Fig. 2

Degradation of pelargonic acid-D17 in 4 agricultural topsoils (top row) and 3 soils from railway tracks (bottom row). Fitted single first order (SFO) decline curves are plotted as solid lines, bi-phasic decline (hockey stick) as dashed lines. Data from experiments with starting concentration 15 mg/kg are shown in black, those with 5 mg/kg in blue
