Additional information

Toluene has a Henry's Law Constant of 485 Pa.m3/mol. The value has been calculated based on the physico-chemical properties of the substance and the equation set out in the Guidance R16 (ECHA 2012). The result is supported by data from the CRC Handbook (Lide 2008). No information on the methods used is available but this information is taken from a reliable peer reviewed handbook and is considered reliable and suitable for use for this endpoint.
