INFLUENCE OF SOME PHYSICO-CHEMICAL PARAMETERS OF SOIL ON HEAVY METAL ACCUMULATION

Ibrahim Yusuf, Kabiru Mohammed and Galadima Muhammad Abubakar

ABSTRACT

Soil contaminated with heavy metals is poor in nutrients and contribute to sub-optimal plant biomass accumulation. Soil, whether in urban or rural areas, represent a major sink for metals released into the environment from a variety of activities. Some of the metals will persist because of their immobile nature; others will be more mobile migrating to either ground water or plants.  Samples were collected using stratified random sampling method. Each sampling area was divided into ten smaller units and from each unit; ten (10) samples were collected randomly at an average depth of 10-15 cm, the sample were mixed and homogenized. The following metals were analysed Cu, Cr, Cd, Pd, Co, Ni and Zn the result obtained showed that correlation is significant at 5% level.
