“…More important, in an environmental context, is not whether or not an element can be measured in the emissions, but whether or not its effects can be observed in the local environment. , Connor, Anderson, Keith, and Boerngen (1976), and Gough and Erdman (1976) found exponentially decreasing concentrations of a variety of elements in lichen, grass, or sagebrush going away from two western powerplants, including nine which must be regarded as possible stack emittents. These are copper, fluorine, lead, nickel, selenium, strontium, sulfur, vanadium, and zinc.…”

TopographyThe central Utah area is a part of the Colorado Plateaus physiographic province. It is characterized by high plateaus bounded by steep cliffs cut by deep canyons, by precipitous rock ridges, by rock pinnacles and monuments, and by isolated mountain peaks. These are described briefly below.At the north edge of the area is the Roan (or Tavaputs) Plateau, which is divided into east and west parts by the canyon of the south-flowing Green River (called Desolation Canyon to the north and Gray Canyon to the south).The plateau is bounded on the south by the precipitous Book Cliffs.Elevations on the plateau reach nearly 3,140 m above sea level west of the Green River and 2,900 m east of the river. The plateau is dissected by deep canyons that contain streams tributary to the Green River or that flow generally southward across the Book Cliffs.At the west edge of the area is the Wasatch Plateau, which is bounded on the east by high cliffs similar to the Book Cliffs. Elevations on the higher drainage divides of the Wasatch Plateau range between about 2,900 m and 3,445 m above sea level.At the southern end of the area are the north-northwest-trending Henry Mountains, which are characterized by high domal peaks several miles apart separated by broad dissected saddle areas. Mount Ellen, the northernmost and highest peak, is 3,540 m above sea level. In the central part of the area is the north-northeast-trending San Rafael Swell, an uplifted area about 40 km wide and 113 km long marked by bare rock ridges, pinnacles, and narrow

“…The plume deposition model assumes that beyond the distance of maximum deposition, trace element concentrations in soils should decrease with increasing distance from the power plant if the power plant is a significant source of that element. An area of low deposition near the power plant is expected as a result of pollutant release from elevated stacks [16,[30][31][32]. findings of project MOHAVE caused closure of the MPP in December 2005 [33].…”

Desert varnish is a thin manganese-iron rich dark coating that forms on rocks most often in arid climates. This coating may be up to a few hundred microns in thickness and is thought to grow by approximately one micron per thousand years. Recent research has shown that many elements are incorporated into this coating, and, in spite of its slow growth, it may serve as a passive environmental monitor for recent and historical air pollution. To test this hypothesis, small pieces of varnished rock were probed directly by laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS). Results were obtained for 11 elements (13 The LA-ICPMS data indicate that many of the elements commonly found in fly ash from coal-fired power plants (e.g., Cr, Co, Ni, Cu, Zn, Cd, Sn, Sb, Tl and Pb) were highly enriched in the rock coatings in relation to the upper continental crust (UCC). For one of the power plants, where tracer plume studies had been carried out, the highest concentrations in the rock varnish coincide with the peak tracer concentration locations. Thus, these elements in rock varnish hold promise for identifying those geographical regions impacted by nearby power plants. Overall, the results indicate that rock varnish can be used as a passive environmental monitor of relatively recent events, and that the trace element fingerprints held in rock varnish may also hold much potential in forensic air pollution studies.
