This study in cooperation with the Forest County Potawatomi Community, investigated the effects of ozone exposure on 12 herbaceous species commonly found throughout the Great Lakes region. Ozone concentrations were controlled to test W126 values of (7), (10), and (15). Photosynthesis and plant biomass were compared between the ozone treatments and their respective ambient controls. Our results show that photosynthesis was not negatively impacted by any of the ozone treatments. Only in the W126 (15) treatment was a negative impact to aboveground biomass detected. Our results corroborate that current ozone standards should not cause significant harm to the plants included in this study.
