All of them from the island of Itaparica, Bahia. Values ​​equivalent to the percentage of organic matter and calcium carbonate and particle size analysis are also presented in the samples investigated. Trace and major elements were determined by ICP OES and higher concentrations (µg g -1 ) were found mainly in the Misericórdia (Mn: 36.35 ± 1.14; Ba: 11.01 ± 1.71; V: 10.55 ± 1.81; Mo: 10.77 ±1.82) . Cacha Pregos (Mn: 26.75 ± 2.51; Ba: 9.77 ± 1.42; Cu: 20.38 ± 6.55) and Jeribatuba (Ba: 9.88 ±0.46).   High concentrations of Mn in Baiacu and Ponta Grossa were also presented. Statistical analysis expressed by Pearson Correlation Matrix and Principal Component Analysis (PCA) established relationships between variables and samples studied, corroborating metal concentrations found in the samples of Misericórdia, Cacha Pregos and Jeribatuba.
