Seasonal Metal Distribution in Ondo Coastal Sediment, Nigeria

Abstract

The distribution of heavy metals in streambed sediment from an oil-producing region in Nigeria has been examined between the two distinct seasons (dry and wet). The highest mean concentration during the dry season (wet season in brackets) was 2083.3±355.5 (2264.2±347.3)mg/kg Cu and 0.16±0.06 (0.19±0.09)mg/kg Zn respectively. With similar patterns at both seasons, the order of increasing concentration was Zn
