Effect of air filtration systems on asthma: a systematic review of randomized trials.
STUDY OBJECTIVES To systematically review the evidence of randomized trials evaluating the effects of residential air filtration systems on patients with asthma. DATA SOURCES We searched for published and unpublished studies using MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Collaboration. We reviewed all reference lists for additional articles of re...
متن کاملAsthma and air pollution
During the last decades research all over the world has highlighted the deleterious effects of pollution on respiratory health of adults and children. Nevertheless, air pollution still represents a significant threat to health. Children are more sensitive than adults to pollutants for several factors: increased respiration relative to body size; physiologic immaturity of respiratory and immunol...
متن کاملPilot study of high-performance air filtration for classroom applications.
UNLABELLED A study was conducted to investigate the effectiveness of three air purification systems in reducing the exposure of children to air contaminants inside nine classrooms of three Southern California schools. Continuous and integrated measurements were conducted to monitor the indoor and outdoor concentrations of ultrafine particles (UFPs), fine and coarse particulate matter (PM2.5 and...
متن کاملElectrospun Polyurethane/β-Cyclodextrin Composite Membranes for Aerosol Filtration and Adsorption of Volatile Organic Compounds from the Air
Introduction: Electrospun nanomembranes have been used for effective air filtration due to their potential for active surface modification. This study aims to synthesize polyurethane (PU) nanofiber membrane incorporated with different amounts of β-cyclodextrin (β-CD) to capture volatile organic compounds (VOCs) along with aerosol filtration from the air. Material and Methods: First, PU was sy...
متن کاملAir pollution, epigenetics, and asthma
Exposure to traffic-related air pollution (TRAP) has been implicated in asthma development, persistence, and exacerbation. This exposure is highly significant as large segments of the global population resides in zones that are most impacted by TRAP and schools are often located in high TRAP exposure areas. Recent findings shed new light on the epigenetic mechanisms by which exposure to traffic...
