Download Effects of Crude Oil on Some Bacteria and Mineral Constituents of Rhizosphere of Delonix Regia Hook. Crop Production and Science students who are writing their projects can get this material to aid their research work.

Abstract

Crude oil spill is hazardous to soil and subsequently affects food production. Certain plants however tolerate and/or improve the mineral deficiency imposed by crude oil.

Also, due to the ability of bacteria to degrade crude oil, plants that enhance the abundance of soil bacteria under pollution have been under investigation.

The effects of crude oil on the bacterial count and mineral constituents of soil rhizosphere of Delonixregia were investigated. The effects of D. regia on total bacterial count and mineral constituents were tested.

A total of 96 polythene bags were filled, each with 18 kg of soil. Four soil bags each containing a seedling of D. regia and four without seedlingwere polluted with 30 ml of crude oil.

This was repeated using 150 ml and 750 ml of crude oilwhile the control was not polluted. The experiment was set up in 3 replicates in a completely randomized design.

Introduction

Crude oil is physically, chemically and biologically harmful to soil because it contains many toxic compounds in relatively high concentrations (Franco et al., 2004).

Soil  contamination can result in soil degradation, bring great loss to agricultural production and pose threat to human health (Lijuan, 2012). Crude oil spill is a common event in Nigeria especially in the Niger Delta areas of the country.

Spills may arise from oil well drilling, production operations, transportation, refining, storage and marketing. It could also be from anthropogenic sources such as sabotage or accidental spills such as ruptured oil pipelines (Oberdorster and Cheek, 2000).

Presently there are eleven oil corporations operating about 159 oil wells in Niger Delta region of Nigeria. Record indicates that the Niger Delta region of Nigeria experiences on the average, 273 oil spills resulting to about 115,000 barrels of crude oil annually from 1983- 2005.

Some recent oil spill in Nigeria include Assa-Rumekpe pipeline at Elele Alumini in 2014, Amukpe trunk line at Amukpe in 2011, Nkpoku Bomu pipeline at Ekporo in 2014, Nun-river Kolo creek at Oporoma in 2013 (SPDC, 2014).
