Fossil fuels are the most imperative parameters to flourish the every sphere of modern civilization including industrial development, transportation, power generation and easing the accomplishment of works. The rapid increase in usage of fossil fuel has unavoidable deleterious effect on environment. The international consciousness for environment protection is growing and ever more strict emiss...

The pharmacokinetic concepts of bioavailability and biotransformation are introduced into the assessment of public health risk from experimental data concerning the emissions of potentially mutagenic and carcinogenic substances from motor vehicles. The inappropriateness of an automatic application in the risk assessment process of analytical or experimental results, obtained with extracts and p...

Used cooking oil (UCO) is a hydrocarbon that causes significant environmental pollution globally. Oil difficult pollutant to remove from the environment due its hydrophobic nature. Bioremediation preferred over chemical and physical remediation approaches as it more economical environmentally friendly. Hence, search for microbe with outstanding degrading capability imperative nature of hydrocar...

Diesel-powered agricultural machinery (AM) is a significant contributor to air pollutant emissions, including nitrogen oxides (NOx) and particulate matter (PM). However, the fuel consumption emissions from AM remain poorly quantified in many countries due lack of accurate activity data factors. In this study, emission were estimated using survey factors literature. A case study was conducted co...

This research evaluated the hydrocarbon emission characteristics during pyrolysis of four carbonaceous additives that can be used in green sand foundries. These included a highly volatile bituminous coal, anthracite, lignite and cellulose. The samples were flash pyrolyzed in a Curie-point pyrolyzer at 920 C with a heating rate of about 3000 C/sec. This simulated the fast heating conditions that...

Exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (dioxin) results in a broad spectrum of toxic effects. Most, if not all, of these responses are dependent upon the binding of dioxin to the aryl hydrocarbon receptor. Given their common roles in chemically induced toxicity, we asked whether interleukin 1 (IL1)-like cytokines play a role in acute aspects of the dioxin response. To test this idea, w...

Oil pollution is a worldwide threat to the environment and the remediation of oil-contaminated soils, sediments and water is a major challenge for environmental research. Bioremediation is a useful method for soil remediation, if pollutant concentrations are moderate and non-biological techniques are not economical. The bioremediation consists strategy of actively aerating the soils and adding ...

lurestan province is petroliferous area. the reserved oil are in ilam and sarvak  (cretaceous ) and kangan ( lower triassic ) and dalan (permian) formations. the lurestan area had high exploration activity but contribution of source rocks in hydrocarbon accumulations isn’t clear. in this paper essential elements and process of hydrocarbon accumulation are introduced. candidate  source  rocks ar...

A cloned cell line derived from normal hamster tracheal epithelium has been characterized with respect to its response to the environmental pollutant and carcinogen benzo(a)pyrene [B(a)P]. These cells metabolize B(a)P to ultimate reactive forms as assayed by alkylation of DNA. Alkylation with radiotracer amounts of B(a)P was maximum at 8 hr, at which time 70% of the applied hydrocarbon had been...

Chronic exposure to 2,3,7,8-tetrachlorodibeno-p-dioxin (TCDD) and related polyhalogenated organic pollutants occurs as a consequence of modern life. Exploring the cellular basis for their action is anticipated to help understand the risk they pose and improve the foundation for their regulation. A basis for the striking change in human keratinocyte colony morphology due to TCDD exposure has bee...
