Effect of concentration and contact time on heavy metal uptake by three bacterial isolates
The effect of heavy metal concentration and contact time (exposure period) on heavy metal up take by pure cultures of three bacteria (Pseudomonas, Bacillus and Aeromonas ) isolated from a crude oil impacted brackish aquatic system in the Niger Delta were investigated. Heavy metals employed included metals found in this Bonny light crude oil (Fe, Zn, Cd, Cu, Ni and Pb). Accumulation of...
Evaluation of heavy metals in roadside soils of major streets in Jos metropolis, Nigeria
A study of heavy metals in roadside soils is critical in assessing the potential environmental impacts of automobile emission on the soil. The soil samples were collected and analyzed for the levels of Pb, Zn, Mn, Cu, Ni, Cd, Co and Fe using AAS. Results indicate the decreasing order of the average total metal content for the studied metals: Fe > Zn > Mn > Pb > Cd > Cu. Except for Cd, all...
