Abstract: Petroleum refineries around the world have generated the solid wastes during the refining process and stocking of crude oil. The ecology of hydrocarbon degradation by microbial populations in the natural environment is reviewed, emphasizing the physical, chemical, and biological factors that contribute to the biodegradation of petroleum and individual hydrocarbons. The potential of bacterial isolates as hydrocarbon degraders was investigated...........

Abstract: This study presents recent unpublished characterization data on ten tropical biomass species. The experiments carried out to study the events taking place during thermal treatment in both oxidative and non-oxidative environments. In addition, this study also highlights some of the elemental contents of tropical biomass. The correlation between the elemental content of biomass and the thermal behavior was used to indicate the emission pattern. Devolatilization behavior of different tropical samples under steady heating condition also investigated. Thermogravimetric analysis (TGA) technique applied to study the thermo-chemical conversion processes (pyrolysis,...........

Abstract: presence of refugees, regardless to their identity, in any country can lead to environmental costs at the hosting community. The evaluation of Syrian refugee's impact in Lebanon was made by a qualitative descriptive method based on examination of field and available data.According to all observations, air quality is deteriorating from increasing harmful activities like on-road transport, burning solid waste, residential heating, and electricity production. Furthermore, water resources are being overstressed and water quality is affected...............

Abstract: The landfill of Fkih Ben Salah presents a typical example of environmental degradation. It generates a significant amount of waste (85.51 T / J in 2016), and therefore a leachate volume which can reach 3996 T / J (July 2015), these are characterized by a high polluting load; The EC (32.67ms / cm), Turbidity (5190FTU), MES (8,119g / l) and COD (68170mgO2 / l), the treatment of which is essential...............

Abstract: Calcium oxide (CaO) nanoparticle (NP) was synthesized by solution combustion method using urea as fuel. The CaO nanoparticle was characterized by X-ray diffraction (XRD), Scanning Electron Microscope (SEM) analysis and UV-absorption spectral studies. The average crystallite size was found to be ≈36nm and the band gap energy of CaO nanoparticle was 4.9 eV. The toxicity tests were performed on fresh water fish Cyprinus carpio for synthesized CaO NP at different concentrations ranging from 200 to 280 mg/L for 4 days. Bioassays were repeated three times and the data obtained were statistically evaluated using Finney's Probit Analysis. Toxicity test performed revealed that LC50 value for Cyprinus carpio was 234.9mg/L with 95% of confidence limits for 226.819- 242.624mg/L.

Abstract: Mezoneuronbenthamianum (MB) is used traditionally in Nigeria for the treatment of peptic ulcer, diarrhea, and pain. Acute and sub-chronic toxicity studies of the aqueous mixture of the root and leaves of MB were carried out in rodents to evaluate the safety profile. In the acute studies, 7 groups of mice (10/group) were administered with 5-20g/kg of MB orally and 250-2000mg/kg intra-peritoneally (ip). The treated animals were examined for toxic signs and compared with the controls. In the chronic study, MB was administered orally to 20 rats and 20 mice at a daily dose of 320mg/kg.............

Abstract: Male albino rats (Rattus rattus) were divided into four groups of fifteen rats in each group. Two of the studied groups (Group I & II) including the control group (Group I) administered tap water and uncontaminated dried fish collected from a branch of the river Nile, Bahr Yousef at El-Fayoum Governorate. Other studied groups (III & IV) administered highly heavy metals contaminated water and dried fish collected from El-Bats drainage canal, where agricultural and waste municipal of Fayoum Governorate discharged. Moreover, rats in the aforementioned groups administered uncontaminated and contaminated water and dried fish, for eight weeks, supplemented with 300 mg fennel /kg body weight/ day (Second and Fourth groups)..............
