Description
Summary:Sister chromatid exchanges (SCE) in Vicia faba root tips were used to examine well water containing high levels of arsenic. The increased amount of arsenic was contained in well water from different towns of Zimapan, Hidalgo, Mexico. Treatments of 3 h were applied followed by the differential staining technique of Tempelaar et al. (Mutation Res. 103 (1982) 321–326). Concentrations of arsenic from 0.267 up to 1.070 mg/l were determined by colorimetry in the polluted samples used for this study. These values were above the permissible limit of 0.05 mg/l in drinking water. In all cases, except one in which the As concentration was 0.021, the arsenic-contaminated water produced significant increases of SCE compared with the control ( p
