“…Additionally, COWS and its components are substantially cytotoxic, mutagenic and carcinogenic, especially polycyclic aromatic hydrocarbons (PAHs) [1,2]. Environmental pollution with COWS has also been linked to physical and chemical changes of natural habitats, with potential lethal and sub-lethal toxic effects on aquatics and terrestrial ecosystem [3]. As consequence, COWS has been classified as a hazardous organic contaminant that must be treated before discharge into environment [4,5].…”

“…The challenges confronting oil refineries and petrochemical industries to meet the regulatory requirements has given rise to research interest on safe disposal and treatment technologies for crude oil wastes sludge [3]. Amongst the currently available methods, bioremediation technologies, involving the use of microorganisms to degrade crude oil waste sludge stands out as a greener approach.…”

“…One hundred and twenty animals were used with six animals in groups 1 and 2 and 18 animals in groups 3-8 respectively. Each treatment regimen groups (3)(4)(5)(6)(7)(8) was further sub-grouped into Pre-T, Co-T and Post-T consisting of six rats. While rats in the control group (Group I) served as control and were not exposed to any form of treatment except feed and water.…”

“…2 Today, the Niger-Delta region of Nigeria have lost most of its agricultural lands and water bodies due to contamination through oil exploration activities or stands a potential risk of being polluted. [3][4][5][6] It is on record that this is a public health challenge as many inhabitants have reportedly died of several forms of diseases especially diseases arising from mild to chronic kidney failures in inhabitants of the region. 7,8,9 With the reality of these disease occurrences and burden increasing daily, there is no doubt that man must find a way to significantly reduce the rising trend.…”

its fruit and oil has been harvested and processed remains a potential adjuvant for this course. This is so because studies revealed that it is rich in phytochemicals and has several medicinal values. 11,12 However, recent studies by Achuba 13 revealed that incorporation of dried oil palm leave powder in crude oil-polluted meals significantly prevented the negative outcomes accompanying crude oil toxicity. This investigation was aimed at assessment of different regimen of oil palm leaf extracts against crude oil-adulterated feed mediated nephrotoxicity. Materials and Methods Collection of palm leaves, crude oil and reagentsHarvest of Elaeis guineensis leaves were done at Ovwor Mixed Secondary School in Ughelli, Delta State, Nigeria on May 11, 2016. This was immediately rinsed with water to remove all forms of dirt and taken to the laboratory. The leaves were identified at Forestry Research Institute of Nigeria, Ibadan where voucher number, F101173 was assigned. The crude oil, Escravos blend type, was obtained from Warri Refining and Petrochemical Company, Warri, Nigeria. The reagents used were analytical grade. Experimental animalsMale albino rats (One hundred and twenty) were sourced from Faculty of Basic Medical sciences, Delta State University, Nigeria. The weights of the rats were taken and it ranged from 148 to 180 g. The experimental rats were maintained on grower's mash and exposed to laboratory environment for two weeks. This is to enable them acclimatize to the feed and the new environment. Ethical approval, with the number REC/FOS/19/01, for the use the animals was granted by the ethical committee,

“…Crude oil is very important in various parts of the world and its products are used as fuel for automobiles. It is also useful in the generation of electric power (Ohanmu et al, 2019). In Nigeria, crude oil is produced in the Niger-Delta region and this region has a land mass of about 70,000km 3 , 7.5% of the total land mass of Nigeria with two rivers (rivers Niger and Benue), that drain into the Atlantic Ocean.…”

The rising level of infertility in the females have been associated with environmental pollutants and one such pollutants is crude oil. Crude oil pollution occurs in the Niger-Delta region of Nigeria and interaction with this toxicant by both humans and animals may adversely the female reproductive system. This study was designed to investigate the effect of crude oil contaminated water on reproductive functions in female Wistar rats. Fifteen (15) female rats weighing between 140g-230g were used for this study and the rats were divided into three (3) groups (1, 2 and 3) and each group had five rats. Group 1 was the control group while group 2 and 3 were the test groups receiving 2.5mls and 5mls of crude oil contaminated water twice daily for four weeks. The stages of Oestrus cycle of the rats were checked daily. The rats were sacrificed after four weeks and the blood collected were used for hormonal assays (Follicle stimulating hormone (FSH), Luteinizing hormone (LH), Testosterone).The uterus and ovaries were used for histology (Haematoxylin and Eosin staining), Superoxide dismutase (SOD) activity and Malondialdehyde (MDA) concentration. The results were analyzed using GraphPad Prism software for windows and data were expressed as mean±standard error of mean. Statistical significance was accepted at p<0.05.
