The present invention relates to a microarray for confirming the exposure of particulate matter 2.5 (PM2.5) to less than 2.5 micrometer (㎛) and a method for confirming the microarray by using the microarray. More particularly, As a result of the exposure of the extract and the organic extract, one type of micro-overexpressing micro-type was selected, and the micro-type micro-RNA was used as a biomarker to monitor micro-dust below 2.5 micrometer, And a tool for identifying a toxic action mechanism caused by fine dust less than 2.5 micrometers
