Abstract

In this study, the concentrations of heavy and toxic metals in the most widely used face powder in the local market in the city of Tiji (Libya) were estimated. Four powder samples were collected, prepared, and analyzed using X-ray fluorescence (XRF) to detect several heavy elements such as copper, nickel, lead, chromium, arsenic, iron, magnesium, mercury, zinc, tin, cadmium, and others. The results of this study showed that some
heavy elements were within the permissible limits, while others were higher than previous studies and exceeded the permissible level set by the World Health Organization, which is a cause for concern due to the serious health problems it may cause.
