The aim of the present study was to determine the most significant heavy metal concentration in hen eggs, in particular to compare the heavy metal concentration in eggs originating from industrial poultry farms versus free-range hens. The sampling process was carried out between October and December 2018, in the Republic of Kosovo. In total, 22 random egg samples were collected, with 54.5% and 45.5% of samples coming from poultry farms and free-range hens, respectively. The measurements of the heavy metals were taken by inductively coupled plasma mass spectrometry (ICP-MS), using a wide range of elements, and only the most important elements were reported, such as Cr, Mn, Fe, Ni, Cu, Zn, As, Cd, Hg, and Pb within the range of 0.48–8.45, 38.77–289, 4286.59–15383.74, 0.45–144.74, 61.68–550.59, 1078.04–11378.56, 0.29–35.42, 0.27–6.54, and 0.04–1.41 μg kg−1, respectively. This study revealed that the heavy metals in eggs from free-range hens are richer in essential elements such as Mn, Fe, and Zn, while poultry farm eggs contain a higher contribution of Cr, Cd, As, and Pb. However, the daily intake of heavy metals from egg consumption was lower than the WHO-FAO advised provisional daily intake. Therefore, egg consumption does not exceed the safety levels of toxic metals and does not pose any risk to human health.

According to ALARA principle for radiation protection, dentists must expose patients to lowest possible radiation with sufficient quality of imaging. Radiation exposure arising from dental radiology is considered low; a child may undergo repeated dental radiological procedures throughout childhood and adolescence. [...]the risks associated with cumulative doses should be taken into consideration (1).The thyroid gland is more susceptible to radiation exposure during dental radiographic exams given its anatomic position, particularly to children (2, 3). According to new Basic Safety Standard for procedures using medical radiological equipmentmust put in placespecific diagnostic reference levels (DRLs) also DRLs are recommended by the International Commission of Radiological Protection (ICRP) (5). CONCLUSION From results, we conclude that the mean of DAP (mGy cm2) for single intraoral examination is 26.8, 29.6 and 39.7 for incisor, premolar and molar, respectively. [...]the mean of DAP (mGy cm2) value for panoramic dental radiology is 62.7, 74.1 and 90.3 for child, adult and large adult, respectively. 3rd quartile are calculated Recommended DRLs value, for intraoral radiography programs: incisor, premolar and molar are: 28.5, 36.5 and 50.3 mGy cm2, respectively.
