Evaluation of Cow-Dung Effectiveness for Bioremediation in Petroleum Polluted Loamy Soil Site
The development of local nutrients to enhance remediation of petroleum polluted soil mediums motivated this study. The study therefore, aimed at evaluating effectiveness of cow-dung for bioremediation of petroleum polluted loamy soil environment in the Niger delta area. The study was conducted in two distinct criteria, that is, petroleum polluted loamy soil with no Cow Dung Nutrient (NN) and petroleum polluted loamy soil with cow-dung Nutrient (WN) mediums. The two experimental set-ups were mixed manually to obtain homogeneity of impaction. Average weight measuring 3.2 kg Loamy Soil, Cow-dung 0.5 kg with ranging petroleum volume 50-190 ml for time ranging from 0 to 32 days at intervals of 25 ml petroleum and 4 days exposure time were used in the evaluation study. The evaluation was carried out based on Total Petroleum hydrocarbon (TPH) concentration CTPH as a function of petroleum quantity (v) discharged and exposure time (t).
