Ash-forming elements in four Scandinavian wood species. Part 1: Summer harvest

“…Ash forming metals can be found in all biomass, although there is a variation of metal content depending on the biomass, where it is from (available minerals in the soil) or time of harvest [12][13][14]. There is also a large variation in the distribution of ash-forming http://dx.doi.org/10.1016/j.fuel.2015.02.062 0016-2361/Ó 2015 Elsevier Ltd. All rights reserved.…”

“…Ash derived from branch and root wood is richer in many elements than stemwood, while that derived from bark and foliage has concentrations between five and 10 times greater than from stemwood (Werkelin et al 2005). Bark thus produces more ash than stemwood (Pitman 2006).…”

Persian ironwood (Parrotia persica) is native species from Iran and covers 10,54% of the commercial volume. Its wood structure and its chemical composition are affected by growth conditions. The aim of the study was to assess the variation of mineral content (Ni, Fe, Cu, Zn, Pb, Cd), wood density and chemical properties (cellulose, lignin, ash and extractive) of ironwood in relation to altitude above sea level (100, 500 and 700 meter) and pith distance within stem (near to pith and bark and middle point). In addition was investigate the relationship between mineral content with oven-dried density and chemical properties. Results showed that Cd, Cu, Fe, Ni and Zn content (except Pb concentration) increased by increasing of altitude and decreased along radial position within stem from the pith to the bark. Lignin, ash and extractive content increased by increasing altitudes from 100 to 700 meter while cellulose decreased. Radial position had not significant impact on the chemical properties. There are significant relationships between mineral content-chemical properties and between mineral content-wood density (except Cu -density). Forward stepwise regression showed that ash and lignin content had important role on the variation of all of mineral content except on Cd.
