Of the outdoor air pollutants regulated by the Clean Air Act of 1970 (and recently revised in 1990), ozone has been the one pollutant most difficult to control within the federal standards. The known human health effects are all on the respiratory system. At concentrations of ozone which occur during summer air-pollution episodes in many urban metropolitan areas of the United States, a portion ...

backgrounds and aims: ammonia removal from air to prevent severe damage to the environment and living organisms is very important. biofiltration is an efficient, easy, cost-effective, and environmentally friendly process for degradation of ammonia from waste air. the aim of this study is to investigate the efficiency of biological filtration using a compost and scallop bed for ammonia removal. ...

the aim of this research paper is the introduction of a novel mathematical approach to improvethe accuracy of the results of air pollution dispersion models based on the calibration of input backgroundconcentrations. using the dunkirk area of the city of nottingham in the uk as a case study, an air pollutionmodel in adms-roads was created for developing the mathematical approach. the iterative ...

Health risks from poor malaria control, unsafe water, and indoor air pollution are responsible for an important share of the global disease burden-and they can be addressed by efficacious household health technologies that have existed for decades. However, coverage rates of these products among populations at risk remain disappointingly low. We conducted a review of the medical and public heal...

Introduction: Although epidemiological studies have reported an association between smoking and increases in tuberculosis the , relationship between indoor air pollution and risk of tuberculosis is not fully understood. A limited number of studies have suggested that smoking and indoor air pollution may play a role in the pathogenesis of tuberculosis. In this study, we investigated the effect o...

OBJECTIVE Characterising exposure to indoor air pollution arising from solid-fuel use in extremely poor Colombian households. METHODS Data from the September 2012 survey by Red Unidos (literally United Network, the Colombian government's official instrument for identifying extremely poor households: n=1.3 million households and >5 million people) was used for two logistic regression models: f...

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...

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...

Asthma is common in children worldwide, although its prevalence varies substantially by location. The prevalence of wheeze over a 12-month period ranged from 2.1% to 32.2% in the older age group (13–14 years) and 4.1% to 32.1% in the younger age group (6–7 years) [1]. There is a positive association between current symptoms of asthma in younger and older children with gross national income [2],...

OBJECTIVE To evaluate indoor air pollution in hospitality venues in Argentina. MATERIAL AND METHODS PM₂.₅ levels were measured in a convenience sample of venues in 15 cities with different legislative contexts following a protocol developed by Roswell Park Cancer Institute. RESULTS 554 samples were collected. Across all 5 smoke free cities the mean PM₂.₅ level was lower during daytime vs. e...
