| Zusammenfassung |
| This study extends the application of the portable X-ray fluorescence
(PXRF) spectrometry to the examination of elements in semi-arid urban landscapes
of the Southern High Plains (SHP) of the United States, focusing on
golf courses. The complex environmental challenges of this region and the
unique management practices at golf course facilities could lead to
differences in concentration and in the chemistry of elements between managed
(irrigated) and non-managed (non-irrigated) portions of these facilities.
Soil samples were collected at depths of 0–10, 10–20, and 20–30 cm
from managed and non-managed areas of seven different facilities in the city
of Lubbock, Texas, and analyzed for a suite of soil properties. Total
elemental quantification was conducted using a PXRF spectrometer. Findings mostly indicated
no significant differences in the concentration of examined elements between the
managed and non-managed areas of the facilities. However, strong positive
relationships (R = 0.82−0.91, p < 0.001) were observed among elements (e.g.,
Fe on the one hand and Cr, Mn, Ni, and As on the other; Cu and Zn; As and Cr) and between these
elements and soil constituents or properties such as clay, calcium
carbonate, organic matter, and pH. The strengths of these relationships were
mostly higher in the non-managed areas, suggesting a possible alteration in
the chemistry of these elements by anthropogenic influences in the managed
areas. Principal component and correlation analyses within
the managed areas suggested that As, Cr, Fe, Mn, and Ni could be of
lithogenic origin, while Cu, Pb, and Zn could have anthropogenic
influences. Only one possible, likely lithogenic, source of the elements was
identified within the non-managed areas. As evidenced by the study, the PXRF
spectrometer can be a valuable tool for elemental quantification and rapid investigation
of elemental interaction and source apportionment in semi-arid climates. |
