  • Title: Lead, chromium, tin, iron and cadmium in foods in welded cans.
    Author: Jorhem L, Slorach S.
    Journal: Food Addit Contam; 1987; 4(3):309-16. PubMed ID: 3653455.
    Abstract:
    The levels of lead, chromium, tin, iron and cadmium in fruit and vegetables in welded tinplate cans were determined by atomic absorption spectrophotometry. The levels found were compared with those in foods in soldered tinplate cans and fresh foods. The results show that the lead levels in foods in welded cans were much lower than those in similar foods in soldered cans. Foods in unlacquered welded cans contain much more lead, chromium and tin than foods in lacquered welded cans. The cadmium and iron levels in canned fruit and vegetables in welded cans were similar to those found in the corresponding fresh foods.
