ABSTRACT: Heavy metal concentration and physicochemical changes of soil treated with spent engine oil (SEO) and poultry manure after 12 weeks of growing Cyperus compressus was this study’s aim. Poultry manure (PM) was 10 % of 4000g (400 g) while the soil was 3600 g.
This study investigated the comparative profiling and bioaccumulation of PAHs in soil and Talinum triangulare harvested from charcoal production areas in Southern Nigeria. T. triangulare was cultivated in three sites (1, 2 and 3) in a charcoal production environment for seven weeks.
The concentration, distribution and sources of petroleum hydrocarbons in soils from selected areas in Abraka, Delta State, were evaluated. Soil samples were collected from areas suspected to be contaminated with petroleum hydrocarbons, which were also in proximity to human population. These areas included busy junctions, generator maintenance workshops, suya joint, drainage and fuel stations. Samples were extracted using nhexane/dichloromethane mixture and quantified using gas chromatograph-flame ionization detector.
