Smoke Exposure Has Transient Pulmonary and Systemic Effects in Wildland Firefighters
Figure 3
Induced sputum and macrophage particle inclusion cell counts, at baseline and after 1–7 days after fire exposure. 200 macrophage cells were counted per slide and percentage of having zero, less than 20, or more than 20 particle inclusions. Solid bars represent cell counts for each category at baseline. Grey bars represent cell counts for each category after fire exposure. Inclusion negative macrophages significantly decreased 1–7 days after fire exposure (*). Low inclusion positive cells (<20/macrophage) significantly increased 1–7 days after fire exposure (*). There were no significant changes in inclusion high-positive cells (>20/macrophage).
