an aquifer located within a petroleum processing plant in moín, costa rica, suffers hydrocarbon pollution. this study aimed to determine the ability of indigenous microorganisms from this site to degrade polycyclic aromatic hydrocarbons (pahs) to evaluate the feasibility of an eventual bioremediation process. aerobic conditions were found in the aquifer, while microbial analyses of the groundwa...

Anthropogenic activities and industrial effluents are the major sources of petroleum hydrocarbon contamination in different environments. Microbe-based remediation techniques known to be effective, inexpensive, environmentally safe. In this review, metabolic-target-specific pathway engineering processes used for improving bioremediation hydrocarbon-contaminated environments have been described....

This study was aimed at assessing the soil conditions of previously remediated oil spill sites in Niger Delta region. Ninety-six (96) samples were collected over two seasons from three states (Rivers, Abia, and Imo). Gas Chromatographic (GC) Analysis used analyzing for Total Petroleum Hydrocarbon (TPH) content while heavy metals analysis Lead (Pb), Zinc (Zn), Copper (Cu), Chromium (Cr) Iron (Fe...

Background: Polycyclic aromatic hydrocarbons (PAHs), which consist of fused conjugated aromatic rings, not only are toxic to humans and other living organisms, but will also pollute groundwater. These compounds can be point source or non-point source and are one of the most widespread organic pollutants. Some of them are suspected carcinogens and are linked to other health problems. This study ...

Background: Polybrominated Biphenyls (PBBs) and Polybrominated Diphenyl Ethers (PBDEs) are semi-permanent Halogenated compounds that are mainly used in flame retardant. These contaminants as endocrinedisrupting associated with dysfunction of immune, endocrine and nervous systems. Influence various physiological processes such as menarche, birth weight, fetus growth and development, head circumf...

plane and mulberry trees play a crucial role in purifying the polluted air in tehran as a majorcity. in this research, 13 main districts of tehran city were chosen as study area. 20 completely healthy planeand mulberry species were selected in similar ecological conditions and age range. the uptake of cd and pbwas determined using spectrophotometry, whereas the chlorophyll content was measured ...

The present study investigated the coupling effect of biodegradation and media filtration in treating hydrocarbon contaminated water. The study recorded reductions in total petroleum hydrocarbon, total dissolved solids, turbidity and microbial load. The study was essentially a simulated pump and treat process that involved the pumping of hydrocarbon contaminated water for treatment in a locally...

Crude oil is a viscous dark liquid resource composed by mix of hydrocarbons which, after refining, used for the elaboration distinct products. A major concern that many petroleum components are highly toxic due to their teratogenic, hemotoxic, and carcinogenic effects, becoming an environmental on global scale, which must be solved through innovative, efficient, sustainable techniques. One most...
