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.

对从科克斯巴扎尔海岸收集的水母（Lobonemoides roughtus Stiasny，1920）中的重金属和近似成分进行评估：人类健康风险评估


众所周知，水母会经历周期性的种群数量激增，这种情况发生在它们的密度突然增加时。本研究评估了从孟加拉国考克斯巴扎尔海岸收集的 Lobonemoides roughtusus 水母中的重金属水平和近似成分。这是在孟加拉国进行的第一项研究。大多数研究的金属无法在粗壮乳杆菌样本中检测到，因为浓度低于检测限。粗壮乳杆菌中的 Ca、Na、Se 和 Mg 含量均达到安全水平，而 Pb 含量为 0.39 ppm。目标危险商数和致癌风险的结果表明，粗壮乳杆菌对于人类食用（儿童和成人）是安全的。因此，它适合消费并可以出口。这项研究强调需要定期监测海洋环境，以确保从这些水域捕获的海鲜可以安全食用。
