found in all plant species. The uptake level of air-borne strontium by plants depends
on physico-chemical form of Sr, the type of deposition (wet or dry), the time between
fallout and first rain and the weather illumination (Burger and Lichtscheidl 2019).
After incorporated by plants, it enters the food chain and causes threat to human
health and the environment. Stable strontium can be released into the atmosphere
from natural activities and then redeposited on the earth by dry fall or wet deposition.
The emissions from burning of coal and oil may increase the strontium level in the
air.
Sr showed a moderate to small variation (CV % = 26% or close to the low variation range of 25%). The spatial distribution pattern of Sr looks likely homogenous
over the country with a narrow range of variation (from 6.0 to 39.3 mg kg
−1 ) and
a small value of skeweness and kurtosis (0.57 and 0.51 respectively). The spatial
analysis of Ba (linear model) (Fig. 3.12) indicates a very slight decline from the
south to the north direction of the country (Sr = 23.31 − 0.0817 × n, n represents
the number of sampling site). Higher Ba concentration was found in St. 24 (Elbasan
area) by indicating the anthropogenic pollution from iron metallurgy. The next high
Sr contents were found in the coastal area (St. 2, 5 and 6) that is probably derived
from the sea spry emission in the area.
Sr showed strong and significant correlations (r > 0.6, p < 0.01) with typical crustal
elements such as Li, Ba, and V, and moderate and significant correlations (r = 0.4 −
0.6, p < 0.01) with V, Zr, Hf, Sc, La, Ce, Yb, Th, U, Fe, Ta, W, and Cs by probably
indicating its lithogenic origin from wind blowing soil dust particles.
