Laboratory measurements of Henry's law constants are reported for 51 chemicals, spanning a wide range of chemical structures and volatilities. A static headspace method (Equilibrium Partitioning in Closed Systems, referred to as EPICS) was used to measure Henry's Law Constant, with the standard-batch air-stripping method used as a check. An average precision of 5% was obtained for the EPICS runs, and the Henry's law constants agreed reasonably well(within 10%) with the batch air-stripping results and other reported experimental values. Measurements were conducted over a temperature range of 10-30 C, and the data were correlated with a temperature regression equation coupled with a temperature-dependent error term based on 95% confidence limits. The aqueous solubilities of the study compounds were also determined via the shake-flask method at temperatures of 10, 20, and 30/sup 0/C.pacts
