Residential Proximity Land Use Characteristics and Exhaled Volatile Organic Compounds' Impact on Pulmonary Function in Asthmatic Children.

ABSTRACT:

Background

Urban air pollution adversely affects children's respiratory systems, but the impact of volatile organic compounds (VOCs) on children's pulmonary function remains unclear. This study aims to identify exhaled VOCs linked to land use characteristics and reduced pulmonary function in asthmatic children, as well as to explore environmental thresholds influencing VOC exposure levels.

Methods

We enrolled 97 asthmatic children, aged 7 to 20, from Changhua County, Taiwan, and collected personal and residential data, collected exhaled VOC samples, and conducted pulmonary function tests. Land use characteristics were derived from the children's residential addresses. This study used two models to explore the relationships between land use, VOC levels, and pulmonary function
