Abstract

Foundry "A .. i~ an airborne dust sample that was taken in a sand foundry. The quartz content is observed to vary from 12 to 18~~ in the 0.5to 2-micron size range and is usually referred to as a typical foundry dust sample (Hatch and Make, 1936; Williams. 1945 ). Analysis by calculation of the particles less than 5 mi.:-rons as a single dust sample would result in approximately 25°~ quartz. Foundry "N'' i~ an airborne dust sample that was taken from a nonferrous foundry. In this case, the quartz content varies from a low of sa:-~ for the coarsest particles to a high of 35o;;; for the 0.510 !-micron size particles. Analysis of the less than 5-micron size fraction as a single sample would by the same reasoning result in an analysis of approximately 1 0~~
