The Federal Institute for Materials Research and Testing and the company AirRobot GmbH & Co. KG cooperate to develop a flying remote-controlled measuring system. The system is capable of operating in a variety of scenarios of gas emission, e.g. exhaust gas from a chimney, flue gas in case of a fire, gas emission in case of an accident of chemical or hazardous goods or in case of a terrorist act...

This contribution deals with NO and N2O emissions during autotrophic nitrogen removal in a granular sludge reactor. Two possible model scenarios describing this emission by ammonium- oxidizing biomass have been compared in a simulation study of a granular sludge reactor for one-stage partial nitritation--Anammox. No significant difference between these two scenarios was noticed. The influence o...

The Technical University of Madrid (UPM) is currently studying the different alternatives to reduce air pollution in Spain. The policy design and decision-making for improving Air Quality are based on emission projections up to 2020 under several scenarios. The following step is to evaluate the impact of these scenarios using an Air Quality Model. The US EPA CMAQ modeling system has been select...

One problem in international climate policy is the refusal of large developing countries to accept emission reduction targets. Brazil, China and India together account for about 20% of today’s CO2 emissions. We analyse the case in which there is no international agreement on emission reduction targets, but countries do have domestic targets, and trade permits across borders. We contrast two sce...

Atmospheric mercury emission scenarios from artisanal and small-scale gold mining for 56 tropical subtropical countries have been elaborated assessed their comparative significance. A multi-step quantitative method that yields narrow robust confidence intervals estimates was employed. Firstly, data on production different years, the ratio of used in amalgamation processes, ancillary input param...

flood is one of the most calamitous natural disasters that causes extensive property and life damages across theworld. it however, could be a blessing due to its special natural water resources recharging value. by simulating themagnitude of probable floods considering the anthropogenic and natural effects and implementing contingency plans,their damages could be reduced. in this paper, the gen...

Current regulation aimed at reducing inorganic atmospheric fine particulate matter (PM2.5) is focused on reductions in sulfur dioxide (SO2) and oxides of nitrogen (NO(x) = NO + NO2); however, controls on these pollutants are likely to increase in cost and decrease in effectiveness in the future. A supplementary strategy is reduction in ammonia (NH3) emissions, yet an evaluation of controls on a...

International political debate on how climate change should be mitigated has grown stronger, and one key issue has been burden sharing, i.e. the question of how much each nation should be allowed to emit greenhouse gases. This Thesis examines the outcomes of emission reductions using the TIMES energy system model in four SRES scenarios, proposes a multicriteria approach for evaluating economic ...

The dynamic IO model DIMITRI will be used for explorations of long-term scenarios on technology and demand. The model describes at a sectoral level the relationships between consumption, production and emissions. Technology per sector is described by the inputs from other sectors (represented by IO coefficients) and capital, labour and emission coefficients. Since these coefficients are not sta...

background: the air dispersion models are widely used to evaluate and predict the pollutants emissions from air pollution sources such as incinerators. this study attempts to predict the heavy metal pollutants dispersion emitted by an incineration plant impacting its surrounding area. methods: several scenarios of emission rates coupled with the meteorological conditions were investigated using...
