Lenticular copper, lead, cadmium and calcium levels were measured using atomic absorption spectrophotometry in 9 normal and 37 cataractous human lenses. The nuclear parts of the lenses were used for the study in both groups. The lenticular deposition of these four elements in cataract was statistically significant. In the cataractous group, males had higher levels of cadmium compared to females. No lead was detected in normal lenses. The calcium content was significantly higher in cortical cataract whereas the other elements were not correlated with the types of cataract.

“…Also R. M. Al-Ashban et al [6] and other earlier studies [7], [8] illustrate the reduction of hemoglobin and the increase of lead level in blood for individuals using kohl compared with those who do not use kohl. Another study [9] indicates the high level of lead in cataract lenses in comparison with clear lenses. R. M. Al-Ashban et al [6] provide information showing that Kohl mentioned previously in the Arabic and Islamic history is quite different from the currently circulated kohl in Arabic markets by providing considerable evidence to support the suggestion that earlier types of kohl mainly contained antimony sulphide.…”

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.

Nickel, Chromium, Manganese, Iron and Aluminum Levels in Human Cataractous and Normal Lenses

Atomic absorption spectrophotometry was used to detect lenticular nickel, chromium, manganese, iron and aluminum levels in 37 senile cataractous and 9 normal human lenses. The nuclear parts of the lenses were used for the study in both groups. It was found that the concentrations of nickel and iron were significantly higher, and those of chromium, manganese and aluminum were significantly lower in human cataractous lenses than those in normal human lenses. None of the elements showed a significant difference according to sex in both groups. As remarkable differences in chromium, manganese, iron, aluminum and nickel levels exist in cataractous lenses, all the five elements may play some roles in cataractogenesis.
