V. faba plants were grown in sand with 0-10% cement kiln dust (CKD) solution for 12 h after which cell division was studied in root tips. CKD decreased the mitotic index, which was inversely proportional to the CKD concentration, while frequency of abnormality during mitosis was directly proportional. Chromosome breakage, stickiness of chromosome, c-metaphase, chromosome extrusion, ring chromosomes, chromosome bridges, lagging chromosomes, c-anaphase, tripolar anaphase and multipolar anaphase were observed at metaphase and anaphase stages in treated cells. Chromosomal breakage and chromosome bridges were predominantly recorded at metaphase and anaphase, respectively. It was concluded that CKD may also act as a strong mutagen.
