The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00066 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

RÉSUMÉ

There has been an increasing interest in the use of mushrooms in bioremediation of polluted habitats because of their ability to change the nutrient conditions in the soil and to accumulate metal ions, including heavy metals. Despite the upsurge in the research activities elsewhere, these studies are still in their infancy in Nigeria, which is one of the world’s leading oil producers. Lentinus squarrosulus Mont., a white-rot fungus, was tested for its ability to bioremediate a soil contaminated with 0.5–40% concentrations of engine oil over a period of 3 months. Results obtained revealed that in soils contaminated with engine oil and inoculated by L. squarrosulus, the amount of organic matter, carbon, nitrogen, and phosphorus increased, whereas the available potassium was reduced. A relatively high percentage degradation of total petroleum hydrocarbon (TPH) was observed in low concentrations of engine oil and a considerably lower percentage for the higher concentrations of engine oil. The metal concentration of Fe, Cu, Zn, and Ni increased with the increase of engine oil concentration up to 20%, followed by a decrease showing bio-accumulation by the white-rot fungus. The improvement of nutrient content values as well as the bioaccumulation of heavy metals at 20% engine oil concentration by L. squarrosulus is of importance for the mycoremediation of an engine-oil polluted soil.
