Potentially toxic elements (PTE) are considered to be dangerous threats, both for human health and the environment. Here, contamination level, sources, ecological risks posed by PTE were investigated in 19 topsoils from agricultural lands Bandar Abbas County on southern coast of Iran. The soil fraction <63 μm was used analysis pseudototal contents (arsenic, cadmium, cobalt, chromium, copper, lead, manganese, molybdenum, nickel, vanadium, zinc). results analyzed using principal component (PCA) Pearson’s correlations, different pollution indices [enrichment factor (EF), (Cf), modified degree (mCd), potential risk index (PERI). showed that levels studied soils low moderate, while average PERI values indicate range high area. Correlations PCA analyses suggest have three possible origins: geogenic (chromium, zinc), anthropogenic (cadmium, phosphorus lead) atmospheric (arsenic) sources. These findings helpful long-term assessment County.
