title = "Cytotoxicity assessment of nanoparticles and polycyclic aromatic hydrocarbons exhausted from motorcycle",
abstract = "The cell cytotoxicity of nanoparticles (NPs) and particle-bound polycyclic aromatic hydrocarbons (p-PAHs) in emission of a four-stroke motorcycle (4-st/mc) was studied. Cell cytotoxicity was evaluated by detecting the cell viability rate (3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide, MTT assay) of carcinomic human airway alveolar epithelial cells (A549) and the content of cytokine (IL-8) in the mucus of A549 after exposing to NPs and p-PAHs. In experiment, as the speed accelerated (15 km/h and 30 km/h), the concentration of high molecular weight PAHs (HMW-PAHs) increased. According to the result of MTT assay, the cell viability rate of A549 exposed to the NPs exhausted from idle condition was lower than that from 15 km/h and 30 km/h speed. However, the cell viability rate of A549 stimulated by p-PAHs exhausted from the 30 km/h condition was 15.9%, which was lower than 31.4% (idle) and 20.2% (15 km/h). It means the p-PAHs might be the main factor to induce the death of cell in the high speed condition. Moreover, p-PAHs exhausted from the idle condition could cause more serious inflammation in the A549 cells than that from other speeds.",
