Spatial Analysis Plot for Sb
Linear Trend Model
Sb = 0.118 + 0.00014×n
Fig. 4.7 Spatial analysis plot of Sb
steel metallurgy (St. 24). The same as Zn, high Sb content (0.452 mg kg
−1 ) was
found in moss samples collected at Kruja region (St. 27) that is probably linked with
a strong anthropogenic effect of kiln operations that were using waste materials such
as tires wear, unselected urban wastes, woods etc., as burning materials during the
CaO production. The next high Sb contents were found in mosses of St. 4, 13, 14,
22, 25 and 41 that are probably derived by marine environment, geogenic factors,
mining activity, former non ferrous metal smelting industry, and the wind blowing
mineral fine particles from the mineral waste deposits.
Sb showed moderate and significant correlations (r = 0.4 − 0.6, p < 0.01) (see
the Appendix, Tables A1 and A2) with Cu, Co, Cr, Ti, Ta, W, Sc, most of the light
lanthanides, Th and U that are typical elements of coal burning by indicating strong
effect of long-range transport of the pollutants throughout the country.
4.8 Molibdenum, Mo and Selenium, Se
Mo and Se are naturally occurring in the environment. Se is an essential metalloid
that has beneficial effects to human health and plants. Mo and Se show similar
geochemical behaviours and are often appear as associated elements of the metal
sulfides (Cu, Ag and sulfide minerals) that are also present in the North and the
North-East part of Albania particularly as Cu sulfides (Lazo et al. 2007). Mo can
also be found in Cu, U and Zn ore deposits, usually as metal-molybdates. The main
anthropogenic sources of Mo and Se are mining, agriculture, soils with high content
of Mo and Se, coal and petroleum burning, and forest fires.
