Paper Abstract

In Germany, many abandoned sites are situated where during the world wars explosives (nitroaromatic compounds, nitramines and nitrate esters) were produced. They contaminate upper soils and ground/drinking water. Nitro- and aminoaromatic compounds have not only a potential for methemoglobin formation but also a carcinogenic one. Since 1992, 35 compounds have been evaluated toxicologically by our institute. We used an evaluation pattern weighting not only positive/doubtful/negative test results, but also data gaps, and which results in a standardized evaluation number (EN). Four compounds received an EN on a reliable data basis and 11 on a provisional one. For the other 20 compounds, mainly nitroxylenes and some dinitrotoluenes, the data basis was missing almost completely. A subset of 11 structures was classified, either for precautionary aspects or positive in vivo data, as probable human carcinogens, whereas for 7 not only an EN, but also a tolerable body dose (TDI) could be proposed. EN based guide values between 0,10 (mu) g/L (precautionary value) and 10 (mu) g/L (sum value) were derived for drinking water. In soils, a precautionary guide value of 1 mg/kg (sum value: 5 mg/kg) seems protective for all exposure scenarios without plant transfer, whereas TDI-based values are much higher.
