This report is an addendum to report no 725201005, in which human toxicological guideline values and daily intakes for man are derived based on of a search of the toxicological literature in order to derive C-values for soil. Maximum tolerable risk levels for the total intake of genotoxic carcinogens and toxicologically tolerable daily intakes for threshold compounds have been determined for the following compounds or groups of chemically related compounds: sulfides, anthracene, naphthalene, PAH (total), chlorinated PAH, oxidized PAH, mineral oil, and tetrahydrothiophene. In addition, the maximum tolerable risk level for benzene has been revised.
