“…The release rate of nickel from various boiler types varies substantially. Several studies (Nodelman et al, 2000;Han et al, 2002;Tolvanen, 2004) indicate that about 36%-75% of Ni release into atmosphere for pulverized-coal boilers, while the ratio may reduce to approximately 5%-22% for stokers (Wang et al, 1996;Zhang et al, 2003;Li et al, 2005) and 53%-94% for fluidized-bed furnaces (Klika et al, 2001;Reddy et al, 2005;Bartoňová and Klika, 2009). The detailed release rates of Ni from different combustion boilers are compiled and listed in Table 2.…”

“…ESPs can achieve a Ni removal efficiency of 79%-100%, while the Ni removal efficiency of fabric filters (FFs) range from 82% to 100% (Helble, 2000;Nodelman et al, 2000;Klika et al, 2001;Tolvanen, 2004;Ito et al, 2006;Meij and Te Winkel, 2007;Nyberg et al, 2009). Cyclones show relatively low Ni removal efficiency with about 40% (Gogebakan and Sel Uk, 2009).…”

“…The MPP was shut down in December of 2005, in part because plumetracer studies implicated it as an important source of haze in the GCNP [14]. Thus, seasonal plumes for the MPP have been mapped, and, since fly-ash is a possible source of heavy metals, samples of desert varnish were collected at locations in the MPP plumes [16,17].…”

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.
