Heavy metal pollution of the environment is a universal problem and the soil often forms a repository of these elements. The developmental activities especially industrialization and high input agriculture contribute to accumulation of heavy metals to toxic levels in the soils. An attempt has been made to estimate the accumulation of heavy metals like iron, zinc, copper, cadmium, lead, nickel and manganese in the soil of Koratty region in central Kerala which has a history of industrialization. The various fractions of these heavy metals namely, exchangeable, reducible, oxidizable and residual fractions were determined to reveal the fate of these metals in soil. The fractionation was done following the BCR process suggested by European Community Bureau of Reference. Iron seemed to be the easily mobilized element, while cadmium and copper were least mobile. The order of mobility in the exchangeable fractions was Fe>Mn>Pb>Ni>Zn>Cu=Cd. The degree of contamination, enrichment factor, and index of geoaccumulation revealed that cadmium, nickel and lead are pollutants in Koratty region of Kerala.
