“…The current detection of all the heavy metals such as; As, Cd, Cr, Pb and Ni that are of serious environmental concern in the SEO contaminated soils, is in line with the previous reports of Zali et al, (2015). The complete removal of As by the bacterial co-cultures adopted in this study could be ascribed to the same reason reported earlier by Hamer, (1986) ;Hameed, (2006) concerning the presence of powerful metal bio-sorbents in the bacteria such as the genus Bacillus.…”

“…Moreover, these authors reported that this poor management is the main source of constant release of spent oil discharged from the crank cases of cars and motorcycles, which may thus be aesthetically unpleasant and cause severe environmental pollution. Zali et al, (2015) revealed that the introduction of heavy metals analysis in engine oil aims to identify the failure of the oil components during the early stages before the emergence of major damages. They added that Iron (Fe), Chromium (Cr), Aluminium (Al), Lead (Pd), and Cadmium (Cd) known as wear metals may depict a significant wear in engine or any oil wetted compartment in an automobile.…”

“…However, Aucelio et al, (2007) previously reported that the detection of Silicon (Si), Sodium (Na) and Boron (B) as wear metals may have arisen from dirt and antifreeze, thus resulting into failure of the system. Zali et al, (2015) added that SEO should be managed appropriately according to the standard international regulations, and it can be recovered also from those engines that have potential economic values. These authors further submitted that SEO that does not meet the set of standards and regulations can be categorized as wastes and must be disposed of.…”

This study was conducted to assess the decontamination of heavy metals of an environmental concern in spent engine oil (SEO) contaminated soil, through the adoption of Staphylococcus aureus and Bacillus cereus cocultures, isolated from Dutse mechanic village, Nigeria. About 1.5 kg of autoclaved soil was contaminated with SEO at three levels. The sterilized soil was then amended with compost, powdered cocoa pod husk (CPH), and powdered cow dung (CD). Subsequently, bio-augmentation with bacterial co-cultures (150 ml) was done. Heavy metal concentrations; Arsenic (As), Cadmium (Cd), Chromium (Cr), Nickel (Ni) and Lead (Pb) were estimated at the commencement, at the fifth and tenth week of the study. The factorial experiment was laid out in a completely randomized design (CRD). Results indicate that bio-stimulation adopted through the amendments did not have significant effects on the bacterial decontamination of soil especially at the 5 th week (P> 0.05). CD only influenced the decontamination of Cd at 5% contamination level (0.0008 mg\ kg), compared with compost that recorded the least effect (0.00360 mg\ kg) at the 5 th week. Meanwhile, CPH had the highest decontamination effect on Cr (0.004 and 0.000 mg\ kg) at 10% and 15% contamination levels; respectively, at the 5 th week. However at the 10 th week, complete removal of As was influenced by compost, CPH, and CD using 5%, 10% and 15% SEO contamination levels, respectively (P< 0.05). The decontamination efficacies of S. aureus and B. cereus recorded in this study is an indication of their potentialities for application in bioremediation of heavy metals.

Наведено методику та результати дослідження вмісту важких металів у зразках нафти з двох основних нафтогазоносних провінцій України. Проведене оглядове моделювання ймовірних шляхів надходження важких металів у вуглеводневу сировину. За результатами дослідження, зроблене порівняння властивостей в залежності від хімічного вмісту зразків. Визначені ймовірні причини розбіжностей концентрацій важких металів у нафтах з різних геологічних структур Ключові слова: важкі метали, рентгенофлуоресцентна спектроскопія, геохімія нафти, хімічний склад, металоорганічні сполуки

“…Macian et al [20], Wang et al [21], and Ali et al [15] measured iron, aluminum, copper, chromium, and lead wear particles in engine oil. The source of oil foreign particles may be engine wear (e.g., iron, aluminum, and chromium), external contamination (e.g., silicon, sodium, and bromine), or useful additives (e.g., calcium and zinc) [22]. Spectroscopic methods used to determine the amount of oil particles are inductively coupled plasma (ICP) and atomic absorption spectroscopy (AAS) [23].…”

Effect of Calcite and Silica Content on Tribological Performance of Engine Oil Lubricants

Sand dust can enter into an engine lubrication system through the intake manifold. The effect of calcite and silica sand dust particles in an engine on oil particle contamination was investigated. The presence, amount, and size of silica and calcite particles in engine oil were determined using X-ray diffraction (XRD), inductively coupled plasma (ICP) spectroscopy, and energy dispersive X-ray spectroscopy (EDX). Four levels of silica and calcite particles were obtained through engine oil sampling from farm tractors at the east of Isfahan (Iran) then, used to investigate their effect on the wear of engine moving parts after 20 hours of engine operation. The ICP analysis showed the amount of iron, aluminum, chromium, copper, nickel, and lead increased in the engine oil with increasing silica content, whereas aluminum and copper increased as the calcite content increased.
