The present invention relates to a method for fabrication of blue-fluorescent and non-toxic nanodiamonds from atmospheric particulate matters including total solid suspended particulate matter (TSPM) and particulate matter with size less than 10μ (PM.sub.10). Mostly, the present invention provides an efficient mitigation process for particulate pollutant by conversion of these pollutants (PM and TSPM) into non-toxic high-value product such as nanodiamond by using the ultrasonic-assisted chemical oxidation method. This method is environmental friendly, simple, and biocompatible for the production of nanodiamonds from such atmospheric particulate matter.
