When using E10 (ethanol volume ratio of 10%, v=v) as fuel, the IVOC EF of the tested vehicle was lower than that using commer-cial China standard V fuel. The average IVOC-to-THC (total hydrocarbon) ratios for gasoline-fueled and E10-fueled
Learn MoreRecommendations are made for emission factors (EF's) that can be used to estimate HCN emissions from European FCCU's (for two different operating modes, namely full and partial coke burn) for E-PRTR reporting purposes. An overview of the potential health effects of HCN is given.

Learn MoreAs a result of the rapid growth of international trade, atmospheric pollution from transportation has been more topical than ever, especially in dense hub port-cities. The shipping industry should pay more attention corresponding to its contribution to local atmospheric pollution. This paper supports the application of data collected from the vessel tracking service system with a bottom-up
Learn MoreEmissions of PM, PM-10, and PM-2.5 occur from a number of operations in stone quarrying and processing. A substantial portion of these emissions consists of heavy particles that may settle out within the plant. As in other operations, crushed stone emission sources may be categorized as either process sources or fugitive dust sources.
Learn MoreFeb 18, 2021 · Annual emissions from flight operations can be estimated using the FAA's Emission and dispersion Modeling System (EDMS). EDMS provides data on flight emissions and ground support equipment emission. In flight emissions can also be calculated using the following equation: AE i = EF i x (FFR/1000) x (TIM/60) x NE x 0.002205. Where,
Learn MoreTypes of Lasers There are many types of lasers available for research, medical, industrial, and commercial uses. Lasers are often described by the kind of lasing medium they use - solid state, gas, excimer, dye, or semiconductor. Solid state lasers have lasing material distributed in a solid matrix, e.g., the ruby or neodymium-YAG (yttrium aluminum garnet) lasers. The neodymium-YAG laser emits

Learn MoreThese air pollutants can be either natural (e.g. wildfires) or synthetic (man-made); they may be in the form of gas, liquid or solid. 1. Types of Air Pollutants: An air pollutant is known as a substance in the air that can cause harm to humans and the environment. Pollutants can be in the form of solid particles, liquid droplets, or gases.
Learn MoreAbstract: Compared with purpose-built units, excavator-based harvesters offer many advantages, but they also face one main limitation: a much higher fuel consumption, which also results in higher CO2 emission levels. The fuel efficiency of excavator-based harvesters can be increased by a better interface between the excavator and the harvester

In this study, PM emissions were investigated by DMS500 in terms of particle size distribution function (PSDF), particle number, and mass concentration. The PSDF is expressed as dN /dlogDp, where N is the particle number concentration and Dp is the particle diameter.
