    “…In view of the widespread consumption of periwinkle in the Niger Delta, Nigeria, this study was designed to assess the concentration and potential human health hazards of heavy metals due to the consumption of this rich, inexpensive and readily available source of protein in Calabar, Nigeria. METHODS. Lead (Pb), cadmium (Cd), chromium (Cr) and nickel (Ni) content of edible tissues of periwinkles obtained from major markets in Calabar were determined using Shimadzu atomic absorption spectrophotometer (Model AA-6800, Japan) after wet digestion. …”
