Fig. 2. Methyl halide fluxes from soil samples amended with different chemicals.
a Methyl bromide (CH3Br) and b methyl chloride (CH3Cl) fluxes from live and autoclaved soil samples under different treatments. (i) 20 ml of deionized water was added; (ii) 10 ml each of deionized water and 50 mM H2O2 was added; (iii) 10 ml each of deionized water and 50 mM CuSO4 was added; (iv) 10 ml each of 50 mM H2O2 and 50 mM CuSO4 at were added. The dots represent the average fluxes of two replicated incubations (n = 2) in each treatment and the upper and lower boundary of the bars represent the two individual fluxes. The inserted plots in (a) are the enlarged view of CH3Br fluxes from soils in the first two treatments.
