Respiratory functions were measured daily by spirometry over four weeks at a summer camp in northwestern New Jersey. Multiple regression analyses indicated that O{sub 3} concentration, cumulative daily O{sub 3} exposure, ambient temperature, and humidity were the most explanatory environmental variables for daily variations in function, and that O{sub 3} concentration had the strongest influence on FVC, PEFR, and MMEf. For FEV1, cumulative daily O{sub 3} exposure and heat stress had greater relative effects. Linear regressions were performed for each child between O{sub 3} concentration and function, and all average slopes were significantly negative (p <0.05) for PVC, FEV1, PEFR and MMEF for all children, and for boys and girls separately. The implications of these short-term effects are unknown. However, the results in these free living children are comparable to those found in chamber studies with comparable exposures.
