    Traduction en anglais : Major chemical accident at Hoechst AG Frankfurt/Germany : I : Data of environmental pollution and redevelopment.

    A major industrial chemical accident occurred on 22 February 1993 at Hoechst AG Frankfurt/Germany.

    Due to a series of errors in operational procedures approximately 11.8 tons of a chemical mixture were emitted, partly resulting in heavy contamination of a nearby housing area.

    The chemical mixture consisted of about 26% anorganic and 74% organic substances, mostly chlorinated nitroarenes, the most important organic contaminant being o-nitroanisol (about 27% of the total amount).

    Maximum earth contamination in allotment gardens was up to 8 g o-nitroanisol/m2, in the housing area 547 mg/m2.

    Maximum air contamination was up to 18 mug o-nitroanisol/m3, declining quickly during redevelopment and staying constantly below 2 mug/m3 from 2 March 1993 onwards.
