- Abstract
In this study, selected heavy metals, present in park soil samples from different areas in Amman-Jordan, were evaluated. Soil samples were collected from 30 different parks in 3 different areas during the summer season. The physiochemical properties that play a main role in metal mobility were determined, such as pH that showed neutral to alkaline values. The moisture content revealed low value due to the high evaporation level during sample collections, and finally, the organic matter content was full in high contents. Park soils' metal contents were extracted and then examined by flame atomic absorption spectroscopy. The data were exposed to principle component analysis and hierarchical cluster analysis to reveal the variations of park metal levels as a result of geographical park areas, to show the metals that were responsible for clustering parks, and finally, to facilitate the future metal's location prediction and parks clustering of unknown soil samples based on their metal contents. The results showed that thirty parks of different soil samples were grouped into two clusters. Among the parks, two areas of high traffic jams and construction processes were clustered together due to the distinct content of Pb, Cu, and Ni where the third area shows distinct content of Zn that was responsible for clustering parks of this area alone. Classification of park soils according to the similarities of their chemical contents based on Flame Atomic Absorption Spectrometry outcomes will help define the sources of the studied heavy metals and provide clear information about the common health symptoms / issues caused by exposure to these heavy metals in the areas that have been clustered in one group.
