I would like to ask on the desired number of leaves (given the diff. sizes) that will be collected to obtain sufficient amount of Particulate Matter?

12 March 2018 1 5K Report

I am interested on quantifying particulate matter deposition on leaves. However, I haven't read from my literature reviews on the exact number of leaves that will be collected for quantitative analysis of Particulate Matter. Thank you so much.

The age and roughness of the leaf surface influences accumulation of particles. In addition, the concentration on the leaf depends on the outdoor concentration and the recent meteorological conditions. Leaf PM in the PM2.5 fraction may differ among the species 15 fold. Therefore, this is situation and species specific.
