Effect of crude oil pollution on the rhizosphere microbial communities of Mangifera indica L and Elaeis guineensis Jacq in Rivers State, Nigeria
This study investigated the effect of crude oil pollution and remediation on the fungi and bacteria communities of M. indica and E. guineensis rhizospheres using three sites – Unpolluted Site (UPS), Polluted and Treated Site (PTS), and Polluted and Untreated Site (PUS). Population of fungi in both M. indica and E. guineensis rhizospheres was highest […]
Determinants of tree-planting in a semi-urban community in south-western Nigeria
Without trees, human life would be unsustainable. Trees provide a wide range of products (timber, fruit, medicine, beverages, fodder and oils) and life-supporting services (carbon sequestration, erosion control, soil fertility, shade and beautification). However, our trees and forests are rapidly disappearing at an alarming rate with about 4 billion trees cut down annually and an […]

Assessment of heavy metals (Pb, Cd, Zn and Cu) concentrations in soils along a major highway in Wukari, North-Eastern Nigeria
Heavy metal pollution is a major environmental problem, especially around highways with high traffic density. This study investigates the levels of Pb, Cd, Zn and Cu in roadside soils of Wukari section of the Wukari-Jalingo highway, Taraba state, Nigeria. Samples were randomly collected and analyzed using standard methods. The mean concentrations (µg/g) of Pb, Cd, […]
In vitro antioxidant and antiglycation studies on african mistletoe (T. bangwensis (Engler and K. Krause), Danser) and ring worm plant (S. alata (Linn.) Roxb) from Nigeria
The antioxidant activity of crude methanolic extracts and fractions of African mistletoe (Tapinanthus bangwensis) and Ring worm plant (Senna alata) leaves from Nigeria was investigated. In an in vitro free radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH), superoxide scavenging (SOS) activity and chelation of iron (II) ion [Fe2+] in the presence of ethylenediaminetetraacetic acid (EDTA), ethyl […]
