The SSV website has been updated and reformatted as follows:

• The website now provides technical justifications for standard and non-standard land uses, followed by standard input parameters (1% SOM sand and 6% SOM sandy loam) and non-standard input parameters (1% SOM sand and 6% SOM sandy loam). We hope that this new layout will provide subscribers with all the information required in a clear and logical format.

• Tox information sheets have been updated for chlorobenzene, cyanide, trichloroethene and chromium.

• The tox sheets for PAHs which were updated in the SSV lists in December 2009/January 2010 (benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(g,h,i)perylene, benzo(k)fluoranthene, chrysene, dibenzo(ah)anthracene, indeno(1,2,3-cd)pyrene and pyrene) are in the process of being updated and will be posted on the website shortly.
