Effects Of Spent Engine Oil Pollution On The Germination Of Arachis Hypogaea Seeds
Chapter One: Background of the Study.
Groundnuts (Arachis hypogeal), often known as peanuts, are considered a nutritious snack. They are members of the Fabaceae family and originate in South America, Mexico, and Central America (FAO, 2002). It has also grown well in other regions of the world. It is one among the world’s main oilseed crops (Mukher et al. 2010).
It ranks fourth in oil production, following soybean, cotton seed, and rapeseed. China (40.1%), India (16.4%), Nigeria (8.2%), the United States (5.9%), Indonesia (4.1%), and Sudan (5.23%) are the world’s top groundnut producers (FAO 2002). Groundnut kernels can be eaten raw, roasted, or boiled, or the oil extracted from them can be used in cooking. Nigeria is Africa’s greatest groundnut producer (Sokoto et al., 2010).
The nuts are also utilised for animal feed and industrial raw materials (oil, cake, and fertilisers). This crop’s numerous applications make it a good cash crop for both local and foreign trade in a variety of developing and developed countries (Olawale and Ayo, 2000; Mukhter et al., 2009). Groundnuts and groundnut derivatives are extremely useful in the treatment of haemophilia and other inherited blood disorders.
People who suffer from nasal bleeding benefit from consuming groundnuts, and it also helps reduce excessive menstrual bleeding in women (FAO, 2002). Groundnuts are high in vitamins, containing at least 13 different types, including vitamins A, B, C, and E, as well as 26 essential minerals such as calcium, zinc, iron, boron, potassium, phosphorus, manganese, magnesium, copper, fat, sodium, water, proteins, carbohydrate, and fibre (Iwo and Obok, 2008).
Many of these materials promote brain function and growth, as well as bone strength. They are also high in antioxidants, which assist to reduce the risk of cardiovascular disease, cancer, and anti-aging, keeping the body youthful and fit.
Groundnuts are also high in five essential elements required by the body to sustain and repair tissues: dietary energy, protein, prosperity, thiamin, and niacin, hence they are especially advised to growing children and nursing moms. (Obasi. 2008).
Spent engine oil, also known as used lubricating oil, is recovered after servicing and then during oil from motor vehicles. In Nigeria, it is usual to dump wasted engine oil into gutters, water drains, open unoccupied plots, and farms, which is largely done by car and allied artisans with workshops on roadsides and in open spaces.
According to Agbogidi (2011a), wasted oil is the most prevalent soil contamination in Nigeria’s rural communities, where agriculture/farming is the primary source of income.
The utilised oil may contain harmful compounds, such as heavy metals, which might impact plant development, yield, and overall performance (Agbogidi and Egbuchua, 2010).
Although Anoliefo and Edegbai (2000), Vwioko and Fashemi (2005), Agbogidi (2009a), Agbodigi (2010a), Agbogidi (2010b), and Agbogidi (2011b) have studied the effects of spent oil contamination on plant growth, oil in soil has been shown to have a significant impact on plant growth, yield, and performance (Inoni et al., 2006, Ngoku et al., 2008, and Agbogidi, 2009b).
However, there is little published information on the influence of oil on groundnut growth. This study has been conducted in light of these circumstances. The current study aims to determine the impacts of wasted engine oil pollution on groundnut germination, growth, and development.
1.2 Justification.
The uses of Arachis hypogaea (Groundnut) in our time cannot be overstated because it serves as an alternative means of producing vegetable oil that is heart-healthy, has a wide range of health benefits, and provides food for both humans and animals.
It also generates funds for Nigeria as a country as well as for commercial and substantial farmers. Hence the requirement for this research work.
The findings of this study are expected to disclose the impacts of wasted motor oil pollution on the germination, growth, and development of Arachis hypogaea (Groundnut), as well as recommendations for ensuring proper Arachis hypogaea production.
1.3 Aims and Objectives
To investigate the impact of wasted engine oil pollution on the germination of Arachis hypogaea.
To investigate the effects of waste engine oil on the growth of Arachis hypogaea plants.
Determine the impact of used engine oil on leaf area, number of leaves, and plant height.
