- To quote "McGraw-Hill Encylopedia of Science & Technology," 5th ed, p734:
-
- "Tin metal and the simple inorganic salts of tin are nontoxic. Tests have
- shown that concentrations of tin well above allowed limits in canned goods can
- be consumed without obvious adverse effects on the human system. Some forms of
- organotin compounds, on the other hand, are toxic."
-
- There are compounds of tin with biocidal properties, but that is beside the
- point. Exposure to tin from soldering is not dangerous. I am not concerned
- about exposure to lead from soldering either.
