Abstract

This study assessed the concentrations and ecological risks of heavy metal contamination in mangrove swamp sediments across four communities in Nembe LGA, Bayelsa State: Sounikiri, Ikrikokiri, Odekiri and Obiama. Obiama sampling point served as the geochemical background due to its relatively undisturbed ecosystem. Sediment samples were collected using standard methods at two depths (0–10 cm and 10–20 cm), except at the geochemical background location (Obiama), where samples were taken at a depth of 0–20 cm. The concentrations of cadmium (Cd), chromium (Cr), copper (Cu), manganese (Mn), lead (Pb), and zinc (Zn) were determined using standard procedures. Statistical analyses were conducted to assess significance at p
