Geochemical Distribution of Heavy Metals in Peat Soil Profile and Estimation of Water Table Patterns in Peatland at Klias Peninsular, Sabah.

Abstract The geochemical distribution of heavy metals in peat soil profile and estimation water table patterns peatland oil palm plantation were carried out the Klias Peninsular West Coast Sabah. geological setting mainly consists Crocker Formation Quaternary Alluvium which composed soil. from 10 sites collected for analysis. geophysical surveys performed to measure table, influenced concentration trace metals. analysis at 0-6m depth shows an acidic pH value (3.0-4.0), moisture content (90%-1000%) organic matter (30-99) %. texture varies top silty clay bottom profile. result that element Fe has highest (37.54-2049.18)mg/kg followed by Zn(5.13-270.06)mg/kg, Mn(0.1-253.56)mg/kg, Pb(0.71-157.46)mg/kg, Cr(0.05-152.62)mg/kg, Ni(0.1-64.48) mg/kg Cu(1.81-61.39)mg/kg. ranging (0.25m-0.3m) induced oxidation Fe. 2+ tends absorb other elements such as Zn Mn. Whereas, (5-5.5) enhanced absorption Pb, Cr, Ni Cu
