Fig. 2From: Single inhalation exposure to polyamide micro and nanoplastic particles impairs vascular dilation without generating pulmonary inflammation in virgin female Sprague Dawley ratsReal-time size characterization of the whole-body inhalation facility shows the presence of nanoscale particles (A), and microparticles (B). Time-integrated characterization of the overall particle size fractionation during exposure was quantified using a Harvard Compact Cascade Impactor (C). Data are presented as mean ± SEM.Back to article page
