Short-term in situ Exposure of Guinean Tilapia and Blue Crab Near a Sawmill Wastes-impacted Coastal Ecosystem Reveal Significant Oxidative Stress Effects

Abstract

Paper summary generated by OpenAI: This study investigates the oxidative stress effects on Guinean Tilapia (Coptodon guineensis) and Blue Crab (Callinectes amnicola) following short-term in situ exposure near a sawmill waste-impacted coastal ecosystem. Over a 28-day period, the concentrations of polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCPs) were analyzed in surface water and sediments, revealing significantly higher levels at the test site compared to a reference site. Correspondingly, oxidative stress indices in both species showed marked increases, indicating adverse impacts from sawmill waste. The findings underscore the need for sustainable waste management practices to protect aquatic life in affected ecosystems.
