Additional information

Benzene has a Henry's Law Constant of 557 yo 562 Pa.m3/mol based on experimental values reported by Lide 2008 and in EpiSuite, respectively. No information on the methods used is available for the Lide 2008 value but this information is taken from a reliable peer reviewed handbook and is considered reliable and suitable for use for this endpoint. QSAR calculated values also support the experimental database values.
