This study therefore investigate the Physicochemical parameters of street dust and… Continue Reading
Petroleum-based products are the major source of energy for industry and daily life. The technology commonly used for the soil remediation includes mechanical, burying, evaporation, dispersion, and washing. However, these Technologies are expensive and can lead to incomplete decomposition of… Continue Reading
This study was carried out in Udi, Udenu and Nsukka Local Government Areas, in Enugu state. The effects of liquid wastes from automobile workshops on some selected soil properties of the study area were investigated. Auger samples were collected at two depths, (surface, 0- 20cm) and (subsurface, 20- 40cm) of automobile wastes… Continue Reading
