# Logos The CRACMM logo reflects the three air quality endpoints for which CRACMM was designed: particulate matter, oxidants, and hazardous and toxic air pollutants. On the left is an isoprene epoxydiol, a major precursor to particulate matter. In the center is ozone a photochemical oxidant and regulated criteria air pollutant. On the right is formaldehyde, a carcinogen and driver of cancer risk from ambient exposure to air toxics. ![CRACMM_1](CRACMM_1.png) Download this image as a [PDF](CRACMM_1.pdf) or as a [PNG](CRACMM_1.png) ![CRACMM_2](CRACMM_2.png) Download this image as a [PDF](CRACMM_2.pdf) or as a [PNG](CRACMM_2.png) ![CRACMM_3](CRACMM_3.png) Download this image as a [PDF](CRACMM_3.pdf) or as a [PNG](CRACMM_3.png) ![CRACMM_4](CRACMM_4.png) Download this image as a [PDF](CRACMM_4.pdf) or as a [PNG](CRACMM_4.png) ![CRACMM_5_BW](CRACMM_5_BW.png) Download this image as a [PDF](CRACMM_5_BW.pdf) or as a [PNG](CRACMM_5_BW.png)
