Figure 4

Cytotoxicity of BEAS-2B exposed to ADE/non-ADE PM₁₀ organic extracts from the urban site. A value <80% was considered cytotoxic. Triton-X 25 µg/mL was used as positive control (+CNT). Bars represent mean cell viability ± SEM, of three independent experiments. Negative controls are medium and the carrier dimethylsulfoxide (DMSO) at 0.1%. Individual asterisks represent statistical significance compared to DMSO.
