Figure 3. Mineralisation of 14C–phenanthrene in artificially spiked soils amended with 100 µg kg-1 (a) caffeic acid, (b) ferulic acid, (c) p-coumaric acid, (d) a mixture of hydroxycinnamic acids (caffeic acid, ferulic acid and p-coumaric acid at a 1:1:1 ratio) at 0 d (T1 [● = amended; ○ = unamended]), 16 d (T2 [ ▼= amended; = unamended]), 32 d (T3 [■ = amended; □ = unamended]) and 48 d (T4 [= amended; = unamended]) time points. Error bars, where visible, represent standard error of mean (n = 3)
