Abstract

Warri/Effurun area is heavily industrialized and over populated both domestic and industrial waste are dumped in various spots. Top and depth soils from waste dumping sites were determined for some selected trace elements such as lead, mercury, chromium, arsenic, selenium and cadmium. The soils were digested in acid mixture and the metals were determined using atomic absorption spectrophotometry. This study was carried out monthly for the period covering July 2001 - June 2002. Metal contents in contaminated soils (E1 - E6) were higher than those of uncontaminated control soils (E7 and E8). These high levels of metals in soils from E1 - E6 were as a result of wastes dumped. Spearman rank order correlation coefficient showed that strong relationships were found for all the metals (P < 0.01) between top soils and depth soils.
