Urban trees, air quality, and asthma: An interdisciplinary review

Indoor Air Quality and Asthma

Numerous contaminants in indoor air and their potential to cause or exacerbate asthma continue to be a subject of public health concern. Many agents are causally associated with or can exacerbate asthma, particularly in children. For formaldehyde, an established respiratory irritant based on numerous studies, the evidence for an association with asthma is still considered only limited or sugges...

Cool Surfaces and Shade Trees to Reduce Energy Use and Improve Air Quality in Urban Areas

Elevated summertime temperatures in urban ‘heat islands’ increase cooling-energy use and accelerate the formation of urban smog. Except in the city’s core areas, summer heat islands are created mainly by the lack of vegetation and by the high solar radiation absorptance by urban surfaces. Analysis of temperature trends for the last 100 years in several large U.S. cities indicate that, since | 1...

Air Quality and Pediatric Asthma-Related Emergencies

tracheal injection of ovalbumin-fluorescein isothiocyanate (FITC) or ovalbumin and were killed at varying time points thereafter depending on the aspect of DC function being studied (migration, maturation, or T-cell activation). Lung cells were isolated, and the numbers of DCs were determined in exposed and unexposed mice by flow cytometry. Migration of lung DCs to thoracic lymph nodes (TLNs) w...
