The impact of Cow Dung Augmentation for Remediation of Crude Oil Polluted Soil by <i>Eleusine indica</i>

Abstract

This study was conducted to evaluate the Enhancement of Remediation by Eleusine indica through augmentation of soil with cow dung. The soil was contaminated artificially with 50kg, 75kg and 100kg crude oil. over 8 weeks period. The study included an assessment of the polycyclic aromatic hydrocarbons (PAHs) and heavy metal (Cd and Pb) accumulation in soil of Eleusine indica.More PAHs was lost from soils augmented with cow dung than from the non-augmented soil. The heavy metals (lead) were in the augmented soils than from the non augmented soil, while heavy metal (cadmium) shows an insignificant amount. Significant differences were noticed between the augmented soils and the non-augmented soil (p<0.05). The results obtained in this study show that augmenting crude oil polluted soils with cow dung will enhance remediation and restoration of crude oil polluted soil. © JASEM http://dx

Enhancing the Phytoremediation of Hydrocarbon-Contaminated Soils in the Sudd Wetlands, South Sudan, Using Organic Manure

“…is diversion slows down the process of phytoremediation as was observed in some studies such as Essien et al [30] that excess application of cow dung has the potential of causing the existing microbes to abandon crude oil and turn to feeding on the nutrients provided by the cow dung.…”

“…is assertion rhymes Oyedele and Amoo [33] that addition of cow dung manure improves on the calcium, magnesium, phosphorus, potassium, and nitrogenous contents which are vital elements for better growth of plant species. Essien et al [30] also observed that the ubiquitous nature of cow dung reduces the cost of using inorganic fertilizers which further reduces the cost of cleaning up crude oil contaminated soils. In this study, there is a nonsignificant difference between use of manure 5 gkg −1 soil and 10 gkg −1 soil.…”

“…e usefulness of cow dung and other biostimulants have been previously reported. In Nigeria, Essien et al [30] using Eleusine indica established that augmenting crude oil polluted soils with cow dung enhances its remediation potential leading to restoration of polluted soils. Njoku et al [31] found the same effect using Glycine max; Isaac [32] used Panicum maximum and Talinum triangulare; and Oyedele and Amoo [33] confirmed similar results using Maize plant while Omara et al [34] used Sorghum Bicolor L. (Moench) in petroleum adulterated soils from an automobile repair workshop in Kampala city, Uganda.…”

Phytoremediation: green technology for improving aquatic and terrestrial environments

“…For example, inorganic pollution could be treated by phytostabilization, phytovolatilization and rhizoremediation methods (Cunningham et al, 1996;Nwoko, 2013) based on their physicochemical characteristics and concentration as well as their biodegradability. Phytoremediation process can be enhanced through soil conditioners, such as compost (Mangkoedihardjo, et al, 2008), cow dung (Essien et al, 2015;Njoku et al, 2012), olive waste (Nogales and Benítez, 2006), rhizobacteria (Gurska et al, 2009;Langella et al, 2014), biochar (Houben et al, 2013), adsorbent (Mojiri et al, 2016), and plant growth promoters (Vamerali, 2011). The main target of this review is to present different merit aspects of phytoremediation as green technology and their eligibility for environmental cleaning.…”

Optimization of nutrients requirements for bioremediation of spent-engine oil contaminated soils

“…Several studies have been conducted to investigate the impacts of nutrients-induced biostimulation strategy on indigenous soil microorganisms' capacity to biodegrade soils contaminated by petroleum products, including spent-engine oil [5,[22][23][24][25][26][27]. Bioremediation of used motor oil contaminated soil using elephant and horse dung as stimulants was conducted by [25].…”
