It is well known and proven that heavy metal contamination of the soils can severely affect the health of the people living in the contaminated areas given the ease with which trace elements can enter the human body. In addition-to agricultural crop depreciation as well as soil erosion, soil pollution can negatively affect the natural function of ecosystems. While certain heavy metals in high doses can be harmful to the body, others such as cadmium, mercury, lead, chromium, silver and arsenic in minimal amounts have delusional effects on the body, causing acute and chronic intoxication. Our research is focused on the identification of heavy metals from the soil (O, Al, Ca, Cu, Fe, K, Mg, Na, P, Pb, Si, Ti, Zn) in 3 areas in Transylvania where factories were in operation, using 4 methods: UV–VIS spectrometry, AAS, SEM-EDAX and X-ray diffractions. High levels of very toxic trace elements such as lead, aluminum, cadmium were found near the studied areas, especially using SEM-EDAX and AAS methods. Knowledge on the soil concentration of TEs, the time exposure and the side effects can lead us to predict the health status of the exposed population. In our study, by determinating the concentration of TEs we set out to formulate a prediction on the health status of the exposed population using literature data.

众所周知，土壤中的重金属污染会严重影响生活在污染地区的人们的健康，因为微量元素很容易进入人体。除了农作物贬值和土壤侵蚀外，土壤污染还会对生态系统的自然功能产生负面影响。虽然某些高剂量的重金属可能对身体有害，但其他如镉、汞、铅、铬、银和砷等微量元素对身体有妄想作用，导致急性和慢性中毒。我们的研究重点是在工厂运营的特兰西瓦尼亚 3 个地区从土壤中鉴定重金属（O、Al、Ca、Cu、Fe、K、Mg、Na、P、Pb、Si、Ti、Zn） ，使用 4 种方法：UV-VIS 光谱法、AAS、SEM-EDAX 和 X 射线衍射。在研究区域附近发现了高水平的剧毒微量元素，如铅、铝​​、镉，特别是使用 SEM-EDAX 和 AAS 方法。关于 TEs 的土壤浓度、暴露时间和副作用的知识可以引导我们预测暴露人群的健康状况。在我们的研究中，通过确定 TE 的浓度，我们着手使用文献数据制定对暴露人群健康状况的预测。
