THE ARSENIC, LEAD, TIN, COPPER, AND IRON CONTENT OF CANNED CLAMS, OYSTERS, CRABS, LOBSTERS, AND SHRIMPS

Abstract

A survey of the heavy metal content of canned shellfish and crustaceans sold on the Canadian market has been made. With the exception of one sample of clams having 5 p.p.m. of lead, one sample of lobster having 13 p.p.m. of lead and, one sample of lobster having 7 p.p.m. of arsenic, of the 120 samples analyzed the values found were not significantly above the limits established for the heavy metal content of foods.
