cu > Cr > Ni > Cd > Se > Pb > Hg. The levels of Cd, Cu, Mn and Ni in red seaweeds were significantly higher than those in brown seaweeds (P < 0.01). Correlation analysis showed contents of Ni-Cr (r = 0.59, P < 0.01) in seaweeds had moderate positive correlations. Seaweeds from different geographical origins had diverse element distribution. Risk assessment showed that HI at mean level was less than the threshold of 1. It indicates that for the general people there is low health risk to these elements by the intake of seaweeds. Furthermore, in terms of the confirmative toxicity of some metals, such as Cd, Pb and Hg, surveillance of metals in seaweeds should be performed continuously.

“…A characteristic feature of Potter Cove is that particulate Fe content at 0 m near the glacier in Island D is significantly higher than in Peñón de Pesca (Table 3). The morphology and structure of macroalgae seem to determine Fe uptake capacity, since minerals and trace elements concentrations differ among seaweeds (Astorga-España et al, 2015), also in Antarctica (Farías et al, 2002). Suzuki et al (1995) reported that in Japanese coastal areas where Fe concentrations were extremely low (b 2 nM), the ecosystem was dominated by a red coralline algae (Lithophyllum) while a brown macroalgae was prevented from growing.…”

“…Seaweeds are rich sources of minerals (8-40%) due to their capacity to absorb inorganic substances from the surrounding marine media and store them in their tissues [1]. Seaweed mineral compositions vary according to phylum, environmental (geographic location, season, wave exposure, seawater temperature, salinity, mineral levels in seawater, and the pH of seawater among other factors) and physiological conditions [2,3]. Moreover, a determining factor for mineral uptake by seaweeds is the content and type of polysaccharides in the cell wall structure [4].…”

Development of New Canned Chub Mackerel Products Incorporating Edible Seaweeds—Influence on the Minerals and Trace Elements Composition

et al. 2020

This study aimed to develop new canned chub mackerel products incorporating edible seaweeds (Ascophyllum nodosum, Fucus spiralis, Saccorhiza polyschides, Chondrus crispus, Porphyra sp. and Ulva sp.) harvested in the Portuguese North-Central coast, with simultaneous sensory improvement and minerals enrichment. Two processes were compared, namely the addition of seaweeds in i) the canning step and ii) in the brining step (as the replacement for salt). The concentrations of four macrominerals (Na, K, Ca and Mg), chloride, and twelve trace elements (Co, Cu, Fe, I, Li, Mn, Mo, Rb, Se, Sr, V and Zn) were determined by high-resolution continuum source flame atomic absorption spectrometry (HR-CS-FAAS) and inductively coupled plasma mass spectrometry (ICP-MS), respectively. Results showed that canned chub mackerel incorporating C. crispus and F. spiralis was found to be the preferred sensory option, also exhibiting contents enriched with Cl, Co, Cu, Fe, I, Li, Mg, Mn, Mo, Na, Rb, Se, and Sr. This effect was more pronounced when both seaweed species were added to replace the salt added in the brining step.
