EC number: 270-659-9 | CAS number: 68475-76-3 A complex combination of finely divided inorganic particles separated from the exit gases formed during the manufacture of Portland cement. The flue dust consists of uncalcined raw materials along with partially calcined materials. Some Portland cement clinker is usually included. The major constituents of kiln dust are calcium carbonate, clays, shales, quartz and sulfate salts. The following materials may also be present:@Dolomite@Ca(OH)2@Feldspars@CaSO4@Fly ash@KCl@Iron oxides@K2CO3@CaF2@K2SO4@CaO@Na2SO4@Glasses of SiO2, Al.s@Portland cement chemicals [659

Description of key information
Additional information
From acute aquatic toxicity tests on algae and daphnia and from the long-term toxicity test on daphnia toxic effects were observed at high water accommodated fractions. Probably, these effects were caused by the high pH-value of the water fractions. As the EL10 value of the chronic test has been determined as 68.2 - much higher than 1 mg/L - and even the EL50 values from the acute toxicity tests have been determined above 10 mg/L, Flue dust is not deemed as an acute or chronic aquatic toxic hazard.
