Haemolytic potential of DE samples. Percent haemolysis relative to an untreated control, of sheep red blood cells post-exposure to 1 mg/ml of unprocessed (white), calcined (light grey) and flux-calcined (dark grey) DE and positive (DQ12) and negative (TiO2) standards (black). Error bars represent standard error (n = 3), *** p = <0.001 difference from untreated control
