“…Cessation of Hb and RBCs with an increased percentage of erythroblast abnormalities due to pollution was also found in striped catfish [18] and common carp, Cyprinus carpio [15] , [42] . Similarly, Gurung et al [43] reported that crude oil exposure during organogenesis induced greater teratogenic effects on halibut, disturbances cardiovascular flow of embryonic Gulf killifish. We found that both of the treatment group displayed greater WBC number after diesel exposure.…”

“…A reduction in cardiovascular performance was observed in the Gulf killfish ( Fundulus grandis ) exposed to oil. The hatching success of the killfish eggs was also reduced when they were exposed to crude oil (Gurung et al 2021 ).…”

Crude oil exploration is a source of significant revenue in Africa via trade and investment since its discovery in the mid-19th Century. Crude oil has bolstered the continent’s economy and improved the wellbeing of the citizenry. Historically, Africa has suffered from conflicts due to uneven redistribution of crude oil revenue and severe environmental pollution. Advancements in geophysical survey techniques, such as magnetic and gravity methods, to seismic methods, have made the commercial exploration of crude oil possible for some other countries in Africa apart from Nigeria, Angola, Algeria, Libya, and Egypt. The occurrence of organic-rich, oil-prone Type I, II, and mixed II/III kerogens in sedimentary basins and entrapment within reservoir rocks with intrinsic petrophysical properties are majorly responsible for the large deposits of hydrocarbon in Africa. The unethical practices by some multinational oil corporations have resulted in social movements against them by host communities and human rights groups. The unscrupulous diversion of public funds, award of oil blocks, and production rights to certain individuals have impaired economic growth in Africa. The over-dependence on crude oil revenues has caused the economic recession in oil-producing countries due to plummeting oil prices and global pandemic. Most host communities of crude oil deposits suffer from a lack of infrastructure, arable soils, clean water, and their functioning capabilities are violated by crude oil exploratory activities, without adequate compensations and remedial actions taken by oil companies and the government. Thus, this review examines crude oil exploration in Africa and provides insight into the environmental and socio-economic implications of crude oil exploration in Africa. Furthermore, this report highlights some recommendations that may ensure ethical and sustainable practices toward minimizing negative impacts and improving the quality of life in affected communities.

“…[81] Have concluded that exposure of embryonic stages of Atlantic cod (Gadus morhua) fish to oil can lead to larval mortality and morphological deformities. Exposure during the embryonic period (pre-hatch) of haddock larvae (Melanogrammus aeglefinus) resulted in reduced eye size and increased incidence of abnormal eye morphology, also oil-exposed fish had reduced mean blood flow speed, flow rate, and flow pulsatility [82,83]. Also, dispersion of oil droplets can contribute to the toxicity of the exposure medium as the droplets can behave like a reservoir for toxic components which can be harmful to fish health.…”

Accidental oil spillages can release millions of barrels of oil into the marine environment threatening aquatic wildlife like fisheries. As a part of the oil spill response strategy, several chemical dispersants have been recommended that have been successfully used elsewhere. However, the adverse effects of dispersed oil are unknown to fish species in Kuwait. Therefore, this study investigated the toxicity of water-accommodated fraction (WAF) and chemically enhanced water-accommodated fraction (CEWAF) of Kuwait crude oil (KCO) with three dispersants (Corexit® 9500, Corexit® 9527, and Slickgone® NS) against the larvae of the sobaity sea bream Sparidentex hasta which is of an international economic significance. Total petroleum hydrocarbons (TPH) were used for comparison of chemical compounds partitioned in WAF of dispersed and non-dispersed oil. Toxicity test results with fish larvae showed that WAF of non-dispersed oil and Corexit® 9527 treated CEWAF had similar LC 50 values (0.12 g oil. l -1 ) whereas CEWAF's of Corexit® 9500 and Slickgone® NS CEWAF showed lower toxicity.
