Membranolytic activity (percent hemolysis) of A pristine engineered stone (ES1-5), natural stone (NS), and positive reference quartz (Min-U-Sil 5) dusts and B-H the same samples after thermal treatment. Increasing surface area doses (0, 6.25, 12.5, 25, 50, 100, and 200 cm2/ml) of ES, NS, and reference quartz dusts were incubated for 30 min with purified sheep RBCs. Values reflect the fraction of the total released hemoglobin content and are reported as mean ± standard error of the mean of at least three independent experiments. Two-way ANOVA and Šidák correction were applied to compare pristine vs. treated dust.
