Urban meteorology and pollution are characterised by a number of atmospheric parameters and their evolution in time, which all have specific problems as to their monitoring, representativeness, parameterisation and modelling compared to rural situations. The main goal of the Action COST-715 (1998-2004) was to provide the best guidance on how meteorology may be included in pollution calculations...
Recently, indoor air quality has attracted the attention of policymakers and researchers as a critical issue like that of external air pollution. Indoor air quality is more important as people spend time longer indoors than outdoors. Indoor environments are closed compared to external environments providing less opportunity for the pollutants to dilute. The emissions contain many substances tha...
the most important environmental pollutant in steel industry is air pollution due to the process of its products. optimise sitting for this industry, in a great extend will prevent pollutants and emissions. khorasan steel company is located near some populous villages and three rivers. it is necessary to perform an investigation for providing abatement and control of air pollution, in time of p...
In this paper, we assess the status of the air quality in the Lake Baikal region which is strongly influenced by the presence of anthropogenic pollution sources. We combined the local data, with global databases, remote sensing imagery and modelling tools. This approach allows to inventorise the air-polluting sources and to quantify the air-quality concentration levels in the Lake Baikal region...
of gaseous pollutants on paintings installed in microclimate frames (mc-frames), and some examples of modelling results, is presented. The model can be used to study how basic design properties of microclimate frames, such as their air exchange rate, their volume and/or the inclusion of absorbers can affect the pollution fluxes to paintings inside the frames. The modelling indicated that a magn...
Estimating the future state of air quality associated with transport policies and infrastructure investments is key to the development of meaningful transportation and planning decisions. This paper describes the design of an integrated transportation and air quality modelling framework capable of simulating traffic emissions and air pollution at a refined spatio-temporal scale. For this purpos...
background: measuring and monitoring of air pollutants are one of environmental and all' pollution controls tools. due to lack of widespread data in iran, this study was performed to estimate the trends of major pollutant emissions to atmosphere in the uk from 1980 to 1996. methods: this investigation is a retrospective study that the data were collected from the departments of environment, tra...
the east mediterranean region suffers from high levels of air pollution which has a negative impact on pregnancy outcomes. this work systematically reviews the epidemiological evidence on maternal exposure to air pollution and adverse pregnancy outcomes in the region. relevant papers and reports published between 2000 and 2014 were searched. combinations of search terms including countries, exp...
background : health professionals face the adverse health effects of climate change and air pollution in their practices. this review underscores the effects of these environmental factors on maternal and children’s health, as the most vulnerable groups to climate change and air pollution. methods : we reviewed electronic databases for a search of the literature to find relevant studies publish...
In a study of signs and symptoms of lead intoxication in workers in lead processing industries in the Netherlands, use has been made of the apparatus described by Donath (1956) for semiquantitative determination of coproporphyrin excretion. The significance of this method in the screening of exposed groups of workers has been investigated. The method proved to be a valuable tool in the preventi...
