摘要

It is well known that airborne pollen can affect lung function and general well-being. This is particularly true for individuals predisposed to respiratory complications (for example sufferers from hay fever and asthma). Globally, there is evidence that asthma incidence is increasing in children over 2 years of age, and, within the UK, the south-east of England has the highest incidence for all ages in the population. Variations in lung function of school children (measured as peak expiratory volume) with associated changes in airborne pollen and pollution loads at two contrasting sites (one urban, the other rural) within the Medway Towns in south-east England were measured during the pollen season in 1998. Children of similar ages and social backgrounds participated in the studies, and account was taken of children with known respiratory problems. Pollen, pollution and weather data were collected at each site. A picture has been obtained of how changes in local and regional aeroallergen levels, as well as other environmental factors, effect public health in this region of England. Children at the urban site produced consistently better average lung function results, although more pollen was caught there. At the rural site there was generally no relationship between pollen counts and lung function. As expected, lung function was lower on anticyclonic days when there was less mixing in the air. There is strong evidence that episodes of air pollution were more important in promoting reduced peak expiratory flows than specific aeroallergen levels alone. Whilst this requires further investigation, it confirms that attributing changes in lung function solely to pollen levels may sometimes be misleading.
