Spatial and temporal distribution of ambient nitric acid and ammonia in the Athabasca Oil Sands Region, Alberta
Monthly average ambient concentrations of gaseous nitric acid (HNO3) and ammonia (NH3) were monitored at the Athabasca Oils Sands Region (AOSR), Alberta, Canada, between May 2005 and September 2008.Expand

Distribution of ozone and other air pollutants in forests of the Carpathian Mountains in central Europe.
Ozone (O3) concentrations were monitored during the 1997-1999 growing seasons in 32 forest sites of the Carpathian Mountains. At all sites (elevation between 450 and 1320 m) concentrations of O3,Expand

Ozone distribution and phytotoxic potential in mixed conifer forests of the San Bernardino Mountains, southern California.
In the San Bernardino Mountains of southern California, ozone (O(3)) concentrations have been elevated since the 1950s with peaks reaching 600 ppb and summer seasonal averages >100 ppb in the 1970s.Expand

Air pollution, precipitation chemistry and forest health in the Retezat Mountains, Southern Carpathians, Romania.
In the Retezat Mountains concentrations of O3, NO2 and SO2 in summer season 2000-2002 were low and below toxicity levels for forest trees. While NH3 concentrations were low in 2000, the 2001 and 2002Expand

Air Pollution Distribution Patterns in the San Bernardino Mountains of Southern California: a 40-Year Perspective
Since the mid-1950s, native pines in the San Bernardino Mountains (SBM) in southern California have shown symptoms of decline. Initial studies in 1963 showed that ozone (O3) generated in the upwindExpand
