As a part of this program, comparable samples of raw ingredients and canned product were obtained during the 1972 season from canning plants in several locations, to obtain an indication of the amount of lead naturally incorporated in the product as well as that contri buted by the container. Ingredient samples for grape and orange drink were collected ------------------------R------I--I-I--q---*------------------- m--L---~--- J-------------------------------- -J---- j-- -- ------- -- ^1 - --------------- ---------------------------i_j - --.*-1 earliest available point and again at the filler. The fruit juices and drinks were packed in 404 x 700 plain (P) bodied or enamel lined (E) tinplate containers and stored less than 2 weeks before analysis.

The juice was packed in 1969 and samples were selected from major producing areas in proportion to their fraction of the total national production. Each sample was a composite of six No. 303, or similar size cans, or three 400 x 700 cans. The containers were either tinplate (plain bodied or enamel lined) or glass. They were analyzed after 8 to 14 months of storage.

Individual lead values obtained by various analytical methods in 22 juices, 10 drinks and 4 nectars canned in various sizes of plain bodied (P) or enamel lined (E)` tinplate containers and stored for one to three years are reported in the table. Lead concentrations in the product range from a trace (T) i.e., less than 0.10 ppm to a maximum value of 1.84 ppm.
