Abstract

This study was carried out to determine heavy metal content and physico-chemical properties of soil’s influencing heavy metal accumulation in some series surrounding the Chini Lakes. A total of 15 topsoil sample were collected randomly from 6 stations. The physical properties that were analyzed include particle size distribution and soil organic matter. Meanwhile, the chemical characteristics determined were pH, electrical conductivity and cation exchange capacity. It was found that heavy metal content of Cd, Cr, Cu, Co, Pb, Zn and Mn were low whereas Fe content was high. The textures of soil studied were clay, loamy sand, sandy loam, clay loam and silty clay loam. The mean of organic matter ranged from 2.68 to 11.46%. The soil pH showed that the soil studied was acidic with values ranged between 3.36 to 3.72. The range of electrical conductivity mean was between 2150 µScm^-1   to 2403 µScm^-1. Cation exchange capacity mean ranged from 2.85 hingga 8.59 cmol_c/kg. Correlation analysis showed that there were positive and negative significant correlations between soils parameters heavy metal concentration.  Analysis  of  variance  (ANOVA)  showed  that  there  were  significant  differences  in  organic matter percentage, pH, cation exchange capacity and heavy metals except cadmium between sampling station.
