英文摘要	Formic acid is the major contributor to acid rain in some regions but its sources are not fully understood We investigated the aqueous phase reactions of HCHO (aq) and OH radicals at enlarged rainwater pH values (2 49-5 89) in Guiyang China from May 2006 to April 2007 Our results show that there were no significant correlation between the [HCOOH](t)/[HCHO] (aq) and the rainwater pH The ratio did not appear to vary consist ently as a function of rainwater pH as predicted by theoretical model In addition we saw no clear evidence that oxidation of HCHO (aq) would produce significant HCOOH (aq) which indicates this reaction may be only a minor contribution to the budget of HCOOH (g) in atmosphere Further investigation is strongly suggested to be carried out in field cloud water fog water or rainwater because the ratios would be diverged from equilibrium value as a result of other chemical or physical processes; Formic acid is the major contributor to acid rain in some regions but its sources are not fully understood We investigated the aqueous phase reactions of HCHO (aq) and OH radicals at enlarged rainwater pH values (2 49-5 89) in Guiyang China from May 2006 to April 2007 Our results show that there were no significant correlation between the [HCOOH](t)/[HCHO] (aq) and the rainwater pH The ratio did not appear to vary consist ently as a function of rainwater pH as predicted by theoretical model In addition we saw no clear evidence that oxidation of HCHO (aq) would produce significant HCOOH (aq) which indicates this reaction may be only a minor contribution to the budget of HCOOH (g) in atmosphere Further investigation is strongly suggested to be carried out in field cloud water fog water or rainwater because the ratios would be diverged from equilibrium value as a result of other chemical or physical processes
