Relative percentage of endothelial cell abluminal membrane contacts (15 nm or less) with subtending cells or substrate elements. Particulate air pollution (particles smaller than 10 μm in diameter; PM₁₀)-exposed rabbits (n=5) have significantly less contact with dense extracellular matrix, and significantly more contact with fragmented extracellular matrix, macrophage-derived foam cells and space than control rabbits (n=7). *P<0.0001; **P<0.005
