Study of Heavy Elements and Radioactivity Concentrations in Some Eye Cosmetics Commonly Used in Arabic Regions

Abstract

Abstract-Thirteen samples of eye cosmetics including five samples of artificial eye cosmetics and eight samples of traditional eyeliner (kohl) were collected from various Arabic markets, and analyzed using inductively coupled plasma-optical emission spectrometer (ICP-OES) to assess concentrations of the most toxic elements (arsenic (As), cadmium (Cd), mercury (Hg) and lead (Pb)), and high purity germanium detector (HPGe) to determine radioactivity concentrations of the natural radionuclides 238 U, 235 U, 226 Ra, 232 Th and 40 K. The average concentrations of the elements As, Cd, Hg and Pb are a bit high in some samples in a way that they might cause some harm to human health, while the average values of the activity concentrations for 238 U, 235 U, 226 Ra, 232 Th and 40 K are not that high. Annual absorbed amounts of heavy elements from daily applied kohl were calculated based on roughly assumption that about 50 % of the applied kohl is absorbed into the body. An appropriate simulation has been done for the eye using the MCNP code to estimate the dose rate of the lens of the eye as a result of using contaminated kohl.

Alpha Emitters Radioactivity Concentrations in Some Cosmetics Used in Iraq Using Lr-115 Detector

“…Comparing with the other available Fundamental and applied physics measurements its very low than the results of 7.9-37.6 Bq/Kg estimated in reference [25]. In the kohl sample, the radium concentration is 0.105 Bq/Kg which is lower than 0.866 Bq/Kg the results of reference [26]. The obtained results of cosmetics samples showed that, the samples have different concentrations for radon or radium from one type of cosmetic to another, due to its producing composition materials which need to another investigation tools not available here, to know the materials that increase the radiation concentration.…”

Chemical and Physical Investigations of Arabian Eye Kohl Brands as Cosmetic in Libya

“…A research carried on a different samples of eye kohl collected from state of Libya, Egypt and Kingdom of Saudi Arabia (KSA) and the results indicate that kohl samples are contaminated with a significant concentrations of semi and heavy metals such as As, Cd, Hg, and Pb [24]. In United Arab Emirates (UAE), a survey of minerals was carried out for 53 kohl samples.…”
