Estimating observations for additional quality control of air quality measurements blad 4 van 41 Measurement validation by observation predictions

background: although lebanon is a highly polluted country, so far no study has specifically been designed to assess the association between outdoor air pollution and chronic bronchitis in this country. objective: to assess the association between exposure to outdoor air pollution and chronic bronchitis in lebanon. methods: a pilot case-control study was conducted in two tertiary care hospitals....

This paper examines the performance of five different air terminal devices for personalized ventilation in relation to the quality of air inhaled by a breathing thermal manikin in a climate chamber. The personalized air was supplied either isothermally or non-isothermally (6°C cooler than the room air) at flow rates ranging from less that 5 L/s up to 23 L/s. The air quality assessment was based...

air quality is a topic of crucial importance, because air pollution is one of the most important pollution problems in the world. in particular, predicting or detecting a future extreme air pollution episode or predicting the violation of an air quality standard, is of crucial interest in the field of pollution control. there have been a variety of attempts to reach this purpose both from the p...

the centralization of human activities is associated with different pollutants which enter into environment easily and cause the urban environment more vulnerable. regarding the importance of air pollution issue for tehran metropolis, many plans and regulations have been developed. however, most of them failed to decline the pollution. the purpose of this study was to pathologically analyze air...

In this study, the empirical results obtained from two experiments to measure the health and aesthetic benefits of air pollution control in the South Coast Air Basin of southern California are reported. Each experiment involved the same six neighborhood pairs, where the pairings were made on the basis of similarities in housing characteristics, socioeconomic factors, distances to beaches and se...

The object of this research is the new concept original universal system for air quality and energy control in laboratory conditions (wet scrubbing system) based on ?clean in/out? principle. Namely, process involves a partial or complete exchange recirculated treated air. From aspect water, as pure medium, characterized by broad application open, semi-open, closed treatment systems: primarily b...
