A total of 14 substances, among them the carcinogenic compounds resorcinol diglycidyl ether, furane, 2-nitropropane, perfluorooctane acid, and their inorganic salts, tetranitromethane, 2,4-Toluylenediamine, 1,2,3-trichloropropane, vinylcyclohexene, and an N-nitrosamines were newly labelled with the warning "H", which means that absorption through the skin together with inhalation may significantly contribute to their toxicity at the workplace. This warning label was checked and confirmed for propyleneimine.
The section BAT values, biological guideline values and exposure equivalents for carcinogens includes seven changes and new entries. Exposure equivalents for carcinogenic working substances have been newly listed for 1,3-butadiene, cyclohexanone, and 1,4-dichlorobenzene, a reduced BAT value for mercury, and BLW for 4-aminobiphenyl, lead (EKA). No BAT values were derived for n-heptane, methyl-tert-butylether, and molybdenum.
The Senate Commission produced detailed scientific justifications for each new entry and change in the 2005 MAK and BAT value list. The above may be requested from the DFG's Senate Commission on the Investigation of Health Hazards of Chemical Compounds in the Work Area, Hohenbachernstrae 15-17, 85350 Freising-Weihenstephan, phone: 49-0-8161-715601, fax: 49-0-8161-715618, e-mail: heidrun.greim@lrz.tum.de. Scientific comments and new data are requested to be submitted by the end of the year. After the above have been examined or considered, the documentation will be published by Wiley-VCH, Weinheim, Germany. Since early 2005, they have also been available online. As in every year, the examination and new entry of MAK values and classification of numerous substances is announced in the Yellow Pages of the MAK and BAT value list.
