Petroleum hydrocarbons are naturally occurring flammable fossil fuels used as conventional energy sources. It has carcinogenic, mutagenic properties and is considered a hazardous pollutant. Soil contaminated with petroleum hydrocarbons adversely affects the properties of soil. This paper aim to remove pollutants from the environment is an urgent need of the hour to maintain the proper functioning of soil ecosystems.

The ability of micro-organisms to degrade petroleum hydrocarbons makes it possible to use these microorganisms to clean the environment from petroleum pollution. For preparing this review, research papers and review articles related to petroleum hydrocarbons degradation by micro-organisms were collected from journals and various search engines.

Various physical and chemical methods are used for remediation of petroleum hydrocarbons contaminants. However, these methods have several disadvantages. This paper will discuss a novel understanding of petroleum hydrocarbons degradation and how micro-organisms help in petroleum-contaminated soil restoration. Bioremediation is recognized as the most environment-friendly technique for remediation. The research studies demonstrated that bacterial consortium have high biodegradation rate of petroleum hydrocarbons ranging from 83% to 89%.

Proper management of petroleum hydrocarbons pollutants from the environment is necessary because of their toxicity effects on human and environmental health.

This paper discussed novel mechanisms adopted by bacteria for biodegradation of petroleum hydrocarbons, aerobic and anaerobic biodegradation pathways, genes and enzymes involved in petroleum hydrocarbons biodegradation.

Corporate social responsibility (CSR) is an important corporate activity that affirms the importance of giving back to the community. This research aims to examine the CSR practices of Palestinian Islamic banks and their contribution to socio-economic development. There is an ongoing debate regarding Islamic financial institutions’ profit motive versus their motivation to achieve human welfare. The Palestinian Islamic banks are not disconnected from this debate, and this paper aims to discuss this issue.

For the purpose of assessing the CSR practices of Palestinian Islamic banks, a secondary analysis of the banks’ annual reports was carried out. In addition, 11 structured interviews were conducted with Islamic banks’ practitioners at the decision-making level and with some of the banks’ Sharīʿah board members to gather their views on CSR. These have been analyzed in light of the actual CSR practices disclosed in each bank’s annual reports.

The main research findings suggest that the CSR practice is highly valued by the Palestinian Islamic banks, but it is small and has marginal effects on the community’s socio-economic development. Another important observation from report analysis is that Islamic banks have great potential for expansion, given that the demand for Islamic financial transactions is double of what Islamic banks currently offer. If Islamic banks live up to that opportunity, they could deliver more in CSR practices, which is their ultimate goal according to the majority of the interviewees.

Existing literature has presented findings on the CSR of Palestinian corporations in general, but there is no available literature on the CSR practices of Palestinian Islamic banks. This research attempts to fill in the gap by presenting preliminary findings on Palestinian Islamic banks’ CSR practices.

Fish processing by grilling can produce emissions that contain toxic compounds that can have short- and long-term effects on human health. Another study reported that exposure to air pollutants is hematotoxic. The purpose of this paper is to determine the effect of smoke exposure on fish grill results on hematological parameters.

The subjects of this study were 90 grilled fish sellers, with 32 processed food sellers who did not sell grill food as a control. The hematological analysis was performed using the Hematology Analyzers KX300 instrument.

The results showed that the mean value of hematological parameters in the test group was higher than the control group except for the number of lymphocytes and mixed cell parameters.

The content of harmful compounds contained in fish grill smoke can increase hematological value in the blood of exposed individuals, which has the potential for health problems and disease progression.
