Cytotoxicity of asbestos-cement in V79-cells. Cells were treated with various doses (1 μg/cm2, 5 μg/cm2, 10 μg/cm2, 20 μg/cm2) of asbestos-cement and chrysotile for 24 hrs (A), 48 hrs (B) and 72 hrs (C). The percentage of decreased cell viability is shown in relation to the untreated control. The cytotoxicity was determined by trypan blue-staining. The experiments were repeated twice. SD < 1%
