Figure 3From: In vitro determinants of asbestos fiber toxicity: effect on the relative toxicity of Libby amphibole in primary human airway epithelial cellsCytotoxicity of airway epithelial cells in response to exposure to the different amphibole samples. Percentage of lactate dehydrogenase (LDH) leakage into the supernatant following a 24 h exposure to the highest dose (26.4 μg/cm2) of amphibole particles. * = Significant difference between treatment and no-treatment control. Difference is deemed significant when p < 0.05.Back to article page
