1. An airborne particle collection system comprising:
a portable monitoring device comprising:
a housing comprising an air-intake slot, the air-intake slot having a length and a width, wherein the length is greater than the width;
a first illumination source that emits an approximately monochromatic emission spectra that corresponds to an absorption spectrum of a particle of interest;
a second illumination source that emits white light;
a third illumination source that emits ultraviolet (UV) light;
a battery to supply power to the first, second, and third illumination sources;
a network interface controller; and
a camera sensor;
a removable collection cartridge comprising:
a cartridge housing, separate from the housing of the monitoring device; and
a collection media contained within the cartridge housing; and
an analysis server, remote from the portable monitoring device, wherein images of particles collected onto the collection media and captured by the camera sensor are transmitted to the analysis server for analysis.
