soil dust in the atmosphere. Hg is a global pollutant and its origin in the moss is
mostly derived from long-range transport local factors and transboundary pollution.
The local anomalies distributed geographically indicate a substantial Hg contribution
from the local sources.
3.4 Spatial Distribution of Crustal Elements
3.4.1 Aluminium, Al
Al is a typical crustal element that is probably supplied to the moss in the form of
windblown soil dust fine particles. Aluminnium shows a moderate variation (CV %
= 52%) and its spatial distribution (Fig. 3.4) looks likely uniforms over the country.
It is supported by the similar values of mean concentrations among three different
transects (1679, 1687 and 1690 mg kg
−1 respectively), as well as by strong and
significant correlations between Al (r > 0.7, p < 0.01) and typical crustal elements
(Li, Fe, Hf, Ta, W, Sc, Ce, Cs, Ba, Na, Ni and Co) that are soil dust derived elements.
The spatial analysis of Al (linear model) (Fig. 3.4) indicates a stable distribution of
Al from the south to the north direction of the country (Al = 1767 − 4.67 × n, n
represents the number of sampling site) .
The highest Al concentrations were found in the areas of Fe mines (St. 38 and
41) by indicating the anthropogenic pollution from mining activity and the local
geogenic factors. The next high Al content was found in St. 24 (Elbasan region)
that is derived from anthropogenic emission from steel and iron metallurgy plant of
Elbasan.
