| Abstract | ||
| In this research, five samples of dust deposited are collected from indoor and outdoor the two hospitals which is Baiji and Salah Al-din general hospital in date 25\7\2022 for two days. This research aims to study the concentrations of the heavy metals in the two hospitals by evaluating the pollution index. X-ray fluorescence (XRF) analysis was carried out using the PEDXRF device. The results showed the concentrations of twenty heavy elements, which have varying effects on human health. A number of pollution indices are used to assess the contamination status in the hospital, namely the Pollution factor (CF), which showed that the heavy elements (Se, Sb, Te, Hg, Cd, Bi, U, Ni, Mo and As) fall into the category of very high pollution in the two hospitals, its value are varying from one location to another. The results of the Nemerow pollution index (PIn) revealed that the sample sites had a highly polluted soil due to the very high concentration Tellurium (Te), which included in the Nemerow equation calculation. The Geo-Accumulation factor (Igeo) gave that the five sample sites had a very high level of pollution in both hospitals. The reason for the increase in the concentration of these indices is due to an increase in the concentration of some heavy metals. | ||
