Evaluation of the noncarcinogenic health risks of copper in Wasit Governorate dust

An investigation was conducted in Wasit Governorate, where 32 indoor air samples were collected from popular locations and tested for the concentration of the metal copper (Cu). The samples were taken from air conditioning systems and then diluted with distilled water before being analyzed using Atomic Absorption Spectroscopy. The results indicated that the concentration of Cu exceeded the permissible limits set by international standards. The minimum, maximum, and average concentrations of Cu in the samples were found to be 1.446E-06, 9.236E-04, and 2.8E-05, respectively. Furthermore, a detailed assessment of carcinogenic and non-carcinogenic toxic risks revealed significant findings that warrant serious attention.
