Methanol (C[H.sub.3]OH, LC-MS/MS hypergrade) and formic acid (HCOOH
, LC-MS/MS hypergrade) were obtained from Wako Pure Chemical Industries, Ltd.
Solvents A and B were 0.1% TFA (v/v) in [H.sub.2]O and 0.08% HCOOH
in C[H.sub.3]CN, respectively.

One mg of substance was suspended in 1 mL of solvent A (2.5 %(v/v) MeCN, 0.5 %(v/v) HCOOH
in water), sonicated for 10 min and centrifuged at room temperature for 10 min at 5000 rpm.
CSO (250 g) and a mixture of 26.62 g formic acid (double bond-to-HCOOH ratio 1:0.5) and 1.90 g [H.sub.2]S[O.sub.4] catalyst (catalyst loading 3 wt% of HCOOH
+ [H.sub.2][O.sub.2]) were placed in a three-necked, round-bottomed flask and 40.14 g 30% aqueous [H.sub.2][O.sub.2] (double bond-to-[H.sub.2][O.sub.2] ratio 1:1.2) was added dropwise to the reaction mixture (maintained at ~10[degrees]C) at a flow rate of 4.5 ml [min.sup.-1].

Estos procesos estan determinado por la neutralizacion de compuestos acidos (C[O.sub.2], S[O.sub.2], [H.sub.2]S[O.sub.4], HN[O.sub.3] y HCOOH
), los cuales, al impactar el suelo liberan metales como el Al, Hg, Cd, Cr, por lo que la concentracion de estos se incrementa en el aire (Spumy, 1996).
