Assessment of Heavy Metal Levels, Pollution Indices and Ecological Risks of Floodplain Sediments in Urban Areas in Delta State, Nigeria

The aim of this study is to assess heavy metals levels, pollution indices and ecological risks of floodplain sediments in urban areas in Delta State, Nigeria. The levels of nine heavy metals (Cd, Pb, Cr, Ni, Cu, Co, Mn, Zn and Fe) were measured in floodplain sediments of urban areas in Delta State, Nigeria. Sediment samples from the nine urban areas were collected for three months (July-September) covering the wet season. The sediment samples were digested with aqua regia, and the heavy metal levels in the digests were quantified by means of atomic absorption spectrometry.

An Overview of Flood Disaster Management in Nigeria

Flood can be seen as a process that bring about a short-term immersing of a land with water that does not ordinarily occur. It is one of the most common environmental hazards in developing countries like Nigeria. Flooding, a recurrent events in Nigeria occur mostly in locations that are flat or low lying especially places with inadequate or no surface drainages, or where existing ones have been filled with refuse and other sediments. The exposure to flooding is due to a range of socio-economic factors, like income, occupation, information technology, access to loan facilities, etc.
