Characteristic levels of heavy metals in sediments and dredged sediments of a municipal creek in the Niger delta, Nigeria
TLDR
In this article, the authors found that significant concentrations of heavy metals are accumulated more on the surface (0-15cm depth) of the dredged material as compared to the sub surface (15-30cm) and post dredged sediments.About:

Metal concentrations in water, sediment and sharptooth catfish Clarias gariepinus from three peri-urban rivers in the upper Manyame catchment, Zimbabwe
TL;DR: In this paper, the authors measured the concentrations of zinc, cadmium, chromium, nickel, lead, copper and iron in the tissues of sharptooth catfish Clarias gariepinus from three rivers in the upper Manyame catchment over seven months in 2008-2009.

Concentrations and Distribution of Trace Metals in Water and Streambed Sediments of Orogodo River, Southern Nigeria
TL;DR: In this paper, the distribution of Cd, Pb, Ni, Cr, Cu, Mn, Fe, and Zn in sediment and surface water, and some physico-chemical characteristics of Orogodo river sediments, were evaluated.
Distribution of Trace Elements in Surface Water and Sediments from Warri River in Warri, Delta State of Nigeria
TL;DR: In this paper, the authors provided information on the concentrations and distribution of selected heavy metals in surface water and sediments from Warri River, and to compute a contamination/pollution index of heavy metals.

Trace elements in sawdust particles in the vicinity of sawmill in Sapele, Nigeria.
TL;DR: The levels of these trace elements observed in the sawdust particles exceeded permissible occupational exposure limits and constitute serious health risk to human and the environment in general.

TL;DR: Compared to more industrialized regions and with the exception of some hot-spot sites, the concentrations of heavy metals in African aquatic systems were low and close to natural background levels; in view of the expected increase in urbanization and socio-economic activities in Africa, sources and quantities of heavy metal discharges to aquatic environments have to be identified.

Heavy metals and organisms in the Lagos Lagoon
TL;DR: Levels of cadmium, cobalt, copper, chromium, iron, manganese, nickel, lead and zinc were determined in the water and in some fish and shellfish in the Lagos Lagoon as discussed by the authors.

Heavy metal contamination of vegetables and soil in domestic gardens around a smelting complex
TL;DR: In this article, high levels of copper, zinc, lead, cadmium, nickel, and iron are reported in leaf vegetables grown in domestic gardens in close proximity to the copper smelter in Wollongong, New South Wales, Australia.

Distribution of Cr, Pb, Cd, Zn, Fe and Mn in Lake Victoria sediments, East Africa
TL;DR: The authors found increased concentrations of lead and other trace metals in Lake Victoria and found the distribution pattern of heavy metals in tropical freshwater systems has been little studied.
