Correlation analysis between CXCL8 responses in HBEC3-KT cells and the content of organic carbon (OC) from coarse, fine and ultrafine PM sampled in road tunnels. The CXCL8 release at an exposure concentration of 100 µg/mL (10.4 µg/cm2) (n = 5) was compared to the levels of OC in the PM samples. The correlation was determined using Pearson’s correlation coefficient, which is presented in each panel. A OC at 310 °C; B OC at 475 °C; C OC at 615 °C; D OC at 870 °C; E OC at temperatures from 310 to 870 °C
