Ulva intestinalis (UI) is widely available edible seaweed and has potential to be introduced as functional food items in Bangladesh. However, potential health hazards of this seaweed with biotoxicity assays and its relation to heavy metal contents were not evaluated previously. With these objectives, toxic effects of UI collected from floating raft culture in Monkhali Beach was evaluated using various organisms such as Chlorella vulgaris, Artemia salina, Daphnia magna, and Lactuca sativa. In relation to this effects, heavy metal concentrations (Fe, Cr, Ni, Cu, Zn, Pb, Cd, and As) and its potential health hazards were subsequently analyzed. The results showed that UI water extract had positive effects on the survivability and growth of the all-test organisms over different time periods, with minimal LC50 values, indicating no toxic to tested organisms. However, increased levels of total dissolved solids and electrical conductivity were observed as extract concentrations increased but considered to be safe below 5 mg kg, as compared to control. Moreover, Fe, Cr, Ni, Cu and Zn (43.60, 0.10, 0.44, 0.07, 0.27 and 0.13 mg kg of dry weight, respectively) in UI were found to be low levels compared to previous studies, in addition, Cd and As remained not detected. No significant health risk (HQ < 1) and target carcinogenic risk were found. Therefore, UI could be utilized as functional foods or nutraceuticals for health-conscious consumers of Bangladesh without having potential risks.
肠浒苔是一种广泛可得的可食用海藻，在孟加拉国具有作为功能性食品引入的潜力。然而，此前尚未通过生物毒性测定评估这种海藻的潜在健康危害及其与重金属含量的关系。出于这些目的，使用多种生物，如普通小球藻、卤虫、大型溞和生菜，评估了从蒙哈利海滩浮筏养殖中采集的肠浒苔的毒性作用。与此影响相关，随后分析了重金属浓度（铁、铬、镍、铜、锌、铅、镉和砷）及其潜在健康危害。结果表明，肠浒苔水提取物在不同时间段对所有受试生物的生存能力和生长具有积极影响，半数致死浓度值极低，表明对受试生物无毒。然而，随着提取物浓度的增加，总溶解固体和电导率水平有所上升，但与对照相比，在5毫克/千克以下被认为是安全的。此外，与先前的研究相比，肠浒苔中的铁、铬、镍、铜和锌（干重分别为43.60、0.10、0.44、0.07、0.27和0.13毫克/千克）含量较低，此外，未检测到镉和砷。未发现显著的健康风险（危害商数＜1）和目标致癌风险。因此，肠浒苔可作为功能性食品或营养保健品供孟加拉国注重健康的消费者使用，而不存在潜在风险。
