Figure 2. Mineralisation of 14C–phenanthrene in fresh artificially spiked soils amended with (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 concentrations of 50 µg kg-1 (●), 100 µg kg-1 (○), 200 µg kg-1 (■) and unamended soil (□). Error bars, where visible, represent standard error of mean (n = 3)
