From: Variation in Tree Species Ability to Capture and Retain Airborne Fine Particulate Matter (PM2.5)
Differences in foliar PM2.5 accumulation between different leaf shapes (a) and venation patterns (b) pooled from all species measured. Bars are means ± SE. Different letters above the error bars indicated significant differences between leaf shapes (Bonferroni test, α = 0.05).
