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.

本研究旨在评估六种海藻中重金属和准金属的含量及其对消费的潜在影响。11种金属的最高浓度，即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) 和 V (33.09 mg/kg)浒苔（绿海藻）。此外，在Padina中发现最高浓度的Ca（1071.09 mg/kg）、Cd（5.81 mg/kg）、Mn（1003.41 mg/kg）、Sr（2838.86 mg/kg）和Zn（41.95 mg/kg）四层虫（棕色海藻）。八种金属（铅、镉、锌、铜、镍、锰、铬、铁）已被用于评估成人的潜在健康风险，但未检测到潜在的健康风险（HQ 值 > 1）。E.肠球菌和P. tetrastromatica的HI值> 1，这意味着这两种海藻对人类食用不安全，因为对成年人有致癌的健康风险。
