An outdoor experiment was set up to investigate the effects of used lubricating oil (5 L/m2) on Aegiceras corniculatum Blanco. and Avicennia marina (Forsk) Vierh., two salt-excreting mangroves. A. marina was more sensitive to used lubricating oil than A. corniculatum and canopy-oiling resulted in more direct physical damage and stronger lethal effects than base-oiling. When treated with canopy-...

Heavy crude oil can be upgraded to lighter oil using several techniques. However, current methods usually require high temperatures, long reaction duration, and cause serious environmental pollution. This study shows that by using carbon nanocatalysts, heavy crude oil can be efficiently upgraded to lighter oil at a relatively low temperature of about 150 °C. The temperature of crude oil was inc...

In this paper, a review of Synthetic Aperture Radar (SAR)-based techniques, for oil slick at sea observation is proposed, focusing in particular on polarimetric approaches. In fact, marine oil pollution monitoring is a topic of great applicative and scientific relevance and in such a context, among all remote sensing sensors, SAR represents a fundamental tool due to its almost all-weather and a...

in this paper, the potential of polarimetric sar data using target decomposition features to detect oil pollutions are evaluated. for this purpose, the values of power, phase and magnitude of all of the polarization channels (hh, vv, hv and vh) and decomposition features i.e. freeman, yamaguchi, vanzyl and krogager are computed. then, to detect oil pollutions, different combinations of these fe...

there are many potential sources of stormwater pollutants in urban areas; one of these sources is gas stations, which are numerous and spread city-wide. a study was conducted to evaluate the water quality of runoff from gas stations in the city of tijuana, mexico. pollutant loads in runoff from gas stations in the study area were higher than in other published studies. the estimated loads from ...

(1) A few shipping accidents have caused spectacular local threats to the environment. (2) Leaks in offshore oil well drilling operations have received widespread news coverage. (3) A rising demand for petroleum products throughout the world complicated by political considerations has produced a corresponding expansion in tanker shipping operations and in offshore oil operations, both of which ...

In this article, the Environmental pollution in Iraq was studied by using the remote sensing techniques for the period (2010-2014). In general, the environmental pollution can be divided into three major parts: Air, Water, and soil pollutions. To overcome the problem, multi-satellite images with different resolution and bands at different dates were used to detect and quantize the source of pol...

In Estonia there is the largest industrially-used oil-shale basin in the world. This review addresses the environmental hazard of the waste streams of oilshale industry via solid wasteand water-path, mainly focusing on ecotoxicological risk due to open semicoke deposition inducing hazard to surrounding soils and groundwater. This is the first comprehensive ecotoxicological review of available d...
