KEYWORDS: HEAVY METALS IN TOP SOILS OF ABEOKUTA DUMP SITES

ABSTRACT:

The concentrations of copper. zinc. cadmium. lead and iron in top soils of refuse dump sites in Abeokuta were determined in order to asses.i the contribution of refuse in the dump sites to emironmental pollution. The only soil samples were collected from city dump sites each of which was about 100 metres away from a control site  Study samples and controls were pre-treated digested and anal"SCd using flame atomic absorption spectrophotometer. Results show that the range of copper was 65. n  <, <,UO mg/kg: iron 289.30 -360. IO mg/kg: lead 5.52 • 145.80 mg/kg; zinc 100.80 • 226 60 mg/kg and cadmium 4.M - 50.50 mg/kg in the refuse dump sites while the control sites had a range of 0.76 -4.54 mg/kg for copper. :U 77.06,,mg/kg for iron. 0.81 • 13.07 mg/kg for lead. S 125 • 71.43 mg/kg for zinc and 0.81 • 3.64 mg/kg for cadmium The large difference between the results obtained for refuse dump site and control site are statistically significant. indicating that the refuse dump sites arc sources of environmental metal pollution. It is recommended that indiscriminate dumping of refuse be discouraged
