Fig. 2
Mean (± SD) of the log transformed area (µm2) of manufactured low-density polyethylene microspheres (Fluorescent Blue Polyethylene Microspheres 1.13 g/cc 90–106 μm, Cospheric, CA, USA) compared to microspheres ingested, by adult Gryllus pennsylvanicus and recovered from the digestive tract following 3-days of exposure to contaminated diet. The horizontal line represents the 100 μm filter pore size, the filter size used to recover microplastics from field captured crickets. Ingested microspheres were significantly smaller than manufactured particles (c2 = 19.3, d.f.=1, p < 0.001).
