Prosector
Generally, the risks to prosectors are low. Cadavers used for teaching purposes are embalmed before they are encountered by a prosector and students. Embalming fluid usually contains formaldehyde, phenol, Dettol, and glycerine which disinfect and kill pathogens within the cadaver. With exposure to embalming fluid, tissues and bodily fluids, such as blood, become fixed. Prosectors and students working with embalmed cadavers must always wear protective gloves, however this is more for protection against the harsh chemicals used in embalming such as formaldehyde and dettol which can cause moderate to severe skin irritation.
Rosalia Lombardo
That same year, Capuchin catacombs curator Dario Piombino-Mascali discovered a handwritten manuscript written by Salafia, wherein he lists the ingredients used to mummify Rosalia. The embalming formula is described as "one part glycerin, one part formalin saturated with both zinc sulfate and chloride, and one part of an alcohol solution saturated with salicylic acid", and was entered into the body through a single-point injection, most likely into the femoral artery via a gravity injector. Rossella Lorenzi of Discovery News reported that the formalin was used to kill bacteria, the glycerin used to prevent desiccation, and the salicylic acid used to eliminate any fungi within the flesh, with the purpose of the zinc salts being petrifaction.
