Abstract

Ogawa passive O-3 samplers were used in a 13-week study (June 1-September 1, 1999) involving 11 forested and mountaintop sites in north-central Pennsylvania. Four of the sites were collocated with TECO model 49 O-3 analyzers. A significant correlation (p < 0.0001) was found for 24-hr average weeklyO-3 concentrations between the two methodologies at the four sites with collocated monitors. As expected, there were positive relationships between increasing elevation of the sites and increasing O-3 concentrations. No O-3 exposure patterns were found on a west-to-east or south-to-north basis; however, the area known for lower O-3 exposures within a smaller subsection ofthe study area showed consistently lower O-3 exposures. Preliminary results regarding relationships of symptom responses within O-3-sensitive bioindicators are also presented with black cherry (Primus serotina, Ehrh.) and common milkweed (Ascleplas syriaca, L.) showing clear evidence of increasing injury with increasing O-3 exposures. Due to the extremely dry conditions encountered in north-central Pennsylvania during the 1999 growing season, O-3-induced symptoms were sporadic and quite delayed until late-season rains during the latter portion of the observation period.
