The present study aimed to assess the levels of heavy metals and metalloids present in six seaweeds and their potential impact on consumption. The highest concentration of 11 metals, i.e., Be (0.47 mg/kg), Co (4.34 mg/kg), Cr (23.46 mg/kg), Cu (11.96 mg/kg), Fe (2290.26 mg/kg), Li (11.55 mg/kg), Ni (13.75 mg/kg), Pb (6.67 mg/kg), Ti (736.62 mg/kg), Tl (0.14 mg/kg), and V (33.09 mg/kg) were observed in Enteromorpha intestinalis (green seaweeds). Besides, the highest concentration of Ca (1071.09 mg/kg), Cd (5.81 mg/kg), Mn (1003.41 mg/kg), Sr (2838.86 mg/kg), and Zn (41.95 mg/kg) were found in Padina tetrastromatica (brown seaweeds). Eight metals (Pb, Cd, Zn, Cu, Ni, Mn, Cr, Fe) have been used to assess the potential health risk for adults, but no potential health risk was detected (HQ value > 1). The HI value of E. intestinalis and P. tetrastromatica were >1, implying that these two seaweeds are not safe for human consumption as there is a carcinogenic health risk for adults.
本研究旨在评估 6 种海藻中重金属和类金属的含量及其对食用的潜在影响。11 种金属的浓度最高，即 Be（0.47mg/kg）、Co（4.34mg/kg）、Cr（23.46mg/kg）、Cu（11.96mg/kg）、Fe（2290.26mg/kg）、Li（11.55mg/kg）、Ni（13.75mg/kg）、Pb（6.67mg/kg）、Ti（736.62mg/kg）、Tl（0.14mg/kg）和 V（33.09mg/kg），均存在于肠浒苔（绿藻）中。此外，在长松萝（褐藻）中发现了最高浓度的 Ca（1071.09mg/kg）、Cd（5.81mg/kg）、Mn（1003.41mg/kg）、Sr（2838.86mg/kg）和 Zn（41.95mg/kg）。用 8 种金属（Pb、Cd、Zn、Cu、Ni、Mn、Cr、Fe）评估成人的潜在健康风险，但未检测到潜在健康风险（HQ 值>1）。肠浒苔和长松萝的 HI 值均大于 1，这意味着这两种海藻不适合人类食用，因为它们对成年人有致癌的健康风险。
