introduction earth's atmosphere plays an important role in preventing the temperature decrease. one of the principal factors of environmental pollution and the main source of earth's climate and biodiversity changes is greenhouse gas emissions from various sources, particularly agricultural sector. agriculture sector is considered as a major source of greenhouse gas sequestration, including me...

Background: Combustion of fossil fuels contributes to sulfur dioxide (SO2) emissions. To deal with this issue, the government of Iran has appointed the oil refineries to upgrade their installations and produce high quality fuels. Thus, this study investigated the status of SO2 emissions in Iran and the capability of advanced technologies to control SO2 emissions. Methods: The status of SO2 em...

Vehicular emissions have increased considerably over the years with the increase in traffic. Modern roundabouts can improve traffic flow as well as cut down vehicular emissions and fuel consumption by reducing the vehicle idle time at intersections and thereby creating a positive impact on the environment. The primary focus of this research is to study the impact of modern roundabouts in cuttin...

population growth and increasing industrial and agricultural activities that cause ghg emissions and risk from environmental management is a serious challenge. in this research, the ghg emissions from peanut production as a potential feedstock for biodiesel fuel was investigated. data were collected through interviews with 75 peanut farmers. the cultivated areas were divided into three categori...

Emissions of PAH, nitro-PAHs, and oxy-PAHs from a diesel engine fueled with diesel-biodiesel-ethanol blends need to be controlled reduced, as they are unregulated emissions harmful the environment human health. The objective this work was investigate effect ethanol concentration on when diesel–biodiesel–ethanol blends. Ethanol added biodiesel–diesel Diesel B7 two ternary blends, B7E3 B7E10, 3% ...
