The sustenance of humans and livestock depends on the protection of the soil. Consequently, the pollution of the soil with potentially toxic elements (PTEs) is of great concern to humanity. The objective of this study is to investigate the source apportionment, concentration levels and spatial distribution of PTEs in selected soils in Frýdek-Místek District of the Czech Republic. The total number of soil samples was 70 (topsoil 49 and 21 subsoils) and was analysed using a portable XRF machine. Contamination factor and the pollution index load were used for the assessment and interpreting the pollution and distribution of PTEs in the soils. The inverse distance weighting was used for the spatial evaluation of the PTEs. The results of the analysis showed that the area is composed of low-to-high pollution site. PTEs displayed spatial variation patterns. The average PTE concentration decreases in this Fe > Ti > Ba > Zr > Rb > Sr > Cr > Y>Cu > Ni > Th order for the topsoil and also decreases in this Fe > Ti > Zr > Ba > Rb > Sr > Cr > Y > Cu > Ni > and Th order for the subsoil. These PTEs Cr, Ni, Cu, Rb, Y, Zr, Ba, Th, and Fe were far above the baseline European average value and the World average value level, respectively. The source apportionment showed the dominance of Cr, Ni, Rb, Ti, Th, Zr, Cu, Fe in the topsoil, while the subsoil was dominated by all the PTEs (factor 1 to 6) except Ba. The study concludes that indiscriminate human activities have an enormous effect on soil pollution.
人类和牲畜的生存依赖于土壤的保护。因此，土壤中潜在有毒元素（PTEs）的污染对人类来说是一个巨大的关注点。本研究的目的是调查捷克共和国弗里德克-米斯泰克地区选定土壤中 PTEs 的来源分配、浓度水平和空间分布。土壤样本总数为 70 个（表土 49 个，底土 21 个），并使用便携式 XRF 仪器进行分析。污染因子和污染指数负荷用于评估和解释土壤中 PTEs 的污染和分布。使用反向距离加权法进行 PTEs 的空间评估。分析结果表明，该地区由低到高污染的地点组成。PTEs 显示出空间变化模式。表土中 PTE 平均浓度呈下降趋势，按 Fe>Ti>Ba>Zr>Rb> Sr>Cr>Y>Cu>Ni>Th 顺序排列，底土中 PTE 平均浓度也呈下降趋势，按 Fe>Ti>Zr>Ba>Rb> Sr>Cr>Y>Cu>Ni>Th 顺序排列。这些 PTEs Cr、Ni、Cu、Rb、Y、Zr、Ba、Th 和 Fe 分别远高于欧洲基准平均水平和世界平均水平。来源分配表明，Cr、Ni、Rb、Ti、Th、Zr、Cu、Fe 在表土中占主导地位，而底土中除 Ba 外，所有 PTEs（因子 1 至 6）都占主导地位。研究结论认为，人类的无差别活动对土壤污染有巨大影响。
