This chapter describes how estimates of air pollution emissions are transformed into ambient concentration of pollution, further translated into exposure and health impacts on a population, and finally expressed in damages. Different trade and environmental policy menus lead to different levels of pollution emissions and income. For each menu the emissions levels translate into specific mortali...

Experiments were performed to investigate the effects of sulfur dioxide (O-10 ppm) and chlorine (O-15 ppm) on ozone and nitric oxide concentrations in irradiated mixtures of nitrogen dioxide (1-5 ppm) and air. The mixtures were irradiated by ultraviolet fluorescent lamps while flowing at a steady speed through a 9 m long, 15.2 cm i.d. Pyrex tube. The presence of sulfur dioxide produced no measu...

In recent years more and more focus has been placed on the environmental aspects of ships, because of the great attention to exhaust gas emissions from ships including CO2, a leading contributor to Green House Gasses (GHG) emissions, due to their negative effect on global warming. Maritime transport has clear environmental advantages: it expends relatively little energy and its infrastructure r...

The aim of this study was to investigate the association between daily changes in respiratory health and air pollution in 489 adults, aged 50-70 yrs, with and without chronic respiratory symptoms, living in urban and nonurban areas in the Netherlands. Subjects were selected from the general population with a screening questionnaire. During three consecutive winters starting in 1992/1993, peak e...

Drying of Matricaria recutita flower was investigated experimentally in a VibroFluidized Bed Dryer (VFBD). The aim of the present work was to optimize the best operating conditions for the drying of Matricaria recutita flower in the VFBD based on experimental design techniques. Response Surface Methodology (RSM) and Central Composite Design (CCD) based on 4-variable with 5-level have been e...

Background: Adverse pregnancy outcomes (low birth weight, prematurity and intrauterine growth retardation) are associated with exposure to urban air pollution. Experimental data have also shown that such exposure elicits adverse reproductive outcomes. We examined association between spontaneous abortion of the first trimester of pregnancy and ambient concentrations of Ozone, Nirogen Dioxide and...

not flow in blocks). For example, if malfunction of the inspiratory valve results in decreased resistance, it is conceivable that more than half of the expiratory gases might enter the inspiratory limb. This, in conjunction with the gas mixing between carbon dioxide–containing expiratory gases and carbon dioxide–free fresh gases may cause the final portion of the inspiratory tidal volume to con...
