Abstract
The present study investigated the bioaccumulation of metals in raw, heat treated -and sterilized Rapa whelk, and evaluated consumer risks for human. All metals, except Mn, were lower than permissible FAO standards. A remarkable amount of metal was released into the cooking juice (Al, Cr, Cu, Fe, Hg, Pb, Sb, Se, Zn) after heat treatment, and hypochlorite solution (Al, As, Cu, Hg, Mn, Pb, Se, Zn). After sterilization, the levels for As, Mo, Cd, Sb, Cr, Zn, Se, Cu, and Hg in Rapa whelk were reduced by 47.4%, 40.1%, 24.9%, 20.3%, 17.5%, 4.5%, 3.6%, 0.93%, and 0.68%, respectively. Metals in Rapa whelk exposed to hypochlorite immersion were below permissible upper limits. Target hazard quotients for non-carcinogenic risks of consuming sterilized Rapa whelk were below “1” (THQ
