Thus, at a relative pressure, P/Po, of 0.0936 the adsorption space Wv was 0.467 cm'Vg, and at a P/Po of 0.3448, Wv was 0.478 cm:Vg.Values for the kinetic adsorption capacity We were calculated for the various vapors by using Equation 7, inserting into

The Nature and Distribution of Metals in Soils of the Sydney Estuary Catchment, Australia

“…Australia (Gulson et al 1981;Tiller et al 1987), Canada (Franzin et al 1979), Europe (Alcamo et al 1992), China ) and the Middle East (Erel et al 1997). An investigation of topsoil metals in a subcatchment of Sydney estuary (Homebush Bay) indicated 48%, 44% and 76% of surface Cu, Pb and Zn, respectively were attributable to atmospheric deposition (Hodge 2002).…”

Lead contamination in smelting and mining environments and variations in chemical forms and bioavailability

“…Zoltai (1988) found above-background concentrations of Pb, Zn, Cu and As in peat up to 100 km from the Flin Flon base metal smelter in Canada. According to Franzin et al (1979), the smelter was a significant source of these metals, and possibly airborne sulfate over a 250,000 km 2 area. Dumontet et al (1990) found elevated concentrations of Pb, Zn, Cd, Cu and Ni in peat 42 km away from a smelter in Noranda, Quebec.…”

Multi-trophic level response to extreme metal contamination from gold mining in a subarctic lake

“…Large quantities of arsenic (among other metal(loid)s) were released as emissions and tailings from smelting and refining in Flin Flon, Manitoba [11,12] and Sudbury, Ontario [13]. In Canada, historic gold mining represents one of the major sources of arsenic contamination to the environment because many recoverable gold deposits are found in arsenic bearing sulfide deposits [9].…”
