TL;DR: In this article, the relationship between indoor and outdoor airborne particles was investigated for 16 residential houses located in a suburban area of Brisbane, Australia, using simultaneous and non-simultaneous measurement methods designed for the purpose of the study.

TL;DR: The aim of this paper was to develop, calibrate and test a simple model for 'on-road' measurements of traffic emission factors as part of a major program focussed on the assessment of traffic contribution to fine and ultrafine emissions to the whole air shed and to local areas in south-east Queensland, Australia.

TL;DR: Estimates of the magnitudes of these potential effects demonstrate that none of these mechanisms alone can be responsible for the significantly higher total ETS deposition observed in the experiments, suggesting that a combination of all these mechanisms may be necessary to reconcile experimental and theoretical Ets deposition data.
Abstract: Total deposition of environmental tobacco smoke (ETS) particles was measured in a group of 15 nonsmokers who inhaled ETS of count median diameter of 0.2 μm and geometric standard deviation of 1.6. ...

TL;DR: In this paper, the author describes the feeling of distance and space when flying across the oceans separating the continents of the Southern Hemisphere and the effect of human problems and human actions on a grand scale.

TL;DR: In this article, the authors present an extension of the model to include the effects of humidity and temperature, as well as topographical aspects, on the concentrations measured, taking into account wind is the only removal mechanism of the emitted pollutants.
Abstract: Motor vehicle emission factors for application in traffic/transport models are often estimated indirectly, through measurements of pollutant concentrations in the close vicinity of a road link. Such an approach provides insight into total vehicle fleet emissions on the link. However, estimation of emission factors form the measured concentration raise a set of complex issues. The concentrations dement not only on the emission factors, but also to a large degree on meteorological factors as well as on the topography of the land. Using the number/mass balance mode, a theoretical relationship was developed that allows for calculation of emission factors from the concentrations measured at a specific point above the road, taking into account wind is the only removal mechanism of the emitted pollutants. By using this model, average emission factors for all vehicles on the road can be estimated and then used to arrive at emission factors for individual types of vehicles, given a known fleet composition. This paper presents an extension of the model to include the effects of humidity and temperature, as well as topographical aspects, on the concentrations measured.
