Estimated Henry's Law Constant

This page provides a description and a link to a "Estimated Henry's Law Constant" modeling tool that can be used for modeling exposure levels or information needed in exposure assessment.

Short Description

Henry's Law Constants characterize the equilibrium distribution of dilute concentrations of volatile, soluble chemicals between gas and liquid. For this calculator, the liquid is water. Temperature-dependence is calculated by two methods: one developed by the EPA Office of Solid Waste and Emergency Response and the other published in the journal Ground Water and written by John Washington in 1996.
