Fig. 1From: Particle characterization and toxicity in C57BL/6 mice following instillation of five different diesel exhaust particles designed to differ in physicochemical propertiesTEM images of DEP9.7 (a), DEP13 (b), and DEP17 (c), HVO13 (d), RME13 (e) and CB (f). The morphology of the particles generated with 13 and 17% O2 conditions (b, c, d, and e) are similar, while the soot agglomerates generated with 9.7% O2 (a) have less defined primary particles and appear more aggregated compared to the other samplesBack to article page
