Lethal dose, lower limit

In the NCMS investigation [4], Sn-5Sb was included in the initial list. However, based on the down-selection criteria of toxicity and alloy properties assessment, it was not selected for a manufacturability assessment. It is stated in the report that Sb is highly toxic when inhaled or ingested and has the same Lethal Dose, Lower Limit (LDLo) as Cd. Therefore it was recommended to not consider Sb as a possible major constituent in Pb-free solders, although Sb has been present in solders utilized for military applications since the 1940s but only in small amounts, typically less than 0.5% [4j. 

The toxic symptoms, median lethal doses, carcinogenic potentials if any, flammability, flash points, lower and upper explosive limits, violent reactions, and section numbers in this book where these compounds are described at length are highlighted below in condensed form for 63 common solvents.
