AIR SAMPLING AMD ANALYSIS'
t----------------------rjvascollected on Tenax*-GC tubes. Air was drawn through the tuoes b^ Du Font Model P-200 pumps calibrated at about 60 raL/min. Tienax^-GC tubes were thermally desorbed at 200C using an EnvirochemiUnacon Series 010 Thermal Derorber at
Seaford. The carrier gas was nitrogen. Samples were analyzed on
a Hewlett-Packard Series i840 gas chroma tog^-aph equipped with a flame ionization detector and a 3.28' x 1/8" stainless steel column packed with 15% Igepal C0880 and 51k potassium hydroxide on Chromosorb W. Two samples were analyzed at Jackson Laboratory
using ion selective chromaltography to determine total fluoride.
Samples were collecteld at the following locations around
spinning machine 370T:
