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.
采用原子吸收分光光度法测定了焊接马口铁罐装果蔬中铅、铬、锡、铁和镉的含量。将所测得的含量与焊接马口铁罐装食品和新鲜食品中的含量进行了比较。结果表明，焊接罐食品中的铅含量远低于焊接罐同类食品中的铅含量。未涂漆焊接罐中的食品比涂漆焊接罐中的食品含有更多的铅、铬和锡。焊接罐中罐装果蔬的镉和铁含量与相应新鲜食品中的含量相似。
