TOXICOLOGICAL PROFILE FOR ZINC

Zinc is widely distributed in nature, constituting 20–200 ppm (by weight) of the Earth's crust (Goodwin. 1998), but it is not found as elemental zinc in nature (Lloyd and Showak 1984). The procedure used to mine zinc varies with the composition of the ore. The mineral sphalerite (ZnS) provides ca. 90% of the zinc produced.
