The study objectives of this research were 1 To determine if the pollution levels alone were responsible for the observed growth suppressions in trees growing at Radford Army Ammunition Plant RAAP 2 To screen several full-sib families of loblolly pine and half-sib families of American sycamore for tolerance or sensitivity to O3, SO2, and NO2 3 To identify and quantify the effects to loblolly pine and sycamore of long-term low-level exposures to O3, SO2, and NO2 in combination 4 To demonstrate the success or failure of the abatement programs now being initiated at the RAAP, with loblolly pine andor American sycamore as bioindicators and 5 To contribute to the field of air pollution effects on plants an understanding of the growth impact of pollutant interactions.
