    Jellyfish are known for experiencing periodic blooms in population, which occur when their density increases suddenly. The present study assessed the level of heavy metals and proximate composition in the jellyfish Lobonemoides robustus collected from Cox's Bazar coast of Bangladesh. This is the first study conducted in Bangladesh. Most of the studied metals were not possible to detect in L. robustus samples because concentrations were below the detection limit. Ca, Na, Se, and Mg were found to have safe levels in the L. robustus while the amount of Pb was recorded 0.39 ppm. The findings of Target Hazard Quotient, and Carcinogenic Risk indicate that the L. robustus is safe for human consumption (both for children and adults). Hence, it is suitable for consumption and can be exported. This study emphasizes the need for regular marine environment monitoring to ensure that the seafood harvested from these waters is safe for consumption.

    Heavy metal and mineral analysis of cultivated seaweeds from Cox’s Bazar Coast, Bay of Bengal, Bangladesh: a human health risk implication
    (Discover Oceans, 2024-06-24) Bhuyan, Md. Simul; Kunda, Mrityunjoy; Bakar, Muhammad Abu; Senapathi, Venkatramanan; Husain, Sk. Abid; Chowdhury, Enam; Ali, Mir Mohammad; Pandit, Debasish
    Seaweeds are grown for their use in food and other sectors, however heavy metals (HMs) contamination raises serious issues for the environment and public health. This study focuses on seaweed samples (Hypnea musciformes and Gracilaria lemaneiformis) collected from the Rezu Khal seaweed culture site, Cox’s Bazar coast, Bangladesh. HMs and minerals were determined using Atomic Absorption Spectrophotometry (AAS). Among the elements examined, H. musciformes displayed the highest mean concentrations of minerals and HMs, including Magnesium (Mg) (8663.00 ±2302.06 mg/kg), Copper (Cu) (10.59±1.61 mg/kg), Iron (Fe) (7566.29±2842.47 mg/kg), Manganese (Mn) (9.93±2.88 mg/kg), Zinc (Zn) (29.54±7.51 mg/kg), and Nickel (Ni) (11.77±2.63 mg/kg). Conversely, G. lemaneiformis exhibited the highest levels of Calcium (Ca) (798.14±143.40 mg/kg), Lead (Pb) (3.91±1.74 mg/kg), and Chromium (Cr) (0.59±0.30 mg/kg). Specifically, Mg was prominently abundant in H. musciformes, while Cawas more prevalent in G. lemaneiformis. Both seaweed types contained Pb and Cr. None of the elements was significantly different between the species (p <0.05). The consumers are not exposed to any carcinogenic or non-carcinogenic risks related to these concentrations, according to the evaluation of carcinogenic and non-carcinogenic risks.
