Abstract

This research was carried out to assess the physicochemical properties of the soil and concentration of heavy metals (lead, copper, zinc and nitrate) in waste dumpsite Ihiagwa Imo State, Nigeria. In other to assess the physicochemical properties of the soil in the study area , soil samples were collected from three (3) points labeled Point 1, Point 2 and Point 3(Control point) with depth ranging from 0-15 (top soil), 15-30 (Sub-soil), and 30-45 (Bottom). The physicochemical parameters and heavy metal results shows that the pH ranges from 5.756(sub soil) to 6.009 (top soil) at Point 1, from 5.722(sub soil) to 5.976(top soil) at Point 2, from 5.137(sub soil) to 6.147(bottom) at Point 3. The electrical Conductivity ranged from 80.50µs/cm (top soil) to 162.9µs/cm (bottom) at point 1, from 52µs/cm (top soil) to 90.1µs/cm(sub soil) at point 2, from 58.4µs/cm(sub soil) to 95.9µs/cm (bottom) at point 3. The bulk density ranged from 1.396g/cm3(top soil) to 1.462g/cm3 (bottom) at point 1, from 1.375g/cm3 (top soil) to 1.459g/cm3 (bottom) at point 2, from 1.399g/cm3 (top soil) to 1.511 (bottom) at point 3. Copper (Cu) ranged from 0.148Mg/100g (top soil) to 0.928Mg/100g (bottom) at point 1, from 0.232Mg/100g (top soil) at point 2, from 0.092Mg/100g (bottom) to 0.489Mg/100g (top soil) at point 3. Zinc (Zn) ranged from 0.12Mg/100g (bottom) to 0.21Mg/100g (sub soil) at point 1, from 0.098Mg/100g (top/sub soil) to 0.217Mg/100g (bottom) at point 2, from 0.026Mg/100g (bottom) to 0.188Mg/100g ( top soil) at point 3. Lead (Pb) ranged from 0.138Mg/100g (top soil) to 1.026Mg/100g (bottom) at point 1, from 0.282Mg/100g (top soil) to 0.547Mg/100g (sub soil) at point 2, from 0.084Mg/100g (bottom) to 0.442Mg/100g (top soil) at point 3. Nitrate (NO3) ranged from 3.336Mg/Kg (bottom) to 4.87Mg/Kg (top soil) at point 1, from 3.82Mg/Kg (bottom) to 4.687Mg/Kg (top soil) at point 2, from 3.838Mg/Kg (bottom) to 5.202Mg/Kg (top soil) at point 3.The range and the mean value of the
