When inhaled, @entity3878 is a highly irritating gas that can damage larger airways as well as distal lung structure. We examined the short-term respiratory effects of acute @entity3878 inhalation during a swimming pool accident. On October 22, 1998, an emission of @entity3878 vapours occurred in the chlorinating maintenance procedures room of a recreational center in Rome. A total of 282 subjects (134 @entity1 ) inhaled @entity5836 and @entity8830 . Most @entity1 received bronchodilators and @entity821 at the emergency room; five @entity1 were hospitalised. A telephone follow-up was taken on 260 (92.2%) subjects to obtain information about duration of exposure (less than 3 minutes, 3-5 minutes, more than 5 minutes), intensity of exposure (not at all/a little, a fair amount, a lot), and acute @entity1576 . A total of 236 (90.7% of the target) individuals underwent clinical examinations, which took place 15-30 days after the accident. Lung function was measured in 184 @entity1 (82 @entity1 ) after 15-30 days. A multiple linear regression was run to test the association between @entity3878 exposure and lung function, separately in adults and in @entity1 . Acute @entity1576 occurred among 66.7% adults and 71.6% @entity1 . The incidence rates were highest among those who had chronic @entity1576 and had a longer duration of exposure. In about 30% of the subjects, @entity1576 persisted 15-30 days after the accident. Lung function levels were reduced among those who reported high intensity of exposure in comparison to those who reported low exposure, both in @entity1 and in adults (forced expiratory volume in one second, FEV1, ml differences: -109 (CI 95%: -310, 93) and -275 (CI 95%: -510, -40). Given high prevalence of potential exposed @entity1 , findings from this study should alert public health authority about the possible clinical consequences.
