Alpha diversity distribution (Observed number of species and Shannon’s diversity index) for subway station (left panels) and outdoor (right panels) samples collected with SASS and Bobcat air samplers. Sample pairs, i.e., samples collected side-by-side with both sampler types, are color codedBack to article page
