This paper reviews the mechanistic and genetic effects of spilt crude oil and associated drill site chemicals on some Nigerian plants. Methods that range from morphological and physical observations, physico-chemical, anatomical, cuticular to cytological and cytogenetic analyses were reviewed. Quality data on various negative consequences of exposure of plants to pollution and contamination by crude oil-related pollutants were x-rayed. Proper legislation, monitoring and enforcement of sound environmental Laws by stakeholders were advised. Government collaboration with research institutions in order to keep abreast with new research findings was suggested as a way to help strengthen, manage and reinforce environmental Laws in order to protect our sources of food.
This work was carried out in collaboration between all the authors. Author FOA carried out the field and laboratory works, performed the statistical analyses, managed the analyses of the work, literature searches and wrote the first draft of the manuscript. Author JOO designed the study and supervised the field work. Author GOA managed the protocol and determined the concentration of the chemicals applied as treatments in the field work. All the authors read and approved the final manuscript.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
