Abstract
Most household and some industrial solid wastes end up in the landfill which is the commonest means of solid waste management in many parts of Baylesa state, Nigeria. This study assessed the physicochemical characteristics, particle size distribution and total hydrocarbon content in soil samples from abandoned landfill site in Igbogene, Bayelsa state, Nigeria by collecting samples from varying distances (50m, 100m and 150m) at a depth of 0-20cm and analyzed using standard methods. Results were in the range of 5.01 – 5.34 (pH), 0.73 – 0.98 meg/100g (Exchangeable Acidity), 2.45 – 3.48 meg/100g (sodium), 0.19 – 0.31 meg/100g (potassium), 3.94 – 5.33 meg/100g (calcium), 1.52 – 2.15 meg/100g (magnesium), 9.57 – 11.49 mg/kg (nitrate), 4.18 – 5.19 mg/kg (sulphate), 6.99 – 8.85 mg/kg (available phosphorus), 8.23 – 12.60 mg/kg (total hydrocarbon content), 76.48 – 100.25 mg/kg (chloride), 5.14 – 7.59 mg/kg (ammonium), 8.83 – 8.95% (clay), 2.70 – 3.10% (silt), 87.93 – 88.35% (sand), 2.62 – 3.58% (organic carbon), 4.51 – 6.16% (organic matter) and 0.22 – 0.33% (total nitrogen). Analysis of variance (ANOVA) showed no significant deviations (p>0.05) across the various distances for all parameters except for organic carbon and matter, total nitrogen, potassium and ammonium. In addition, most of the nutrients showed positive significant relationship at p<0.05. This suggests that at large the activities of old landfill in the study area is not influencing the soil characteristics under study. Rather the apparent decline in value away from old landfill may be due to mobility level of minerals in the soil toward the southwest direction, which the cluster analysis clearly showed.

Highlights
Solid wastes and / or liquid waste discharged into the surface water and or close to surface water could alter the characteristics of the receiving water (Uzoekwe and Achudume, 2011)
The objective of this study is to evaluate the physicochemical characteristics, particle size distribution and total hydrocarbon content in soil samples obtained from abandoned landfill site in Igbogene, Bayelsa State, Nigeria
The general characteristics, particle size distribution and total hydrocarbon content in the old landfill in Igbogene community, Bayelsa State Nigeria is presented in the Table 1 below
Summary
Many human activities are being carried out in the soil of Niger Delta region As such many wastes streams including solid and liquid from food processing sectors such as garri and palm oil production (Izah et al, 2016), effluents from refineries and crude oil production processes (Uzoekwe and Nwachokor, 2012; Uzoekwe and Achudume, 2011), are discharged into the environment with little or no treatment. The objective of this study is to evaluate the physicochemical characteristics, particle size distribution and total hydrocarbon content in soil samples obtained from abandoned landfill site in Igbogene, Bayelsa State, Nigeria. Anions present (chloride, sulphate and nitrate) were determined titrimetrically according to AOAC (1984) method
