A Lagrangian Long Range Transport Model with Atmospheric Boundary Layer Chemistry

Abstract: The present paper reports on the combination of a chemical model for the gas phase chemistry of the atmospheric boundary layer, with a Lagrangian model for the long-range transport of air pollutants. The resulting combined chemistry/transport model is applied in a case study where polluted air is transported toward Scandinavia. Calculations show good agreement with measured ozone concentrations, and strongly suggest that the measured ozone concentrations cannot be due to Scandinavian precursor emissions alone. In order to carry out the case study, the emissions of NOx and hydrocarbons were estimated for the different European countries. Such estimates will necessarily be uncertain. However, the degree of consistency obtained between calculations and measurements indicate that the estimated emissions by and large reflect reality. Various tests were carried out to investigate the sensitivity of the predicted ozone concentrations with respect to parameters such as advection wind, deposition velocity...

Chapter 2 Measurement of Thermal Balance of Man

Abstract: Publisher Summary The thermal environment of man begins at the skin surface and extends outward to the surrounding media, which consist of the air that he breathes; the clothing that he wears; man-made sources of heat and cold necessary for health and comfort; heat, cold, and humidity caused by weather; and exposure to solar radiation All these factors are characterized by temperature, or they in some way affect the heat transfer from the skin surface by radiation, convection, conduction, or evaporation Heat balance equations describing human heat exchange by radiation, convection, evaporation, and conduction from the skin surface with the thermal environment are discussed in the chapter The environmental variables in the basic heat balance equation that must be measured are the ambient air temperature, the mean radiant temperature or effective radiant field, the ambient water vapor pressure or humidity, air movement as it affects the convective and evaporative heat loss, and clothing insulation The physiological variables in the heat balance equation are skin temperature, skin wettedness, mean body temperature, metabolic energy consumption, and the rate of external work

Impact of climate change on the discharge of the river rhine

Abstract: Climate change influences the water balance of drainage basins in several ways In a project of the International Commission for the Hydrology of the Rhine basin the possible consequences for the discharge regime of the Rhine are investigated In the first phase of this project detailed models have been developed and applied for selected sub-basins and a simple water balance model has been developed for the whole Rhine basin Results are presented for climate scenarios assuming an increase in temperature of about 3°C and an increase in annual precipitation The consequences of such a climate change are largest in the Alpine part of the Rhine basin, and are also considerable in other parts of the basin and for the basin as a whole In general the Rhine changes towards a rain-fed river The winter discharge increases, which can have consequences for safety, and summer discharge decreases with consequences for shipping, industry, agriculture and ecology

Electrochemical oxidation of organic pollutants for wastewater treatment

Abstract: The aim was to examine the anodic oxidn. of some benzene derivs. (model org. pollutants) at Pt and DSA (dimensionally stable anodes) type anodes to elucidate the possibilities of the electrochem. method and to elucidate the mechanism of the reaction.

Validation of landfill gas formation models

Abstract: Three models for landfill gas formation were validated and the model parameters were estimated for Dutch landfills. Landfill gas formation could be well described, using a first-order and a multi-phase model. The half time of biodegradation was estimated to be about 7 years; ultimately 60% of the organic carbon is estimated to be converted into landfill gas.
