TFA Concentration in Leaf Samples

What the figure shows
Line chart, 2011 to 2020, of TFA concentration in leaf samples in micrograms per kilogram dry weight. Pyramidal poplar falls from about 470 in 2011 to about 380 in 2013, then rises to about 1,030 in 2020. Rotbuche (common beech) rises from about 150 in 2012 to about 320 in 2019. A third line on a second axis, modelled TFA entry from HFO-1234yf emissions in tonnes, rises from near zero to about 220 in 2020.
