Relationships between atmospheric aerosol properties and oxidative capacity, and pro-inflammatory and oxidative markers. The number concentration of nanoparticles N${}_{8-20}$ (panels A, B), Condensation Sink of nanoparticles CS${}_{8-20}$ (panels C, D), insoluble Copper (Cu) mass concentration (panels E, F), and (G, H) total oxidative potential (DTT activity of PM${}_1$ samples) is presented against the fold change (f.c.) in gene expression for HMOX-1 (oxidative stress) and CXCL-8 (inflammation). Data points are indicated with standard deviation error bars. Linear regression lines are indicated with a 95% confidence interval (dashed ribbons), and relevant date of measurements (dd/m).
