dc.description.abstract | Objectives Particulate matter (PM) exposure has become one of the most serious problems. The aim of the present study was to evaluate the hair cell damage and possible developmental toxicity caused by PM2.5 exposure using a zebrafish model. Methods Zebrafish embryos were exposed to various concentrations of PM2.5. Developmental toxicity was evaluated based on general morphology score (GMS) system and Panzica-Kelly score, and by measurement of body length and heart rate. To evaluate hair cell damage, the average number of total hair cells within four neuromasts exposed to various concentrations of PM2.5 was compared with that of the control group. Results Morphological abnormalities evaluated by the GMS system and Panzica-Kelly score were rare and body length tended to be shorter in the PM2.5-exposed groups. Heart rate decreased significantly in the PM2.5-exposed group. Additionally, significant hair cell damage was observed after PM2.5 exposure. It was dose-dependent and more severe after a longer period exposure (10 dpf). Conclusions In zebrafish embryos, exposure of PM2.5 in the early stages of life decreased heart rate and caused significant hair cell damage in a dose-dependent manner. | - |
