Biological And Chemical Changes Associated With Exposure Of Cyprinid Fishes To Some Oil Field Chemicals In The Niger-Benue River System, Nigeria

摘要

Oil and gas exploration and production in Nigeria is geared towards meeting the energy need of its populace and also generate revenue. However, oil field chemicals used in oil and gas activities are sources of environmental pollution, causing various degrees of harm especially to the aquatic components of the environment. Most ascertained detrimental effects of oil field chemicals on organisms are generally laboratory based investigations. These have not considered synergistic and antagonists effects of these chemicals under various environmental conditions on organisms and the ecosystem. A research that incorporates both field and laboratory studies to investigate the effects of oil field chemicals in the natural environment would be of great use to provide a wholistic data for scientists. Such research would consider both synergistic and/or antagonistic effects of these chemicals under the natural environment with its varing conditions. The result obtained from such study would significantly enhance - integrated catchment management (ICM), further limnological studies/assessment, information for policy redress on contamination and pollution abatement, and remedial activities to ensure a sustainable healthy environment.
