Tin Toxicity

A comprehensive review of inorganic tin shows it to be innocuous to human health. Stannous chloride is a food additive used in canned soda pop up to 12.5 PPM, canned asparagus up to 20 PPM, and canned tuna up to 1500 PPM. We generally apply 0.2 PPM or less of stannous chloride in our drinking water treatment programs. The USDA placed stannous chloride in the "Generally Regarded As Safe" (GRAS) category at those dosages.

From a wastewater perspective, tin is also innocuous; there is no nutritive value added to the wastewater stream from stannous chloride, unlike phosphates. Also, unlike zinc, tin is a non-regulated metal. This could be an important factor in determining the fate of sludge.

Tin has also been used as a container for food storage for many decades. In Germany, there is a patented process by which copper pipe is tin-coated to reduce elevated copper levels.

For more information, see the World Health Organization's 2005 report TIN AND INORGANIC TIN COMPOUNDS, and the 2004 report INORGANIC TIN IN DRINKING-WATER.
