Title Moderate increases in ambient PM2.5 and ozone are associated with lung function decreases in beach lifeguards
Bibliographic information Feb. 2008, Vol.50, No.2, p.202-211. Illus. 40 ref.
Abstract The objective of this study was to determine whether exposure to pollutants would adversely affect the lung function of healthy athletes. Pulmonary function was recorded on beach lifeguards at three different times during the day. Daily and average peak pollutant levels were also measured. Data were subjected to statistical evaluation. Afternoon forced vital capacity (FVC) and one-second forced expired volume (FEV1) decreased significantly compared with morning values and decreased with increasing fine particulates (PM2.5). The FEV1/FVC ratio decreased with increasing ozone (O3) levels. The deleterious effect of PM2.5 and O3 were transient and occurred at pollutant levels far below national standards. At low levels of exposure, PM2.5 was associated with reduced lung volumes, while increasing O3 levels were associated with airway obstruction.
