Presence of heavy metal compounds, such as mercury, chromium, and lead, were detected in cultured mammalian cells, LLC-MK2, by means of energy disperse type electron microscope. Introduction of these heavy metal compounds at high concentrations from 1 to 10 mM in the culture medium, resulted in the morphological change of cultured cells after 2 days of incubation at 37℃. The change was accompanied by the appearance of intracytoplasmic electron-dense granules from which significant levels of metal-specific signals were recorded. On the other hand, no significant metal-specific signals were recorded in the specimens when the cells were maintained for 2 days under media containing less than 0.1 mM of these metal compounds. The results indicated the capacity and limitation of the equippment to detect the accumulation of the heavy metals in medical or biological specimens.
