“…According to Dobbs and Grant (Dobbs and Grant, 1978) there is no problem for As volatization at 60 • C. They also state that 13-27, 22-44, and 70-77% of arsenic is volatilized at temperatures of 400, 800, and 1000 • C , respectively. The temperature for Sb volatization process is between 550 and 600 • C according to W.C. Butterman and J.F.…”

Intense mining activities in Minas Gerais State - Brazil brings out tons of waste to the environment. Considerable concentrations of toxic elements penetrate the soil, ground waters and rivers. This endangers the environment quality not only in the surrounding areas but also in ichthyofauna and in more distant areas of cattle raising and agricultural activities. After seasonal floods, veterinary clinic studies have shown that most animals raised in this region are affected by symptomatologic nervous diseases, still not clearly diagnosed, which suggests intoxication. These pathologies are mostly noted after floods. Instrumental Neutron Activation Analysis was applied to determine Al, As, Au, Ba, Br, Ca, Cl, Co, Cr, Cs, Cu, Fe, Hg, K, La, Mg, Mn, Na, Nd, Rb, Sb, Sc, Sm, Th and Zn in environmental samples. The obtained results show that the water and sediment contaminated with heavy metals and toxic elements from the Das Velhas River upstream basin, the mining region, carry contamination to the ichthyofauna and farming region within a distance of approximately 400 km.

“…However, combustion and landfill of CCA-treated wood wastes suggested may result in the release of environmental pollutants. For example, some studies result that the combustion of CCA-treated wood wastes causes the release of arsenic into the atmosphere [1][2][3]. On the other hand, when the wood is landfilled, determining if the toxic metals have diffused from the waste wood into the soil and groundwater is difficult.…”

“…However, energy recovery is difficult to perform in the case of CCA-treated wood waste due to the toxic materials that are released during combustion. Dobbs and Grant [3] report that 59% of arsenic is volatilized at a temperature of 1000 • C, and McMahon et al [17] state that 13-27%, 22-44%, and 70-77% of arsenic is volatilized at temperatures of 400, 800, and 1000 • C, respectively. Hirata et al [11] also report similar tendencies in the volatilization of arsenic during combustion.…”
