Eggs from hens raised on rural or domestic farms are a good indicator of environmental contamination, as the hens are in close contact with the ground and the air and can therefore accumulate heavy metals and other toxic contaminants from the environment as well as from the diet. In this paper, we report the results of the determination of 19 trace elements (As, Be, Cd, Co, Cr, Cu, Hg, Mo, Mn, Ni, Pb, Sb, Se, Sn, Sr, Tl, U, V, Zn) in 39 hen egg samples collected from domestic poultry farms in the territory dubbed the "Land of fires" in the Campania region (Italy). This area is characterized by environmental problems caused by the illegal dumping of industrial or domestic waste in fields or by roadsides. In some cases, these wastes have been burned, thereby spreading persistent contaminants into the atmosphere. The content of trace elements in whole egg samples was determined by mass spectrometer after a microwave-assisted digestion procedure. Because European legislation does not indicate maximum values of these elements in this foodstuff, the results were compared with the content of trace elements reported in literature for eggs, in particular home-produced eggs, in various countries. In some cases (Cd, Cu, Ni, Mn), the content determined in this study was in line with those reported elsewhere, in other cases (Pb, Cr), lower values were found.
来自农村或家庭农场饲养母鸡所产的鸡蛋是环境污染的良好指示物，因为母鸡与地面和空气密切接触，因此能够从环境以及饮食中积累重金属和其他有毒污染物。在本文中，我们报告了对从意大利坎帕尼亚地区被称为“火之地”的家禽养殖场采集的39个鸡蛋样本中19种微量元素（砷、铍、镉、钴、铬、铜、汞、钼、锰、镍、铅、锑、硒、锡、锶、铊、铀、钒、锌）的测定结果。该地区存在一些环境问题，原因是工业或生活垃圾非法倾倒在田地或路边。在某些情况下，这些废物被焚烧，从而将持久性污染物扩散到大气中。全蛋样本中的微量元素含量通过微波辅助消解程序后用质谱仪测定。由于欧洲立法未指明这些元素在该食品中的最大值，因此将结果与文献中报道的各国鸡蛋（特别是自产鸡蛋）中的微量元素含量进行了比较。在某些情况下（镉、铜、镍、锰），本研究测定的含量与其他地方报道的一致，在其他情况下（铅、铬），则发现含量较低。
