In this work, the degradation of fungicide tolclofos-methyl (TM) by zerovalent metals (ZVMs) was first investigated prior to investigation of the effect of ferric salts during zerovalent iron treatment to better understand the feasibility of abiotic degradation mediated by ZVMs. Unannealed zerovalent iron (uZVI), annealed zerovalent iron (aZVI) and zerovalent zinc (ZVZn) were used as ZVMs sources. uZVI was found to be the most effective catalyst for degrading TM in aqueous solution. The TM degradation rate depends not only on the amount and sizes of uZVI used but also on the initial concentration of fungicide itself. By testing various kinds of salt, it was found that ferric sulfate and ferric chloride showed better results for degrading TM by uZVI in aqueous solution. The order of effectiveness of salts is $FeCl_3$>$Fe_2(SO_4)_3$>$FeSO_4$>$Al_2(SO_4)_3$.
