Effect of indoor and outdoor dusts on AGS, A549 and L929 cell viability. A) The cells were cultured in 10% FBS medium and treated with outdoor and indoor dusts for 48 and 72 h and cell viability was measured by MTT assay. B|) The indoor and outdoor dust samples were categorized according to traffic states (LT: low traffic, MT: medium traffic and HT: high traffic) and cell viability was measured after 72 h cell treatment with these. The percent of viable cells (%) was calculated in comparison to untreated cells. The number of cells in the control was taken as 100%. Values were expressed as mean ± SD: of three independent experiments, each performed in triplicate (∗P < 0.05 and ∗∗P < 0.01; #P < 0.05 and ##P < 0.01; $ P < 0.05 and $$ P < 0.01).
