The journal publishes original research articles dealing with all aspects of marine science and coastal management. Topics include, but are not limited to: theoretical studies, oceanography, marine biology and ecology, fisheries, recovery and restoration processes, legal and institutional frameworks, and interactions/relationships between humans and the coastal and marine environment. In addition, <em>Western Indian Ocean Journal of Marine Science </em>features state-of-the-art review articles and short communications. The journal will, from time to time, consist of special issues on major events or important thematic issues. Submitted articles are subjected to standard peer-review prior to publication.</p> <p>Journal abbreviation: WIO J. Mar.

<div class="page" title="Page 1"> <div class="layoutArea"> <div class="column"> <p>There has been little research on heavy metals and aflatoxins in Tanzanian seaweeds. Concentra- tions of lead (Pb), cadmium (Cd), total mercury (THg), and methyl mercury (MeHg) were meas- ured in cottonii (Kappaphycus alvarezii) and spinosum (Eucheuma denticilatum) seaweeds from Tanzania. Seaweeds were collected in February 2024 from Tanga, Pwani, and North Unguja. Inductively coupled plasma optical emission spectroscopy (ICP-OES) was used to assess Cd and Pb, a direct mercury analyzer (DMA-80) was used to analyze THg and MeHg, and high-perfor- mance liquid chromatography was used to determine anti-aflatoxigenic activity. Heavy metal concentrations were highest for Cd, followed by Hg, Pb and MeHg, and varied significantly (p&lt;0.05) between species and sampling locations. The concentrations of Cd, Pb, and MeHg were below safety thresholds set by the European Union and Codex Standard, while THg concentra- tions exceeded Codex limits but were within European Union limits, and can therefore safely be consumed. Aflatoxins were not detected in the seaweed samples. Further research on heavy metal concentrations and moisture stability in Tanzanian seaweeds is recommended, over a period of at least a year.</p> </div> </div> </div>
