Mercury is a naturally occurring heavy metal and a well-recognized environmental toxin. When absorbed into the bloodstream at elevated levels, mercury is also extremely harmful to people, causing a range of problems including cognitive impairments, skin rashes, and kidney problems [1].
In this illustration, it’s possible to see in red blood cells the effects of mercury chloride, a toxic chemical compound now sometimes used as a laboratory reagent. Normally, healthy red blood cells have a distinct, doughnut-like shape that helps them squeeze through the tiniest of blood vessels. But these cells are terribly disfigured, with unusual spiky projections, after 24 hours of exposure to low levels of a mercury chloride in solution.
