Overview of study design and nasal lavage sampling. The subjects were exposed for 5.5 h to either filtered air or welding fumes at 1 mg/m3 (PM2.5). Nasal lavage fluids were collected on four occasions, twice prior to exposure and twice after. The first sample was a washout (NL 0, not analyzed), the second was the baseline sample (NL 1), which was taken 30 min after the wash out, the third sample was collected immediately at the end of exposure (NL 2), and the fourth sample was taken 18–20 h after the end of the exposure (NL 3). Two subjects had missing samples and were therefore excluded in the analysis of the pooled samples
