Metal and metalloid bioaccumulation in dried red seaweed Hypnea musciformis and health risk assessment for consumers
Original language description
This study measured 22 metal and metalloid concentrations in Hypnea musciformis from the Bakkhali River estuary and Saint Martin's Island, Bangladesh and determined their potential impact on consumption. Student t tests showed a significant variation in metal concentrations between the two sampling sites (p < 0.05). Mean concentrations of Co (2.49 & PLUSMN; 0.05 mg/kg), Fe (793.29 & PLUSMN; 11.76 mg/kg), Mn (368.72 & PLUSMN; 4.87 mg/kg), Pb (3.82 & PLUSMN; 0.02 mg/kg), V (11.23 & PLUSMN; 0.20 mg/kg) and Zn (16.60 & PLUSMN; 0.28 mg/kg) were higher in samples collected from the Bakkhali River estuary compared to Saint Martin's Island, while mean concentrations of Ca (484.18 & PLUSMN; 4.68 mg/ kg), Cd (2.44 & PLUSMN; 0.03 mg/kg), Mg (2112.70 & PLUSMN; 17.80 mg/kg), Mo (1.57 & PLUSMN; 0.06 mg/kg), Sr (2377.57 & PLUSMN; 29.98 mg/ kg), and Ti (258.27 & PLUSMN; 4.62 mg/kg) were higher in samples collected from Saint Martin's Island. Eight heavy metals (Pb, Cd, Zn, Cu, Ni, Mn, Cr, Fe) were used to assess potential health risks for adults, but no potential health risk was detected (HQ value>1). This study reveals positive Se-HBV for H. musciformis collected from both sampling sites, indicating no potential risks involved with Hg toxicity.
