Light microscopy examination of representative lung sections from sham (a-b) and exposed rats 24 hours after 250 μg (c-d), 500 μg (e-f), or 1000 μg (g-j) PM2.5-AB instillation, respectively. Light microscopy examination at higher magnification revealed PM-laden macrophages after instillation of 1000 μg PM2.5 Figures 3i and j show two different microscopic fields.Back to article page
