Evaluating the use of spiny pigweed (<i>Amaranthus spinosus</i>) and water leaf (<i>Talinum triangulare</i>) for bioremediation of crude oil polluted soil in Ikarama Community in Bayelsa State Nigeria

Abstract

ABSTRACT:The potential soil amending impact of various concentrations of macerated roots of Amaranthus spinosus and Talinum triangulare singly and in combination on crude oil polluted soil of Ikarama community of Yenagoa in Bayelsa State Nigeria was investigated using gas chromatography technique for twelve weeks. The polluted soil was bagged in seven groups with the addition of 250g of Amaranthus spinosus root, 500g of Amaranthus spinosus root, 250g of Talinum triangulare root, 500g of Talinum triangulare root, 250g of combined roots of Amaranthus spinosus and Talinum Triangulare, 500g of combined roots of Amaranthus spinosus and Talinum Triangulare and labelled as follows Ga, Gb, Wa, Wb, GWa and GWb respectively; and a polluted and not amended bag which served as control. Each bag contained 1000g of polluted soil. The Total Petroleum Hydrocarbon (TPH), Polycyclic Aromatic Hydrocarbon (PAH), pH and enzyme concentration were analysed at intervals of four weeks for twelve weeks. The result showed that TPH reduction in the impacted soil varied between 29.5% for Ga and 1.79% for Wa after week 4.The results also showed that PAH reduction varied between 53% for Gb and 14.2% in GWa at week 12 (p<0.05). The results suggested that the roots of the plants Talinum triangulare and Amaranthus spinosus are best used singularly and not in combination in the bioremediation of TPH and PAHs. © JASEM https://dx.doi.org/10.4314/jasem.v21i5.16

Growth Performance of Grain Amaranth (Amaranthus Cruentus L.) on Spent Engine Oil Contaminated Soil Bioremediated With Two Bacterial Co-Cultures and Organic Amendments

“…The prospect of bioremediation technology in effecting desirable reclamation of polluted environment has been reported by Okoye et al (2017); Sivaramakrishnan et al (2021) coupled with the employment of amaranths for bioremediation studies which Chinmayee et al (2012); Rehaman et al (2020) have submitted to have produced promising results over the years. The ability of suitable organic amendments to facilitate operational reclamation of SEO polluted soil has equally been reported by Osaigbovo et al (2013).…”

Talinum fruticosum: A Potential Multi-value Plant: A Review

“…Hence, this plant has a potential to be used as plant for phytoremediation. It degrades polycyclic aromatic hydrocarbon and total petroleum hydrocarbon from crude oil polluted soils (Okoye et al, 2017).…”

A Systematic Review on Amaranthus-Related Research

“…The nutraceutical values of amaranths have been reported widely in scientific publications [13,15,21,[43][44][45]. Findings from different experiments have indicated that Amaranthus has a higher proximate composition than commonly consumed food crops, such as corn (Zea mays), buckwheat, rye, and rice [15]; comparable nutritive characteristics to commonly patronized vegetables, e.g., spinach (Spinacia oleracea L.) [31]; equivalent nutrient content to some fodder crops, such as barley, maize, and wheat [46]; and is rich in extremely rare amino acids (e.g., lysine and tryptophan) that could replace animal protein and supplement human diets with moderate-quality amino acids [47,48]. Metabolic diseases, such as diabetes, ulcers, congestive cardiac, liver, and renal failure, cancer, helminthic infections, and most degenerative diseases, such as ageing hypertension, atherosclerosis, obesity, and being chronically underweight are induced by damages done to cells and tissues by free radicals [17,[49][50][51][52].…”
