An analytic method for the determination of phenoxy acid herbicides and 2,4-D esters in soil samples by GC-FID is described. The esterification reaction with MeOH and H(2)SO(4) as catalyst has been used, optimizing experimental variables by the 'Simplex method'. The recoveries in soil samples were between 76 and 97% with relative S.D.s between 4 and 7% (n=4) at level of concentration of 5 and 10 mug ml(-1) for phenoxy acids and 2,4-D esters, respectively.
