| Abstract | Total oxidants and associated oxidant injury to white pine were determined at three rural sites in Virginia: (1) Salt Pond Mountain, Giles County; (2) Rocky Knob Mountain, Floyd County; and, (3) Shenandoah Valley, Rockingham County, at 945 m, 945 m, and 426 m elevation, respectively. Oxidants were monitored with Mast Meters (Model 724-2) from April 1975 to March 1976 at Site I, from May 1975 to March 1976 at Site II, and from May 1975 to October 1975 at Site III. Increases in oxidants were associated with winds from the north and northeast and stationary high pressure systems. Decreases in oxidants were associated with the passage of cold fronts from the northwest, warm fronts from the south, and winds from the west, southwest, south, and southeast. The National Ambient Air Quality Standard for photochemical oxidants of 8 pphm/1 hour/year was equaled or exceeded for 104, 78, and 39 hours at Sites I, II, and III, respectively. The highest mean hourly oxidant concentrations were monitored on July 3, 1975, the result of an air mass originating from the northeast urban areas. |
