Four major factories (Petroleum Refineries Company, Detergents Plant, Thermal Power Plant, and Gaseous Power Plant) are located to the north of Baiji City. They release pollutants in form of gases, liquids and solids; they find their way to the surrounding environment. To assess the environmental pollution of the area, 18 samples of surface soil distributed around the industrial establishments were collected and analyzed to determine the concentration of polycyclic aromatic hydrocarbons (PAH) components which are often targets in the environmental checking. Identification and quantification of the 16 PAHs components was accomplished using High Performance Liquid Chromatography (HPLC) had a model Shimadzu LC-10 AVP. The total concentrations of 16 PAHs were ranged from (94.9) to (416.3) μg/kg with an average value of (217.5) μg/kg. The most abundant PAHs was Fluorene followed by Acenaphthylene, Naphthalene, Chrysene, Phenanthrene, Benzo(b)fluora-nthene, Fluoranthene, Benzo(a)anthracene, Benzo(a)pyrene, Benzo(g,h,i)perylene, Dibenzo(a,h)anthracene, Indeno(1,2,3-cd) pyrene, Pyrene, Acenaphthene, Anthracene, and Benzo(k)fluoranthene.
Seven possible carcinogenic PAHs (Σ7c-PAHs) accounted 38.9 % to the total PAHs. The petroleum combustion and biomass combustion were the main sources of PAHs in the surface soil. The mean values of cancer risk levels for children via ingestion, dermal contact, and inhalation were (6.02*10-7), (7.51*10-7) and (5.91*10-12) respectively, suggesting no potential health hazards, while these for adults were (1.78*10-6), (3.16*10-6) and (1.40*10-10) respectively, implying potential health risks via ingestion and dermal contact, but not via inhalation exposure. The total value of ILCRing+drm+inh for children and adults via three exposure pathways were (2.43*10-5) and (8.90*10-5) respectively, indicating potential health risks.

Background: Chronic hyperplastic candidiasis is the least common type of oral candidiasis. The diagnosis, long-term treatment, and prognosis of this potentially malignant oral condition are still currently unclear. Objective: the aim of this study is to analyze the demographic features and clinical characteristics of oral chronic hyperplastic candidiasis. Materials and Methods: A retrospective analysis was performed on blocks and case sheets of patients who were diagnosed with chronic hyperplastic candidiasis in the archives of Oral and Maxillofacial Pathology at the College of Dentistry/University of Baghdad. Demographic and clinical characteristics were analyzed. Results: twenty-one cases with chronic hyperplastic candidiasis were coll

The Asphalt cement is produced as a by-product from the oil industry; the asphalt must practice further processing to control the percentage of its different ingredients so that it will be suitable for paving process. The objective of this work is to prepare different types of modified Asphalt cement using locally available additives, and subjecting the prepared modified Asphalt cement to testing procedures usually adopted for Asphalt cement, and compare the test results with the specification requirements for the modified Asphalt cement to fulfill the paving process requirements. An attempt was made to prepare the modified Asphalt cement for pavement construction in the laboratory by digesting each of the two penetration grade Asphalt c
