  abstract = {{T}he aim of this work is to identify the elements present in vegetables and soils using {PIXE} (particle induced {X}-rays emission) and {C}f-252-{PDMS} ({C}f-252 plasma desorption mass spectrometry) techniques in order to estimate the possible influence of soil and agricultural techniques in the metal absorption by the vegetables. {I}n this work, metal concentrations were evaluated in soil and vegetable samples from several regions, where different agricultural techniques were employed. {S}i, {Z}r, {C}e, {T}h, {S}c and {P}b identified in the soil samples were not biologically available. {G}a, {G}e, {A}s and {B}r identified in the tubercles indicate that spray pesticide used on the vegetable leaves was absorbed by them. {T}h-232 and {U}-238 present in the soil were not absorbed by the vegetables. {T}he airborne particles from anthropogenic sources (as {CF}n, {VC}n) were absorbed by the vegetables. {C}ompounds from mineral sources present in soil as {V}+, {VCO}3, {HPO}4, {C}r+, {C}r{OH}+, {M}n+, {F}e{H}+, {F}e({OH})(n) and in the bioorganic compounds as {N}+, {C}a({CN})(n)(+) and {C}n{H}+ were identified in vegetables. {T}he metal absorption by the vegetables is not dependent of the metal concentration in soil. {D}ifferent tubercles cultivated in the same soil show similar metal absorption. {T}he exogenous contributions such as the elements present in water irrigation, pesticides, fertilizers and airborne particles deposited on leaves can be absorbed by vegetables. {T}he absorption by the roots depends on the chemical compound of the elements. {T}he use of pesticide sprays and air pollution can cause more contamination in the vegetables than in soil. {T}he use of this methodology allows the identification of possible sources of metals in soils and in vegetables and the metal speciation.
