Sex-Specific Responses to Hydrocarbons Toxicity Using Multiple Biomarkers in the African Catfish
What is it about?
Polycyclic aromatic hydrocarbons (PAHs) are priority pollutants that are major constituents of petroleum. Their occurrence in the aquatic environment emanates from petroleum-related processing and wastewater. Their effects have been studied in various aquatic organisms. However, there is a scarcity of studies on sex-specific responses of model aquatic organisms to these ubiquitous pollutants. We utilised multiple biological endpoints to evaluate the responses of male and female sexually mature African Sharptooth Catfish to near environmental concentrations of 2-ringed (Naphthalene), 3-ringed (Phenanthrene) and 4-ringed (Pyrene) PAHs.
Why is it important?
Our results demonstrate sex-specific responses and the utility of multiple biological responses across various levels of biological organisation for holistic evaluations of polycyclic aromatic hydrocarbons in ecotoxicological studies.
