BACKGROUND Industrial air pollution is a growing challenge to humane health, especially in developing countries, where there is no systematic monitoring of air pollution. Given the importance of the availability of valid information on population exposure to air pollutants, it is important to design an optimal Air Quality Monitoring Network (AQMN) for assessing population exposure to air pollut...
The air pollutions from combustion flue gas and industrial gases became worse and cause the environmental problem. It is difficult for the conventional methods such as selective catalytic reduction method and lime-gypsum method to treat exhaust gases energy efficiently and inexpensively. Its energy efficiency and its initial and running costs are still in negative situation for the backward nat...
In a rural population-based cohort study of approximately 500 Gambian children under five years old followed for one year, incidence of acute lower respiratory infections (ALR) was related to various risk factors including parental smoking and regular carriage on the mother's back while cooking, a proxy measure for exposure to smoke from cooking fires. Two statistical analyses using a 'child-we...
Human exposure to air pollution in many studies is represented by ambient concentrations from space-time kriging of observed values. Space-time kriging techniques based on a limited number of ambient monitors may fail to capture the concentration from local sources. Further, because people spend more time indoors, using ambient concentration to represent exposure may cause error. To quantify th...
Increasing attention has been focused on the health effects of urban transport in recent years. This report highlights the framework in which integrated assessment of the effects of urban transport on health can be carried out. The discussion is based on the results of a research project called HEARTS (health effects and risks of transport systems) conducted as part of the Fifth Framework Progr...
I n the Western world the role of air pollution in the initiation of respiratory disease in children is contentious [1]. There is good evidence that air pollution can trigger symptoms in susceptible children but its contribution to the pathogenesis of childhood respiratory disorders, such as asthma, remains unclear. There has been considerable interest in traffic-related pollutants and studies ...
OBJECTIVES In Bangladesh, second-hand smoke (SHS) is recognised as a principal source of indoor air pollution and a major public health problem. However, we know little about the extent to which people are aware of the risks of second-hand smoking, or restrict smoking indoors or in the presence of children. We report findings of a community survey exploring these questions. DESIGN AND SETTING...
Air Force (AF)-certified registered nurse anesthetists (CRNAs) play an important role in the support of the global war on terror. The purpose of the investigation was to use an AF CRNA-specific modification of the Readiness Estimate and Deployability Index Revised for AF Nurses to assess readiness for deployment. Dimensions included clinical competency, operational competency, soldier/survival ...
BACKGROUND AND OBJECTIVES In many places in Europe, the ambient air pollution exceeds the levels considered to be safe for health. The objective of the paper is to review and summarise the methods of assessment of its impact on health, and to indicate the contributions of various research disciplines, particularly environmental epidemiology. METHODS The framework for assessment of impact is b...
