Tin is a relatively scarce element with an abundance in the earth’s crust of about 2 parts per million (ppm), compared with 94 ppm for zinc, 63 ppm for copper, and 12 ppm for lead. Most of the world’s tin is produced from placer deposits; at least one-half comes from Southeast Asia.
Is tin toxic for cooking?
Tin is non-reactive and rarely toxic to humans, so it is a relatively safe coating for copper pans. Also of note, however: tin combined with carbon (organotins) are used in making plastics, food packages, pesticides, paints, and wood preservatives, and these combinations are highly toxic.
